Issue number 457 of the CIES Football Observatory Weekly Post ranks almost 800 clubs from 48 leagues around the world according to the average age of recruitment of the first team players signed over the last ten transfer windows (July 2019 to date). The lowest value overall was recorded for the Austrians of RB Salzburg (20.93 years), while the highest was measured for the Qatari side Al-Gharafa SC (30.27 years).

Another member of the Red Bull galaxy, RB Bragantino, ranks second (21.72 years). The Basques of Athletic Club (21.90) complete the podium with nevertheless few recruitments, most of their players coming directly from the youth academy. Also in the top ten are Slovenia’s NK Bravo, two Ukrainian clubs (Shakhtar Donetsk and Dynamo Kyiv), two Belgians (Genk and Club Brugge), one Swede (Elfsborg) and one Slovakian (Ružomberok).

The Post also presents the average age of players signed during the penultimate five-year period (July 2014 to June 2019), which makes it possible to measure trends. Among the clubs having the most rejuvenated their recruitment, the top three are Athletic Club (-4.11 years), RB Bragantino (-4.07) and Brighton & Hove (-3.36). At the other end of the scale, the teams that have opted for more experienced signings notably include Fluminense (+2.95 years), Olympique Lyonnais (+2.39) and Inter (+2.32).

The Weekly Post number 456 of the CIES Football Observatory presents the ten players with the highest estimated transfer values across 66 leagues worldwide (the most important outside the big-5). The rankings were drawn up on the basis of a powerful property statistical model*, explaining over 80% of the price differences observed for about 6,200 paying fee transfers that took place over the last decade.

Stepping stone league to the big-5 per excellence, Portugal’s Primeira Liga brings together the three footballers playing outside the world’s top five competitions with the highest estimated transfer values: António Silva (Benfica, €114m), João Neves (Benfica, €95m) and Gonçalo Inácio (Sporting CP, €87m). Real Madrid’s new recruit Endrick (Palmeiras, €80m) tops the list for players active outside Europe, ahead of compatriots Pedro (Flamengo, €42m) and Paulinho (Atlético Mineiro, also €42m).

The following players are the best valued in the other main leagues analysed: Jorrel Hato (€78m) in the Netherlands, Georgiy Sudakov (€52m) in Ukraine, Georginio Rutter (€41m) in the English Championship, Oscar Gloukh (€36m) in Austria, Matthew O’Riley (€31m) in Scotland, Antonio Nusa (€28m) in Belgium, Martin Baturina (€28m) in Croatia, Cristian Medina (€24m) in Argentina, Thiago Almada (€23m) in the MLS and Julián Quiñones (€21m) in Mexico.

The 93rd CIES Football Observatory Monthly Report analyses the high-pressure data produced exclusively by the French company SkillCorner. It notably reveals the link between the frequency with which players are subjected to high intensity pressure from opponents, the position they occupy on the pitch and the style of play of their team.

During the 2023 and 2023/24 seasons, outfield players from teams in the 28 leagues studied experienced an average of 9.2 instances of high-intensity pressure per match. The highest values were measured for dominant teams: Manchester City (15.2 pressures per game), Bayer Leverkusen (13.9) and Columbus Crew (13.5). Manchester City also tops the table for the percentage of ball retention under high pressure (84.2%), followed by Real Madrid (81.2%) and Paris St-Germain (80.8%).

The study also highlights the players who stand out most positively in terms of ball retention under high pressure, based on the residuals of a statistical model that takes into account their position and their team’s style of play. This approach is particularly useful for scouting purposes to target recruits with an unexploited potential.

The 455th CIES Football Observatory Weekly Post ranks teams from 54 leagues around the world according to their shooting efficiency. The latter was measured from the residuals of a statistical model explaining 78% of the differences in goals scored per team (not including penalties) on the basis of three variables produced by Wyscout: the number of expected goals according to the dangerousness of the chances created (also not including penalties), the number of shots on target and in total.

With 0.69 more non-penalty goals than expected per game, Greece’s PAOK FC have the most positive gap in absolute terms, reflecting judicious shooting decisions, as well as particularly effective finishing. Portugal’s Sporting CP (+0.59) and Italy’s AS Roma (+0.52) complete the podium. The Italians outrank Inter and Arsenal in the five major European leagues, followed by Bayern Munich, Bayer Leverkusen and Valencia.

In terms of the most negative gaps, with 0.63 fewer goals than expected per game, Melbourne City top the list, ahead of four particularly inefficient big-5 league teams: OGC Nice (-0.56), Olympique Lyonnais (-0.49), Rayo Vallecano (-0.48) and Montpellier (-0.47). Everton and Köln are the least effective clubs in the other leagues of the European big-5, Go Ahead Eagles in the Dutch Eredivisie, Vizela and Benfica in the Portuguese Primeira Liga, as well as RSC Charleroi in the Belgian Pro League.

The 454th CIES Football Observatory Weekly Post presents the 20 outfield players for six positions playing in 28 leagues around the world whose number of accelerations* per match (SkillCorner data) deviates most positively from the value expected with respect to their position and their team’s style of play (level of possession, pressure and verticality), according to a statistical model explaining more than half of the differences observed between players.

With 1.93 more accelerations per game than expected, Victor Osimhen (Napoli) ranks first among centre forwards. The Nigerian is ahead of Ghanaian Emmanuel Boateng (Rio Ave) and Ivorian Vakoun Bayo (Watford). Among the wingers, the podium is made up of Álvaro García (Rayo Vallecano), Armand Laurienté (Sassuolo) and Felipe Anderson (Lazio). Dutchman Guus Til (PSV Eindhoven) tops the list for attacking midfielders.

As for the other positions, Sessi D’Almeida (Pau) is ahead of Josh Laurent (Stoke City) and 19-year-old Ezechiel Banzuzi (OH Leuven) among central or defensive midfielders; Jeremie Frimpong (Bayer Leverkusen) crushes the competition for wing or full backs with the greatest positive gap overall (x2.1 compared to the expected value) ahead of Marlon Fossey (Standard Liège); Danilo (Juventus), Ruan (Sassuolo) and Davinson (Galatasaray) make up the top three among centre backs.

* Accelerations refer to runs of at least 0.7 seconds at >10.8 km/h/s. Only footballers who played at least 1,000 domestic league minutes in the current or last completed season, of which more than three quarters in the same position, are included in the rankings.

Issue number 453 of the CIES Football Observatory Weekly Post analyses the StatsPerform and Wyscout data on the number of cards, fouls and injury time measured over the last year for 71 leagues around the world. The study shows major differences between leagues in terms of all the indicators taken into account, reflecting different ways of interpreting the game by both players and referees.

In terms of red cards, the values range from 0.61 per match in Bolivia to 0.10 in the Japanese J2. For yellow cards, the extremes were measured in Uruguay (6.07) and, again, in the Japanese J2 (2.73). As for fouls, the maximum was recorded in the Brazilian Serie B (30.3 per match), while the minimum was observed in Norway and the Netherlands (20.0 in both cases). In terms of extra time, the data ranges from almost 14’ in Qatar and Saudi Arabia to 6’ in Finland and Slovakia.

