Issue number 254 of the CIES Football Weekly Post investigates InStat data to present the 20 clubs with the highest and lowest percentages of shots on target both in the five major European leagues and in 25 other domestic championships. The figures vary from 48.6% (Manchester United) and 28.9% (Cagliari) in the big-5, as well as from 50.4% (Ajax) and 31.7% (four different clubs) in the other competitions surveyed.

The study also presents the average distance of all shots attempted. The lowest values for clubs ranked in the top 20 tables were recorded for Bayern Munich (15.8 meters) in the five major European leagues and for the Dutch side PSV Eindhoven (also 15.8 meters) at the level of the remaining 25 leagues surveyed. Generally speaking, the higher the percentage of shots on target, the lower the distance from which they are taken.

The average percentage of shots on target for all clubs in the leagues studied is 37.6% (from 41.2% in the Dutch Eredivisie to 35.0% in the Russian Premier League), while the general shot distance is 18.5 meters (from 17.4 meters in the English Premier League to 19.5 meters in the Serbian Super Liga). More pitch statistics at club level are available in the freshly updated CIES Football Observatory Performance Atlas.

Weekly Post number 253 presents the aggregated transfer value of big-5 league clubs. According to the algorithm exclusively developed by the CIES Football Observatory, the estimated value of the squad of five teams is over one billion euro. Four of them are from the Premier League, which reflects the financial power of the English top division. Barcelona is the best-ranked non-English team.

The total transfer value of Manchester City players is almost €1.5 billion. This figure is one time and a half higher than the transfer fees spent to assemble the squad. However, this capital gain is only hypothetical insofar a team like Manchester City wants to win trophies rather than releasing its best footballers. In addition, within the current inflationary context, possible replacements are far more expensive than their predecessors.

The squad transfer value of four teams in the top 40 positions of the table is more than three times greater than the sums spent in transfer indemnities to recruit current players: Olympique Lyonnais (15th, x3.3), Real Sociedad (31st, x3.4), LOSC Lille (37th, x3.2) and Real Betis (38th, x3.1). Well-established in the top division league of their country of belonging, these clubs have an equally well-established business model relying on the promotion of talents. The estimates for all big-5 league players are available on the CIES Football Observatory website.

Issue number 252 of the CIES Football Observatory Weekly Post relies on OptaPro data to rank big-5 league footballers according to the number of domestic league minutes played per successful dribble over the last 365 days. Lionel Messi heads the rankings with a dribble achieved every 19.2 minutes, ahead of Allan Saint-Maximin (19.8) and Eden Hazard (21.0). The analysis only includes footballers who played at least 1,800 minutes (1,500 for current Bundesliga players).

Five players who grew up in France are in the top 8 positions: Allan Saint-Maximin, Naïm Sliti, Ousmane Dembélé, Marcus Thuram and Jeff Reine-Adelaide. The young English prodigy Jadon Sancho is the best-ranked player of those currently playing in the Bundesliga ahead of Ihlas Bebou and teammate Achraf Hakimi. Paulo Dybala heads the rankings for Serie A footballers ahead of Rodrigo de Paul and Federico Chiesa.

The Belgium and Chelsea striker Eden Hazard has the best success rate among players who attempted at least 100 dribbles during the period considered (73%). Three other players had a success rate of more than 70%: Naïm Sliti, Marcus Thuram and Éver Banega. At the opposite end of the table are Roberto Pereyra (43%), Fabián Orellana (44%) and Joshua King (also 44%). This unique tool exclusively developed by the CIES Football Observatory allows you to compare the technical profile of big-5 league footballers.

Issue number 251 of the CIES Football Observatory Weekly Post highlights the 20 most experienced young players from 22 European competitions per year of birth. The rankings were elaborated using an exclusive methodology weighting domestic league minutes played by footballers during the last two years according to the sporting strength of employer teams.

St-Étienne’s centre back William Saliba tops the table for players born in or after 2001. He outranks another French centre back, Benoît Badiashile (Monaco), and the Spaniard Bryan Gil (Sevilla). Two English players head the rankings for players born in 2000: Ryan Sessegnon (Fulham) and Jadon Sancho (Borussia Dortmund). Heerenveen’s talent Kik Pierie ranks third ahead of Real Madrid’s rising star Vinícius.

Gianluigi Donnarumma (Milan) is clearly at the top of the 1999-born players. He outranks the Dutch prodigy Matthijs de Ligt (Ajax) and another goalkeeper: Alban Lafont (Fiorentina). World champions Kylian Mbappé (Paris St-Germain) heads the table for players born in 1998, ahead of compatriot Houssem Aouar (Olympique Lyonnais) and Liverpool’s full back Trent Alexander-Arnold.

