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.