If we relate the number of fouls to yellow cards (second yellow included), the values stretch from about one card every four fouls in Chile to one every eight in Japan. Among the European big-5 leagues, this ratio is much higher in the French Ligue 1 (6.8) than anywhere else (around 5), which may reflect either a lower propensity to hand out cards or a greater tendency on the part of referees to whistle for ‘small’ fouls.

The 92nd CIES Football Observatory Monthly Report analyses from a spatial perspective the origin of the >€75 billion transfer revenues collected by clubs worldwide between 2014 and 2023. Overall, clubs have generated around two-thirds of their transfer incomes from international deals. However, this proportion varies greatly from country to country, with a minimum of 37% for English clubs and a maximum of 73% for French teams among the big-5 league associations.

Teams from only three countries other than England - among the twenty whose clubs generated the most transfer incomes during the last decade - collected less money from foreign teams than from domestic ones: China (22%), Mexico (44%) and Italy (48%). The dependence on foreign transfers is much greater for clubs in associations such as Portugal (91%), the Netherlands (90%), Belgium (87%), Brazil (86%), Argentina (83%) or Turkey (77%).

For many countries, England is the main fund provider for international transfers. Among the nine other associations whose clubs received the most indemnities between 2014 and 2023, this is notably the case for the Netherlands (38% of total transfer revenues were generated from England), France (32%), Germany (31%), Spain (30%), Portugal (30%), Belgium (25%) and Italy (14%). Brazil (Spain) and Argentina (Italy) are the only exceptions.

Number 452 of the CIES Football Observatory Weekly Post presents the 169 clubs in the world whose volume of incoming or outgoing player transactions over the last five seasons exceeded the €100 million threshold, as well as their net spending for the last ten, the last five and the last season. In terms of the volume of money exchanged, Chelsea is clearly in the lead with €2.572 billion, followed by Manchester City (€1.726) and Paris St-Germain (€1.404).

In total, 14 teams from seven countries have ’shuffled’ over a billion euros in five seasons: five from England, two from Spain, two from Germany, two from Italy, one from France, one from Portugal and one from the Netherlands. Twenty-four countries, including five outside Europe, are represented among the 169 teams whose volume of transactions exceeded €100 million, with a maximum of 30 clubs for England.

In terms of balance sheets, the values for the current season range from -€384m for Al-Hilal to +€167m for Southampton. Over the last five seasons, the figures stretch from -€782m for Chelsea to +€354m for Benfica. Finally, over the last decade, the values go from -€1.348bn for Manchester United (with only Chelsea also totalling a >€1bn deficit) to +€732m for Benfica. All the sums presented include any add-ons, regardless of their effective payment.

On this Valentine’s Day, the CIES Football Observatory Weekly Post highlights the footballers from 60 leagues around the world who have been in the first team squad of their current club for the longest uninterrupted period. Russian international goalkeeper Igor Akinfeev is the most loyal player overall: he has been defending the CSKA Moscow goal for 21 years.

In the European big-5 leagues, two Germans top the table: Thomas Müller (Bayern Munich) and Tony Jantschke (Borussia Mönchengladbach). They are currently playing their sixteenth consecutive season with their respective clubs. Three Spaniards complete the podium in the big-5: Athletic Club’s Iker Muniain and Óscar de Marcos, as well as Atlético de Madrid’s Koke Resurrección.

For the other European leagues surveyed, Akinfeev is ahead of compatriot Rizvan Utsiev (Akhmat Grozny), Scotland’s Lewis Stevenson (Hivernian) and Norway’s Steffen Hagen (Odds BK). Outside Europe, Emirati goalkeeper Ali Khaseif (Al-Jazira) tops the list ahead of the Shanghai Port duo Huikang Cai and Wenjun Lü, and Japan’s Hisashi Jogo (Avispa Fukuoka).

The 450th issue of the CIES Football Observatory Weekly Post analyses the game intelligence data produced exclusively by our partners SkillCorner to reveal the one hundred midfielders with the best statistics in terms of ball retention under high pressure* in 28 leagues around the world. The best percentage in absolute terms was recorded for a player who is relatively unknown in Europe: Darlington Nagbe (93.4%) of Columbus Crew.

Four better-known midfielders rank behind Nagbe: Rodri Hernández of Manchester City (92.1%), Frenkie de Jong of Barcelona (91.8%), Toni Kroos of Real Madrid (also 91.8%), and Granit Xhaka of Bayer Leverkusen (91.6%). Many footballers from teams playing a possession-based game are among the top-ranked ones, showing that the individual ability to keep possession also depends on the solutions offered by teammates.

The three youngest players in the top 100 are Paris St-Germain’s Warren Zaïre-Emery, Barcelona’s Pablo Gavi and Hull City’s Tyler Morton (on loan from Liverpool), followed by Gerard Yepes (Sampdoria) and Pablo Maia (São Paulo). The data refers to the current season or the last completed one for summer leagues. Only footballers who have played at least 1,000 domestic league minutes have been incldued in the rankings.

* A player is considered under pressure when he is in possession of the ball and at least one opponent player nearby him is trying to either recover the ball or limit his options. For each situation, SkillCorner determines the intensity of pressure by considering the speed of the players applying it, their distance to the player in possession and the angle of their movement.

The 449th CIES Football Observatory Weekly Post presents the 402 footballers who played in the big-5 before turning 18 during the 15-year period from January 2009 to December 2023. Italian goalkeeper Gianluigi Donnarumma is the footballer who has played the most minutes in the five major European leagues as a minor (4,879), followed by Alban Lafont, Eduardo Camavinga, Florian Wirtz, Pablo Gavi and Warren Zaïre-Emery (ongoing).

Seven players made their big-5 league debut before the age of 16, the youngest in absolute terms being Arsenal’s Ethan Nwaneri (15.5 years). With 119 minors fielded by their clubs, France’s Ligue 1 is the leader in this area, as the Monthly Report number 91 also reveals. The sharp rise in the use of underage players recorded since 2022 is strongly linked to the increase observed at French Ligue 1 level.

The study also shows that early experience in big-5 leagues is no guarantee of success. Only a minority (47.7%) of footballers used in the big-5 as minors and who subsequently played in other teams were able to do so for at least one club at a better sporting level than their initial one. This finding indicates that caution is required when it comes to assessing the true potential of players launched into professional football at an early stage.

The 448th CIES Football Observatory Weekly Post presents the 50 clubs in the world with the most positive and negative transfer balances for non-academy players signed and transferred between 2014 and 2023. The figures range from a positive balance* of €386 million for LOSC Lille (Pépé, Osimhen, Botman, etc.) to a negative balance of €631 million for Barcelona (Coutinho, Dembélé, Griezmann, etc.).

With +€317 million in capital gains, Ajax (de Jong, Antony, Lisandro Martínez, etc.) are in second place. RB Salzburg (Naby Keita, Mwepu, Haaland, etc.) complete the podium, just ahead of AS Monaco (Tchouaméni, Lemar, Bernardo Silva, etc.). The top 10 of clubs having generated the most profits from player trading during the last decade also includes two German (RB Leipzig and Eintracht Frankfurt), two Italian (Sassuolo and Atalanta) and two Portuguese teams (Benfica and Sporting CP).