The CIES Football Observatory celebrates the 250th edition of its Weekly Post with an exclusive analysis on the contribution of clubs in training the players fielded in big-5 league matches during the last five years. Training clubs are those where players have been for at least three seasons between the ages of 15 and 21. The rankings are elaborated by summing minutes played in the big-5 since January 1st 2014 by all of the footballers trained per club.

Barcelona tops the table with 69 footballers trained fielded in the big-5 by 55 different teams for a total of 319,224 minutes. Behind the Catalans are their great rivals Real Madrid: 69 footballers trained, 44 different clubs, 304,052 minutes. In the top ten positions are six Spanish, three French and one English team (Manchester United). According to the definition used, Cristiano Ronaldo and Paul Pogba are Manchester United club-trained players.

The best-ranked clubs for the remaining big-5 leagues are Olympique Lyonnais, VfB Stuttgart and AS Roma. The greatest contributors outside of the countries hosting the five major European competitions are River Plate, Sporting Clube, Boca Juniors, Ajax and Feyenoord. In total, 1,370 teams have trained players fielded in the big-5 during the last five years. More information is available on request at football.observatory@cies.ch.

The 42th Monthly Report of the CIES Football Observatory analyses the evolution of the competitive balance in the group stages of the UEFA Champions League since the introduction of the current format in 2003/04. The study illustrates a clear trend towards less balance and more predictability. Changes in the competition format and the redistribution of resources are needed to preserve a sufficient level of sporting and economic balance.

The analysis of the distribution of points at the end of the group stages shows that teams at the top of the table have progressively obtained more points and significantly improved their goal difference. The opposite trend was observed for teams at the bottom of the group. The average goal difference in group stage matches also increased. This is notably linked to the growth of fixtures which concluded with at least a three goal difference: from 16.9% during the first four seasons analysed to a new record of 22.9% between 2015 and 2018.

The study also reveals the greater predictability of matches. The percentage of fixtures where teams that are clear favourites according to odds on the betting market go on to win went clearly up: 81.4% of wins at home between 2014 and 2018 (+5.3% in comparison to 2004-2008) and 74.6% away (+12.1%). A good compromise to preserve the interest of the Champions League over the long term would consist of reducing the number of participants in the group stage, while keeping an open system of competition and guaranteeing a greater percentage of revenue to those excluded.

Solidarity could operate through a meritocratic basis by keeping aside part of the revenues for all of the teams having participated in the training of players fielded. Such a redistributive mechanism would have the great merit of recognising the fundamental role played by a multitude of clubs in developing the players who guarantee the high quality spectacle that the major teams produce and from which they derive benefit. Go to the study here.

Who are the footballers having played the most minutes in the big-5 leagues during the last five years? This is the question answered in issue number 249 of the CIES Football Observatory Weekly Post. Samir Handanovi? (Inter) tops the table for goalkeepers, while César Azpilicueta (Chelsea) heads the rankings for outfield players.

Only ten goalkeepers in the top 25 list have been in the same club during the last five years. This is the same proportion as that observed among outfield footballers. Conversely, Joe Hart played for four different big-5 league teams over this period: Manchester City, Torino, West Ham and Burnley. Only five forwards are in the top 25 list: Lionel Messi, José Callejón, Romelu Lukaku, Luis Suárez and Antoine Griezmann.

The most fielded players at German Bundesliga level, where there are fewer matches as only 18 teams are competing, are Daniel Baier (13,477 minutes for Augsburg) and Oliver Baumann (15,210 minutes for Freiburg and Hoffenheim).

No team in the 35 European competitions surveyed needed as few shots to score as Paris St-Germain. The French side scored so far every 4.7 shots. According to the exclusive InStat data, this ratio was inferior to five for another big-5 league club only: Borussia Dortmund. The top three per league is available in issue number 248 of the CIES Football Observatory Weekly Post.

The most efficient teams in the three remaining leagues of the big-5 are Barcelona (5.4 shots per goal), Arsenal (5.8) and Sampdoria (5.9). The highest figure among teams from the five major European leagues was recorded for Huddersfield Town: 17.3 shots per goal. The Premier League club must absolutely improve this statistics to avoid relegation.