At the other end of the scale, Barcelona (-€632 million) are ahead of Chelsea (-€482m with the three biggest losses for Jorginho, Pulišić and Rüdiger) and Arsenal (-€436m; Pépé, Aubameyang, Lacazette). Paris St-Germain has the fourth most negative balance (Neymar, Di María, Icardi, etc.), ahead of Manchester United (Matić, Fred, Mata, etc.). Manchester City (-€59m) and Bayern Munich (-€61m) have the best balances among the most competitive teams.

The 447th CIES Football Observatory Weekly Post presents the 100 centre backs in the world with the best aerial play statistics* according to an index computed from the number of aerial duels won, in relation to the playing time and the frequency of aerial duels at employer team level, the percentage of aerial duels won and the sporting level of the matches played. Liverpool’s Dutchman Virgil van Dijk is ahead of Bayern Munich’s South Korean Min-jae Kim.

Now reconverted from defensive midfielder to centre back, Paris St-Germain’s Portuguese Danilo Pereira rounds off the podium, ahead of two other players active in the five major European leagues: England’s Jamaal Lascelles (Newcastle United) and France’s Dan-Axel Zagadou (Stuttgart). Argentina’s Bruno Duarte (Panatelikos) is the highest-ranked player from outside the big-5, while Joaquim Henrique (Santos) tops the table for outside Europe’s centre backs.

Cerro Porteño’s Paraguayan Lucas Quintana is the youngest player in the top 100 (19.0 years of age, 95th), ahead of Westerlo’s, on loan from Galatasaray, Turkish Emin Bayram (20.8 years, 21st) and Chornomorets’ Ukrainian Volodymyr Salyuk (21.6 years, 42nd). By contrast, the three oldest centre backs in the top 100 are Sevilla’s Sergio Ramos (37.8 years, seventh), Racing Santander’s Germán Sánchez (37.1 years, 63rd) and Deportivo Saprissa’s Kendall Waston (36.0 years, 64th).

* Wyscout statistics refer to domestic league matches in the current season or the last completed one for summer leagues. Only footballers who have played at least 900’ are included in the rankings.

The 446th CIES Football Observatory Weekly Post presents the 100 clubs with the most profitable academies in the world in terms of revenues generated over the last ten years by the transfer of players who spent at least three seasons there between the ages of 15 and 21*. Portuguese side SL Benfica are clearly in the lead with €516 million, two thirds of which has been collected in the last five years.

AFC Ajax (€376 million) and Olympique Lyonnais (€370 million) complete the podium. As in the case of Benfica, the majority of Ajax’s revenues from the transfer of players from its academy has been generated over the last five years (66%). Despite transfer price inflation, this percentage is much lower for Olympique Lyonnais (50%).

Also in the top ten are three English clubs (Chelsea, Tottenham and Manchester City), a second Portuguese team (Sporting CP), as well as Real Madrid (fourth), AS Monaco (sixth, largely thanks to the revenues from Kylian Mbappé’s transfer to Paris St-Germain) and Italy’s Atalanta (tenth). Outside Europe, the clubs with the most profitable academies are Brazil’s Flamengo (thirteenth) and Argentina’s River Plate (fourteenth).

The 445th issue of the Weekly Post presents the 100 players in the world with the highest estimated transfer values according to the CIES Football Observatory statistical model*. English youngster Jude Bellingham (Real Madrid) tops the list with a transfer value of €267.5m, ahead of Norway’s Erling Haaland (Manchester City) and his two Brazilian teammates Vinícius Júnior and Rodrygo Goes.

As for the other leagues in the Europe’s big-5, Jamal Musiala (Bayern Munich) heads the rankings for the German Bundesliga, Khvicha Kvaratskhelia (SSC Napoli) for Italy’s Serie A and, despite a contract expiring in June, Kylian Mbappé (Paris St-Germain) for France’s Ligue 1. Outside the big-5, António Silva (SL Benfica) is ahead of Gonçalo Inácio (Sporting CP) and Endrick Felipe (SE Palmeiras, on loan from Real Madrid).

Compared to the estimates published last June, the number of players with a transfer value in excess of €100 million has almost doubled (from 20 to 39), reflecting the sharp inflation in player prices occurred during the summer 2023 transfer window. The value of the hundredth player with the highest estimated value is now €71.3 million, compared with €53.4 million in June 2023.

* Based on more than 6’000 paying fee transactions, the CIES Football Observatory statistical model allows us to accurately predict the transfer fees that clubs are likely to pay, given the prices invested in the past for players with similar characteristics. The estimates do not take into account eventual buy-out clauses. They refer to 100% of the economic rights and include both fixed and conditional sums (add-ons).

• Centre forwards: Rasmus Höjlund (2003), Manchester United, 88.9

All the rankings are available for free here. Thank you for your interest and happy holidays!

* Expressed on the basis of 100, the ’experience score’ was calculated from the number of official game minutes played at club (league, national cups, international cups) or national team (senior, U23 and U21) level in 2023 (limited to 2,250 minutes), the sporting level of the 25 most competitive matches in which the footballers took part (method available in this note), as well as the percentage of minutes played as first choice players.

The last CIES Football Observatory Weekly Post for 2023 ranks the clubs in 53 leagues around the world according to the average size of the line-ups fielded in the current or last completed season. Almost 13 centimetres separate the ‘tallest’ and ‘shortest’ teams: Hungary’s Kecskeméti TE (187.13cm) and Japan’s Sagan Tosu (174.18cm).

While Japanese clubs monopolise the bottom three places (Sagan Tosu, Albirex Niigata and Yokohama FC), three German clubs are in the top four positions: TSG Hoffenheim, FC Schalke 04 and FC Heidenheim. Rayo Vallecano is the only European big-5 league team with an average height on the pitch shorter than 180cm (178.61cm).

The world average is 181.46cm, with higher values in the UEFA association leagues (182.65cm) than in the other continents (179.54cm). All 55 teams where players over 185cm played a majority of minutes are from the Old Continent. More demographic data for 31 European top divisions are available in this Atlas.

Issue 443 of the CIES Football Observatory Weekly Post presents the exclusive data from our partners SkillCorner on the players* with record values in 40 competitions around the world for three indicators: distance covered, number of sprints during possession (>25 km/h for at least 0.7 seconds), as well as the same indicator during phases without the ball, in all three cases per 90’ of presence on the pitch.

In the European big-5, the following midfielders top the list in terms of distance covered per 90’: Sander Berge (Burnley FC), Koke Resurrección (Atlético Madrid), Daniel Boloca (US Sassuolo), Hugo Larsson (Eintracht Frankfurt) and Adrien Thomasson (RC Lens). When it comes to the number of sprints in the defensive phase, full-backs tend to come out on top, with the notable exception of the incredibly generous Heung-Min Son (Tottenham Hotspur) in the Premier League.

As for sprints in the offensive phase, the top spots notably include Nicolas Jackson (Chelsea FC) in the Premier League, the very promising Karim Konaté (RB Salzburg) in the Austrian Bundesliga, Sheraldo Becker (Union Berlin) in the UEFA’s Champions League, the Algerian arrow Mohamed Amoura (Union Saint-Gilloise) in the Europa League, Biel (EC Bahia) in the freshly terminated Brasilierão, as well as Agustín Canobbio (Athletico Paranaense) in the Copa Libertadores.

* To be included, players had to have played at least 720’ up to 7 December 2023 in national competitions and 360’ in international competitions.

Issue 442 of the CIES Football Observatory Weekly Post presents the footballers in the world who have played the most minutes in official matches (clubs as well as national U21- and A-teams) in 2023 up until December 4th. Topping the list in absolute terms is the Paraguayan centre back Gustavo Gómez of the Brazilian side Palmeiras, with 6,213 minutes in 70 matches.

Another Palmeiras player, Weverton Pereira (6,150 minutes in 68 matches), heads the rankings for goalkeepers active outside Europe, ahead of Rafael Monteiro from São Paulo, while the most-used goalkeeper playing for clubs in UEFA associations is Luxembourg’s Anthony Moris of Union St-Gilloise (5,590 minutes in 62 matches), ahead of KRC Genk’s Maarten Vandevoordt.

Among outfield players from European teams, the top three are Manchester United’s Portuguese Bruno Fernandes (5,748 minutes in 66 matches), Feyenoord’s Slovakian Dávid Hancko (5,248 minutes in 58 matches) and Real Madrid’s German Antonio Rüdiger (5,223 minutes in 63 matches). Thirty-five-year-old Dušan Tadić (Serbia and Fenerbahçe) is the oldest player in the top 10.

The 441st CIES Football Observatory Weekly Post crunches data from our partners Wyscout on shots attempted and goals scored during the current season to determine the best finishers* in 65 leagues on all continents. With 1.57 goals per 90’ and a conversion rate of 37% in relation to shots taken, Bayern Munich’s centre-forward Harry Kane tops the list.

Feyenoord’s Mexican striker Santiago Giménez is second (1.4 goals per game with a shot conversion of 33%), while Real Madrid’s England attacking midfielder Jude Bellingham and the new Congolese international from SC Braga, in Portugal, Simon Banza, are tied in third position. Also in the top 10 notably are Lautaro Martínez (fifth), Erling Haaland (seventh) and Kylian Mbappé (tenth).

Two players who have yet to celebrate their 19th birthday feature in the top 100: Roony Bardghji (18.0 years, 41st) of Copenhagen and Jayden Addai (18.9 years, 13th) of AZ Alkmaar’s second team. In contrast, the evergreen Óscar Cardozo (40.5 years, 30th) of Club Libertad, in Paraguay, is the oldest player in the top 100, ahead of Joaquín Larrivey (37.8 years, 23rd) of Deportes Magallanes, in Chile, and Cristiano Ronaldo (38.8 years, 56th).

*The finishing index is calculated by multiplying the number of domestic league goals scored per 90’ with the conversion rate of shots taken. The result is adjusted by the sporting level of the matches played (as a percentage difference from the overall average). Only footballers who have played at least 720 domestic league minutes for the same team during the current season are considered.

Issue number 439 of the CIES Football Observatory Weekly Post presents the 100 players in the world with the best statistics in terms of chance creation during the current season, according to an index* developed from Wyscout data. At the top of the list is Paris St-Germain’s winger Ousmane Dembélé. The Frenchman outranks Leroy Sané (Bayern Munich) et Nico Williams (Athletic Club)

Killian Mbappé (PSG) and Moussa Diaby (Aston Villa) also are in the top 5, while Federico Dimarco (Inter) and Kieran Trippier (Newcastle) are the top-ranked defensive players. The top three footballers who have not yet turned 21 are Florian Wirtz (Bayer Leverkusen), Johan Bakayoko (PSV Eindhoven) and Ilya Kvasnytsya (Rukh Lviv).

A total of 33 leagues are represented in the top 100, with a maximum of 16 players from the English Premier League, where Moussa Diaby (Aston Villa) is ahead of Mohamed Salah (Liverpool) and Bruno Fernandes (Manchester United). The top three in the second most-represented league, the Italian Serie A (nine players), are Federico Dimarco (Inter), Domenico Berardi (Sassuolo) and Felipe Anderson (Lazio).

* The creation index is calculated by adding the number of key passes (for chances) and expected assists (depending on the dangerousness of the chances created) per 90’, and weighting the result by the sporting level of the matches played (as a percentage difference from the overall average). Only footballers who have played at least 630 domestic league minutes for the same team during the current season are considered.

Issue 438 of the CIES Football Observatory Weekly Post combines SkillCorner’s physical and tactical (’game intelligence’) data with Wyscout’s technical ones to create a direct play index*. Based on 100, the latter allows us ranking teams from 27 leagues worldwide from those with the most direct attacking style to those with the most elaborated offensive play.

The highest values for direct play were recorded for Portugal’s SC Farense (100) overall, Luton Town (87) in the big-5, CA Banfield (83) for non-European teams, and Newcastle United (56) for UEFA Champions League participants. In contrast, the lowest values, reflecting the most elaborated attacking styles, were measured for two teams coached by Spaniards, Guardiola’s Manchester City (21) and Luis Enrique’s Paris St-Germain (23), with Arteta’s Arsenal (27) fourth.

Also presented in the Post, the extreme values for the specific variables of the index were observed for SC Farense (max) and SC Freiburg (min) regarding sprints during possession phases, Cercle Brugge (max) and Burnley (min) with regard to ‘call-for-the-ball’ runs into space, as well as Paris St-Germain (max) and FK Teplice (min) concerning the kilometres ‘covered’ by the ball also with the team in possession.

* The direct play index is calculated by multiplying the frequency of sprints per player (at least 0.7 seconds at over 25 km/h) during possession (projected over 90’) and the proportion of ‘call-for-the ball’ runs in space (SkillCorner data); divided by the number of kilometres ‘covered’ by the ball in possession, an indicator resulting from the multiplication between the number and average length of successful passes (Wyscout data).

The 89th CIES Football Observatory Monthly Report compares 48 leagues around the world according to the demographic characteristics of the players in the club’s first team squads: 31 top divisions of UEFA member associations, nine of CONMEBOL, six of AFC and two of CONCACAF. It reveals major differences in the strategies followed by clubs according to their geographical area.

In terms of age, the average measured across the 31 top divisions of UEFA associations is almost one year lower than that recorded in the 17 non-European leagues: 26 years compared to 27. With regard to the proportion of expatriates, the difference is almost 10%: 43.6% in Europe versus 23.8% elsewhere. These findings reflect the greater propensity of European teams to rely on young players, whether having grown up domestically or imported from abroad.

While the South American and Asian leagues tend to be similar both in terms of age, with relatively few young players, and origin, with comparatively few expatriates, they differ greatly in terms of squad stability. The proportion of players who have been with the club for less than a year is almost 10% higher in the nine South American leagues than in the six Asian championships analysed: 49.0% compared with 23.8%.

Also regarding stability, there are spatial specificities within Europe too, with fairly different levels emerging around a double polarity of West (more stability) – East (less) and North (more stability) – South (less). These geographical differences also reflect economic disparities, with the most competitive clubs tending to have a more stable workforce than the others.

According to the CIES Football Observatory’s 2023 survey on men’s professional club football, respondents believe that the fight against money laundering should be a top priority for regulatory bodies. More than six out of ten respondents (62.1%) consider indeed that action to counter money laundering through football is highly needed.

Fan racism (60.3%) and state-owned clubs (58.5%) are the other two areas where there is the strongest consensus that action is needed, followed by corruption (53.5%) and violence (51.8%). Almost one in two respondents also felt that action is highly needed in relation to commissions paid to agents and frauds in connection with transfer operations.

In contrast, of the 32 issues addressed, the three areas where respondents felt the least need for action are the quality of matches, their balance, as well as players’ aggressiveness. Among the societal issues surveyed, fan racism (action highly needed for 60.3% of respondents) is of greater concern than violence (51.8%), homophobia (42.1%) and sexism (29.0%).

The questionnaire was sent out in two languages to our subscribers, resulting in 1,100 valid responses. The main findings are published on our X/Twitter, Instagram and Facebook accounts or available on request.

Issue 437 of the CIES Football Observatory Weekly Post presents the top 100 dribblers* in the world among players who have not yet celebrated their 23rd birthday. FC Barcelona’s prodigy Lamine Yamal (2007) tops the rankings in the European big-5, while Club Brugge’s superb Norwegian talent Antonio Nusa (2005) heads the list in the other 65 leagues analysed.

At European big-5 league level, Lamine Yamal is ahead of Gabriel Martinelli (Arsenal), Luca Koleosho (Burnley), Khvicha Kvaratskhelia (Napoli) and Girona’s Sávio Moreira (on loan from Troyes, as part of the City Group galaxy). Also in the top 10 notably are Takefusa Kubo (Real Sociedad), Buyako Saka (Arsenal) and Frosinone’s young Argentinean talent Matías Soulé (on loan from Juventus).

Outside the big-5, behind Antonio Nusa, there are two Brazilian prodigies: Luis Guilherme (2006) of Palmeiras and Wesley Gassova (2005) of Corinthians. Two other U20 players are in the top 10: the Ghanaians Issahaku Fatawu of Leicester City (on loan from Sporting CP with an option to buy) and Ibrahim Osman of Nordsjælland.

* Calculated from Wyscout data, the index used was obtained by multiplying the frequency of successful dribbles in domestic league matches, the success rate of dribbles attempted, as well as the sporting level of the matches played (as a percentage deviation from the overall average). The rankings only include footballers who played at least 450 domestic league minutes in current season.

The 436th Weekly Post of the CIES Football Observatory presents the rankings of the teams that have trained* the most players active in 48 of the world’s major leagues (list in the Post). Ajax (86 players trained) is ahead of Benfica (85) and Sporting CP (83), while the Uruguayans of Defensor SC (82 trained) top the table among non-European teams ahead of Boca Juniors (81) and River Plate (79).

Ajax also has the highest score in the weighted training index (method in the Post), which takes into account the sporting level of the players trained. The Dutch team is ahead of Benfica and Barcelona, with Boca Juniors leading the table for non-European clubs ahead of city rivals River Plate. Two Ukrainian (Dynamo Kyiv and Shakhtar Donetsk) and a Croatian team (Dinamo Zagreb) are in the top 10 positions of the weighted table.

The Weekly Post also presents the rankings for players active in four league sub-categories: the European big-5, with Real Madrid in first place (44 players trained); 31 top divisions of UEFA associations, with Ajax at the top (84); eleven American leagues, with SC Defensor first (70); as well as six Asian leagues, with the Chinese of Shandong Taishan heading the table (37).

* Training clubs are those where players have been for at least three years between the ages of 15 and 21 (including the seasons of the 15th and 21st birthdays).

The 88th Monthly Report of the CIES Football Observatory analyses the brand new SkillCorner data on players’ run types during possession to classify the teams from 27 leagues worldwide according to the tendency of calling for the ball ‘at feet’ or ‘in space’. The study thus reveals the dominant strategies used by teams to organise attacking play.

Across the 27 leagues analysed, the highest proportion of ‘calls-for-the-ball’ runs into space (to receive the ball in front of the ball carrier) was measured in Mexico’s Liga MX, while the greatest percentage of ‘calls-for-the-ball’ runs at feet (to receive the ball mostly behind or laterally to the ball carrier) was recorded in Italy’s Serie A. At club level, the extreme values were observed for Cercle Brugge (‘in space’) and Burnley FC (‘at feet’).

Combined with physical data such as top speeds, number of accelerations or distances covered, SkillCorner’s ‘game intelligence’ statistics are very useful for clubs both on an individual and collective level. The possible applications range from defining a style of play and the tactical preparation of matches, the measurement of performance and its improvement, to recruitment choices and strategies.

The 435th CIES Football Observatory Weekly Post analyses the Wyscout data on passes to draw up a global ranking of the world’s top 100 midfield distributors* among those who played at least 450 domestic league minutes during the current season. The top three are Rodri (Manchester City), Frankie de Jong (Barcelona) and Toni Kroos (Real Madrid).

The top-ranked players outside the European big-5 are Aschraf El Mahdioui (Al-Taawoun, 6th), Álvaro Fidalgo (CF América, 8th) and Yahya Jabrane (Wydad AC, 10th). Two players who have not yet celebrated their 21st birthday rank in the top 100: João Neves of Benfica (34nd) and Eduardo Camavinga of Real Madrid (71th). Two footballers aged over 40 also feature in the top 100 places: Felipe Melo of Fluminense (38th) and Yasuhito Endo of Jubilo Iwata (77th).

* The index used takes into account the number of successful passes per match, the percentage of successful passes, the ratio of passes compared to teammates, as well as the average level of matches played. The methodology behind this last metric is explained in this note. Please do not hesitate to contact us for more information about our services.

The 434th CIES Football Observatory Weekly Post ranks 851 teams in 53 top divisions worldwide according to the average age of the line-ups fielded since the start of the current season. Values range from 20.97 years of age for FK Minsk of Belarus to 32.12 years for Independiente Petrolero of Bolivia. The average for all the clubs analysed is 27.24 years.

In the five major European leagues, the average age on the pitch ranges from 24.16 years for Toulouse FC to 30.19 for Rayo Vallecano. In the English Premier League, the extreme values were measured for Burnley FC (24.57 years), Chelsea FC (24.95) and Arsenal FC (24.96) on one side, and for Fulham (29.28 years) on the other.

The publication also presents the percentage of minutes by player age category (21 or under, 22 to 25, 26 to 29, and 30 or over). In eight teams, players aged 21 or under at the time of the matches played a majority of minutes. These notably include RB Salzburg (60.7%), FC Nordsjælland (56.1%) and AFC Ajax (53.3%).

Issue number 433 of the CIES Football Observatory Weekly Post presents an analysis of the data produced exclusively by our partner SkillCorner on the type of runs made by players when their team is in possession of the ball. Clubs from 27 leagues around the world are ranked according to the percentage of runs for short or backward passes*, highlighting the teams whose players like to receive the ball at their feet.

Raków Czestochowa’s players proportionally make the most runs for short or backward passes (31.1% of total runs). The Polish club is ahead of two European football giants: Manchester City (29.6%) and Paris Saint-Germain (28.5%). Eintracht Frankfurt (27.5%), Girona (26.5%) and AC Milan (25.9%) top the table in the other big-5 leagues. In absolute terms, the maximum runs for short or backward passes was recorded for Paris St-Germain (7.13 per match).

Using innovative tracking technologies, SkillCorner provides physical data for over 60 football leagues and competitions worldwide. Its new ‘Game Intelligence’ data focuses on the contextualisation of the game and notably includes ten categories of runs that can be used to qualify the style of play of teams and players, as we have done in this publication.

*Runs for short or backward passes are runs (>15 km/h for at least 0.7 seconds) made with the aim of offering a passing option to teammates, whether towards its own goal (‘drop off’) or to shorten the passing distance to the ball carrier (coming short).

The 432nd CIES Football Observatory Weekly Post analyses the rich data produced by our partners Wyscout to highlight the clubs that most dominate their opponents in 69 leagues across the world. The ranking is established on the basis of the average performance ratio with respect to opponents for four game actions: shots, shots from the box, passes and passes into the opponent’s third.

Levski Sofia tops the table with an average dominance ratio 3.31, ahead of another Bulgarian side, Ludogorets (3.26), Red Star Belgrade (2.99), Olympiacos (2.90) and Feyenoord (2.78). At the top of the rankings for the big-5 European leagues are Bayern Munich (ahead of Bayer Leverkusen), Naples (ahead of Inter), Paris St-Germain (ahead of LOSC Lille), Barcelona (ahead of Real Madrid) and Manchester City (ahead of Chelsea).

Outside Europe, the best ratios were recorded for two Saudi Pro League teams - Al-Hilal (2.29) and Cristiano Ronaldo’s Al-Nassr (2.13) – and Ecuador’s Independiente Del Valle (2.27). RB Bragantino (1.45) heads the table in Brazil, River Plate (1.92) in Argentina, CF América (1.60) in Mexico and New York RB (1.39) in the MLS. Over and above the rank currently occupied by the clubs, the dominance ratio helps in most cases understanding the position that teams can realistically hope to achieve.

Issue number 431 of the CIES Football Observatory Weekly Post ranks 70 leagues around the world according to the average duration of matches during the current or last completed season (Wyscout data). The overall average is 100’15’’, with a maximum of over 106’ in the top two Saudi competition levels.

The Spanish Liga is the competition where referees add the most injury time among the European big-5 (on average 13’03’’), ahead of the English Premier League (11’46’’) and the Italian Serie A (11’04’’). The lowest additional time value overall was recorded in the Finnish top flight (6’07’’), with less than 10% of fixtures lasting more than 100’.

Overall, the percentage of matches that last over 100’ is 52.4%. This proportion varies greatly between leagues: from 100% in the top division of the United Arab Emirates to just 6.7% in the Swiss second division. The share of games with a duration of over 100’ in the European big-5 stretches from 84.6% in Spain to 61.1% in France (71.8% in England).

The 430th edition of the CIES Football Observatory Weekly Post presents the top 100 teams in the world having invested the most on transfer fees (including add-ons regardless of effective payment) to recruit players currently in their squad. Four teams head the list with investments of at least one billion euros: three English clubs (Manchester United, Chelsea and Manchester City) and one French (Paris St-Germain).

Saudi side Al-Hilal (18th) is the club from outside the European big-5 that has invested the most on transfer indemnities to assemble its squad (€382m), ahead of Leicester City (26th, €281m) and Ajax (32nd, €236m). By position, the biggest spenders are Liverpool for goalkeepers (€73m), Manchester United for defenders (€383m), Real Madrid for midfielders (€447m) and Paris St-Germain for strikers (€557m).

Clubs from nineteen different leagues feature in the top 100, with a maximum of 19 teams for the English Premier League (all clubs except Luton), followed by the Italian Serie A (15 teams), the Spanish Liga (12), the French Ligue 1 (11) and the German Bundesliga (also 11). Among non-European competitions, the Saudi Pro League is the most represented (4 clubs), ahead of Mexico’s Liga MX (3) and Brazil’s Serie A (2).

CIES Football Observatory Weekly Post number 429 presents the net transfer spending* of the 100 most active clubs in terms of the financial volume of transactions concluded over the last decade. During this period, Manchester United has the most negative balance (-€1.396 billion), while the Portuguese side SL Benfica has the best (+€764 million).

Two other teams have had transfer losses of more than €1 billion over the last ten years: Chelsea and Paris St-Germain. Chelsea also has the most negative balances in the post-COVID period (-€993 million) and the calendar year 2023 (-€558 million). In contrast, SL Benfica outranks AFC Ajax (+€434m) and RB Salzburg (+€422m) over the last decade, while Villarreal CF has the most positive net spending in the 2023 calendar year (+€129m).

Also published today, the 87th CIES Football Observatory Monthly Report presents an even more detailed analysis of transfer-related financial flows in world football over the last decade. In particular, it shows that the amount of transfer fees incurred by clubs in 2023 (around €12.4 billion) was almost 25% higher than in the previous record year of 2019. This is essentially due to the sharp increase of English Premier League and Saudi Pro League clubs’ investments.

* The figures published include fixed transfer fees, any add-ons regardless of whether they have actually been paid, as well as sums invested in the context of paying loans. Amounts negotiated for loans with an obligation to buy are included in the breakdown for the year of the transfer. Within the limits of available information, the data on beneficiaries considers sell-on fees negotiated by previous clubs.

Issue number 428 of the CIES Football Observatory Weekly Post presents the 100 players born in 2002 or later who are not yet playing for a big-5 league club, but whose level of experience accumulated over the past year puts them in the best position to successfully take their careers to the next level.

Born in 2003, "air-ground blocker" António Silva (SL Benfica) is the player best equipped to join a top club. His transfer value is estimated at €102.5 million by the CIES Football Observatory statistical model. The Portuguese is ahead of two players born in 2002, "ground-air blocker" Pablo Maia (São Paulo FC, €17.4m) and "shooter-creator" Georgiy Sudakov (Shakhtar Donetsk, €35.6m).

Barcelona’s new recruit Vitor Roque (Athletico Paranaense, €53.5m) is in fourth place, an impressive ranking for a player born in 2005. Arthur Vermeeren (Anverse, €10.2m) and Jorne Spileers (Bruges, €7.2m) are the only other footballers born in 2005 in the top 100, compared with ten born in 2004, the highest-ranked of whom is the Moroccan full international Bilal El Khannouss (KRC Genk, 14th, €20.6m).

Exclusively developed by the CIES Football Observatory research team, the 100-based experience capital metric is particularly useful for scouts, as it enables them to rank players by considering both their playing time and the sporting level of matches played. This makes it easy to identify the talents whose recruitment offers the best guarantees of success.

A paying platform with numerous statistical indicators has been developed to help professionals optimise their strategies. More information is available on request.

Issue 427 of the CIES Football Observatory Weekly Post ranks the teams in 69 leagues around the world according to the average experience level of players in the squad. Experience is calculated by weighting minutes played in official club or national team matches over the last year by the sporting level of the games, with a maximum possible value of 100.

For the European big-5, Manchester City (85.6 and 63.2), Real Madrid (82.5 / 60.6), Bayern Munich (73.4 / 52.3) and Paris St-Germain (67.9 / 48.5) have the highest values for both ‘starters’ (i.e. the eleven most experienced players) and ‘substitutes’ (up to the next eleven). In Italy, Inter and Napoli are tied for the first (72.7), while Fiorentina leads the way for the second (47.6). The Tuscans could therefore be the surprise package of the season.

In Argentina, River Plate are first for the ‘starters’ and Boca Juniors for the ‘substitutes’. In Brazil, surprise leaders Botafogo are behind Palmeiras, Flamengo and Fluminense. In MLS, Messi’s Inter Miami have the most experienced starters, while Philadelphia Union have the best bench. In Turkey, Fenerbahçe are expected to take the title from Galatasaray, while Benfica should retain their crown in Portugal, as should Al-Ittihad in Saudi Arabia.

With a new final phase of the FIFA World Cup to come, women’s football continues its development worldwide. The June’s CIES Football Observatory Monthly Report analyses the composition of squads of the eight clubs having reached the quarter-finals of the 2022/23 UEFA Women’s Champions League.

Footballers under 23 years of age only accounted for 16.8% of minutes played by the UEFA Champions League quarter-finalists. This finding reflects the difficulty for young talents in establishing themselves in the top European clubs. The highest level was recorded for the unfortunate finalists, Wolfsburg (26.3%), which indicates a bright future for the German club.

Almost half of the minutes in the quarter-finalists were played by expatriate footballers. Particularly high levels were recorded for the two English teams present at this stage: Arsenal (83.2%) and Chelsea (74.5%). However, the two finalists, Wolfsburg (30.9%) and Barcelona (35.5%), are at the opposite, which shows that it is still possible to achieve the highest results with a majority of national players.

With 77 expatriates, the double World Cup title holders of the United States are the top exporting country for players active abroad in the ten principal women’s leagues, ahead of Sweden (48 expatriates), Denmark (45) and Canada (44).

Issue number 425 of the Weekly Post presents the top 100 estimated transfer values using the statistical model exclusively developed by the CIES Football Observatory. Manchester City and Premier League top scorer Erling Haaland heads the list with a value of almost €250 million (eventual buy-out clause not considered). Two other footballers under 23 years of age, Vinícius Júnior and Bukayo Saka, who just extended his Arsenal’s contract, complete the podium.

Rumoured close to Real Madrid, Borussia Dortmund’s teenager Jude Bellingham is fourth with an estimated value of €190 million (eventual add-ons included as for all players listed). The Englishman outranks Rodrygo Goes and the FC Barcelona’s duo Pedri González and Pablo Gavi (assuming that the registration of his contract until 2026 will be effective). Jamal Musiala, Phil Foden and Kylian Mbappé (contract with PSG until 2024 only) complete the top 10 list.

The highest estimated values for players from outside the big-5 were recorded for two Portuguese top talents: António Silva (€89 million) and Gonçalo Ramos (€82 million). The SL Benfica’s duo are ahead PSV Eindhoven’s Xavi Simons, FC Porto’s Diogo Costa, Sporting CP’s Gonçalo Inacio and three AFC Ajax players. More information on the statistical model used is available in this scientific paper. Evaluations for more than 30,000 players in 75 leagues around the world are available via a paying platform.

Issue number 424 of the CIES Football Observatory Weekly Post defines the attacking styles of teams from 23 leagues worldwide on the basis of the data on players’ high intensity runs exclusively produced by SkillCorner (>20km/h for at least 0.7 seconds). For each league, clubs are ranked from those whose players perform more in-possession high intensity runs than expected with respect to the minutes of possession to those who perform less.

A positive gap is characteristic of teams tending to go rapidly forward, while a negative gap is typical of teams building-up in a more horizontal way. Most of the dominant teams are in the second category, notably Shakhtar Donetsk (-12.1%), Paris St-Germain (-10.9%) and Manchester City (-8.2%), but RC Lens (+10.1%), Newcastle United (+8.5%) and Borussia Dortmund (+6.0%) show that it is possible to obtain top level results with a more vertical attacking style.

SkillCorner’s pioneering tracking technologies use broadcast and tactical video to deliver physical and contextual data for more than 60 football leagues and competitions across the world. Its standardised physical data allows users to benchmark and track the physical attributes of players, teams and leagues by supporting decision making on scouting, recruitment, player development and team strategy. The data includes a large set of metrics, including the "Count of High Intensity runs" used here.

Issue number 423 of the CIES Football Observatory Weekly Post ranks 60 top division leagues around the world according to the percentage of coaches in place at the start of the 2022/23 season who are no more in charge today. Of the 850 teams analysed, 484 changed coaches during the season, corresponding to a percentage of 56.9%.

The greatest percentages were measured in three leagues from the former Yugoslavia (Bosnia, North Macedonia and Serbia), followed by one from Central America (Costa Rica) and two from Africa (Algeria and Tunisia). At the other end of the scale are India (just one coach replaced in 11), Malta (3 in 14) and Australia (3 in 12). For the big-5, the values range from 55% in the Premier League (11 out of 20) to “only” 35% in Serie A (7 out of 20).

Clubs that changed coach at least once made the first replacement on average after 45.4% of matches, with a negative record of only 24.6% of games led by the coach who started the season in Romania, followed by the United Arab Emirates and Greece. In the big-5, the values stretch from 56.6% in the English Premier League to 35.6% in the Italian Serie A, where clubs changed relatively few coaches but rather quickly.

The 422nd edition of the CIES Football Observatory Weekly Post presents the ranking of the 100 associations with the highest number of expatriate players in 135 leagues worldwide. With a record number of 1,289 expatriates, Brazil tops the list ahead of France (1,033) and Argentina (905). Nigeria, Japan and the United States heads the rankings for the other main confederations.

The Post also presents the number of expatriates by age group, with the French in first place for those aged 23 or under, Brazilians for those aged 23 to 26 and 27 to 30, and Argentinians for those aged over 30. More detailed analyses including changes measured since 2017, with record increases for France and Colombia, are available in the 85th Monthly Report.

Expatriates are defined as footballers playing outside the association where they grew up, which they left following recruitment by a foreign club. This definition makes it possible to isolate sports migration from ordinary one, thus highlighting the flows directly linked to the practice of football. The Migration Atlas presents the main destinations for football migrants of all origins.

The 421st Weekly Post presents the player with the highest transfer value according to the CIES Football Observatory statistical model for 1,229 clubs in 74 leagues around the world. For each player, we also present the proportion that its value represents with respect to the total value of all footballers under contract with his owner club.

The highest values for the four Champions League semi-finalists were recorded for Erling Haaland at Manchester City (>€200m), Vinícius Júnior at Real Madrid (>€200m), Lautaro Martínez at Inter (>€80m) and Rafael Leão at Milan (>€60m). Among other players heading the table for their respective clubs notably are Bukayo Saka (Arsenal), Pedri González (Barcelona), Jamal Musiala (Bayern), Pedro Guilherme (Flamengo) and Alan Varela (Boca Juniors).

We are also proud to launch a new tool providing access to the estimated value of more than 30,000 professional players worldwide under a scenario with a contractual duration of at least three years. Vinícius Júnior (>€250m), Kylian Mbappé (also >€250m) and Erling Haaland (>€200m) are in the top three positions of this virtual ranking. Gianluigi Donnarumma tops the table for goalkeepers, Éder Militão for centre backs, Reece James for full backs and Jude Bellingham for midfielders.

The 420th edition of the CIES Football Observatory Weekly Post uses Wyscout data on dribbling in domestic league matches over the last 365 days to compile a world ranking of the best dribblers according to an index combining the frequency and percentage of successful dribbles, as well as the sporting level of teammates and opponents. Only footballers who have not yet turned 23 and have played at least 1’500 domestic league minutes are included.

Real Madrid’s Brazilian winger Vinícius Júnior tops the list with a successful dribble every 15 minutes and 32 seconds, and a success rate of 50.3% in highly competitive matches. His compatriot Ângelo Gabriel of Santos FC ranks second with even more impressive statistics, albeit in lower-level games: one successful dribble every 13 minutes and 56 seconds with a 64.2% success rate. Bayern Munich’s Jamal Musiala rounds up the podium ahead of AFC Ajax’s Mohammed Kudus.

Players from 35 different leagues are in the top 100, with Spain’s La Liga in first place (11 representatives), one more than the English Premier League and Argentina’s Liga Profesional. Born on 23 December 2004, Brighton & Hove Albion’s Facundo Buonanotte is the youngest player in the top 100, followed by Ângelo Gabriel (born just two days earlier), RB Salzburg’s Israeli Oscar Gloukh and Vélez Sarsfield’s Julián Fernández.

Issue 419 of the CIES Football Observatory Weekly Post lists the 200 U20 players in 75 leagues around the world (20 in each of the ten positions considered) who have accumulated the most official game experience during last year. The highest score overall was recorded for Barcelona’s prodigy Gavi, whose relative experience capital is 4.37 times higher than the average measured for players of the same age and position.

The top players by position are Plamen Andreev (Levski Sofia, goalkeeper), António Silva (Benfica, centre back), Alejandro Balde (Barcelona, left back), Rico Lewis (Manchester City, right back), Arthur Vermeeren (Royal Antwerp, defensive midfielder), Pablo Gavi (Barcelona, central midfielder), Bilal El Khannouss (KRC Genk, attacking midfielder), Matheus Martins (Watford, left winger), Ângelo Gabriel (Santos, right winger) and Marcos Leonardo (Santos, centre-forward)

The ranking was established according to the experience capital method, taking into account the minutes played in official games during the last 365 days, the sporting level of the matches and the results. Furthermore, the experience capital was related to the average measured for players of the same age and position, which allows us to present a relative score as mentioned above.

The 418th edition of the CIES Football Observatory Weekly Post ranks 75 leagues around the world according to the frequency of penalties awarded by referees since 1 January 2020. The Egyptian Premier League heads the rankings with a penalty whistled every 172 minutes (not including injury time) compared to a global average of 271 minutes.

At the other end of the scale are the Japanese J1 League (every 520 minutes) and J2 League (every 613 minutes), as well as the English Championship, League One and League Two. In terms of conversion rates, the world average is 77.1%.

The 84th CIES Football Observatory Monthly Report analyses attacking playing styles adopted by clubs in 75 leagues worldwide using data for no less than 18,000 matches collected by InStat (now Wyscout). The team statistics on counter-attacks were combined with those of passes in the opponent’s third to distinguish four different offensive styles of play.

The “pressure” style favouring positional attacks is notably predominant il all big-5 leagues except the Bundesliga. The “alternance” style mixing positional and fast attacks is the dominant one notably in the Belgian and Turkish top divisions. The “waiting” style with below-average values for both counter-attacks and last third passes is the main one in both Germany and Portugal, while the “projection” style favouring quick attacks is notably widespread in Latin America.

The team analysis allows for a more precise definition of the offensive tactical options adopted by individual clubs. Although to different degrees, the majority of the most competitive teams adopt a “pressure” attacking style. However, there are exceptions such as Liverpool and Borussia Dortmund who fall into the “alternance” category, Roma and Juventus adopting a “waiting” style or Milan and Eintracht Frankfurt practising a “projection” one.

Finally, we would like to thank the people at InStat for having facilitated access to their data and having understood the meaning of our approach and our mission to push back the frontiers of knowledge in the service of the sustainable development of football around the world. We are sure that our many regular readers will join us in thanking them.

Issue number 415 of the CIES Football Observatory Weekly Post ranks 76 leagues worldwide according to the number of cards per match handed out by referees since 1 January 2020. Bolivia’s Primera División tops the list (7.01 cards per game with 0.55 reds), while Japan’s J2 and J1 leagues are at the opposite end of the spectrum (1.99 cards per match with just 0.05 reds).

Seven Latin American leagues rank in the top nine in terms of total number of penalty cards, the only exceptions being Portugal’s Primeira and Segunda Liga. At the opposite end, Japan’s top two divisions are ahead of the top two leagues from the Netherlands. England’s Premier League Championship, League One and League Two are also at the bottom of the table, confirming the low propensity of referees across the Channel to issue penalty cards.

Issue 414 of the CIES Football Observatory Weekly Post ranks 126 associations worldwide according to the average age of their senior men’s national team line-ups fielded in the last year. The maximum was recorded for Kuwait (29.76 years), while the minimum was observed for Bahamas (22.82 years). In Europe, the values range from 29.40 years for Belgium to 25.07 years for Turkey.

The three lowest values among last FIFA World Cup participants were measured for the USA (24.74 years), Ecuador (25.78 years) and Ghana (25.97 years). All three selections have a bright future ahead. Overall, the share of minutes of players aged 21 or under is 10.2%, compared to 32.7% for 22-25 year olds, 31.5% for 26-29 year olds and 25.6% for 30 year olds or over.

The loan of players is a practice much in vogue in professional football. The 83rd edition of the CIES Football Observatory Monthly Report analyses the characteristics of 3,178 players currently on loan in 75 leagues from 57 associations worldwide. It notably shows that loans concern 9.5% of players, with record percentages at around 20% in Italy.

The report also highlights that loans do not just involve footballers at the start of their career. Indeed, less than 30% of the total number of players on loan are 21 years of age or under, while almost half are 24 or over. This shows that loans are not uniquely used with the aim of developing the potential of young players, but also for several other reasons, such as making room in squads or signing reinforcements without paying transfer indemnities.

Many big-5 league teams figure among the clubs who loan out the most players present on the 1st March in the 75 leagues analysed. Arsenal tops the list with 25 footballers loaned out, followed by Atalanta. Inter, Brighton & Hove Albion, Manchester City, Juventus, Chelsea and Wolverhampton also are in the top 10. Generally speaking, the more competitive the club, the more it tends to loan out players to other teams.

In 63.5% of cases, the clubs where players are loaned have a lower sporting level to the owner clubs. This result indicates that loans principally serve the interests of the wealthiest teams, by allowing them to control the career of more players than they could have in their squad and develop. The club multi-ownership strategy, increasingly used by dominant teams, only reinforces this process.