The most efficient team outside of the big-5 are the Swiss of BSC Young Boys (4.8), ahead of FC Midtjylland and PSV Eindhoven. On the contrary, Apollon Smyrnis (25.1), Hapoel Tel Aviv (21.1) and Arsenal Kyiv (20.7) were so far particularly inefficient. More data is available in the CIES Football Observatory Performance Atlas, as well as on demand.

Issue number 247 of the CIES Football Observatory Weekly Post presents big-5 league players whose current estimated value exceeds the most the fee paid by recruiting teams during last summer. Rodri Hernández (+€45 million) tops the table for fee-paying transfers ahead of Lucas Torreira (+€44m), while Emre Can (+€45m) heads the rankings for free agents ahead of Stefan de Vrij (+€39m).

Juventus and Liverpool are the only teams with three recruits in the top 20 tables: Emre Can, Cristiano Ronaldo and João Cancelo for the former club, as well as Xherdan Shaqiri, Alisson Becker and Fabinho Tavares for the latter one. The excellent performances of both these players and their employer teams explain in large part the magnitude of the gap observed.

Seven other clubs have more than one representative in the top 20 lists: Inter Milan (de Vrij and Asamoah), Napoli (Younes and Ruiz), Real Betis (López and Canales), LOSC Lille (Bamba and Ikoné), Everton (Bernard and Richarlison), West Ham (Wilshere and Anderson) and Arsenal (Torreira and Guendouzi). Current values were estimated using the exclusive CIES Football Observatory algorithm.

The 41st CIES Football Observatory Monthly Report analyses the link between ball possession and results in 35 European leagues. While this link is undeniable, it is only from a certain level that ball control allows teams to improve significantly their results. This is probably the source of the erroneous but widespread idea that possession is not a key factor for success.

The 70 champions of the last two seasons in the 35 leagues analysed had an average possession of 57% during their winning season. Only 10% of champions won their league with a ball possession of less than 50%: Spartak Trnava, RC Strasbourg, Stade de Reims, AIK Solna, FC Midtjylland, Spal 2013 and CFR Cluj. None of the 70 champions completed fewer passes in the attacking third of the pitch than their opponents during the title winning season.

The analysis at match level for all the possession indicators taken into account shows that a team can sometimes accept an opponent’s domination, especially when they are winning. However, this is not a successful strategy in the longer term as it implies too many risks of conceding the first goal without being then able to put sufficient pressure on opponents. The data used were generated by the specialist sports company InStat. More information is available on demand.

Issue number 246 of the CIES Football Observatory Weekly Post analyses the pitch production of big-5 league clubs during the first part of the current season to highlight if they have over- or under-performed in terms of points achieved. The findings suggest that Manchester City will finally beat Liverpool in the English Premier League title race.

Manchester City achieved so far 5% of points per match less than expected according to its pitch production. Conversely, Liverpool obtained 15% more and its results are supposed to decline in the second part of the season. The over- or under-performance were calculated according to a regression model built on the 2016/17 and 2017/18 seasons including shots on target, ball possession and shots conceded from the box. The data comes from the specialist company InStat.

In the other big-5 leagues, the pitch production of three out of four teams at the top of the table should allow them to lift the trophy: Barcelona in Spain, Juventus in Italy and Paris St-Germain in France. However, in Germany, the analysis suggests that Bayern Munich will finally outrank the current leader Borussia Dortmund. The data for 27 further European competitions are available on demand. More data is also accessible in the exclusive CIES Football Observatory Performance Atlas.

The first Weekly Post of the year presents the 100 big-5 league players with the highest transfer value according to the exclusive CIES Football Observatory algorithm. The 20-year-old French prodigy Kylian Mbappé (€218.5 million) tops the list ahead of Harry Kane (€200.3m) and Neymar (€197.1m).

Among the 27 footballers with an estimated value of more than €100m, sixteen play in the Premier League, five in the Liga, three in the Serie A, two in the Ligue 1 and one in the Bundesliga. Eleven nations have representatives with an estimated value of more than €100m: Brazil (6 players), England (5), France (5), Argentina (2), Portugal (2), Belgium (2), Egypt (1), Germany (1), Senegal (1), Uruguay (1) and Italy (1).

The transfer values for all big-5 league players are available online. A research note explaining the methodology used by the CIES Football Observatory and the criteria included in the algorithm is accessible here. Please contact us for more information and consultancies.

The last CIES Football Observatory Weekly Post of the year 2018 highlights players whose teams have achieved the most or least points per match when they were in the starting 11 than when this was not the case. The most positive gap in absolute was recorded for Christophe Jallet (OGC Nice): 7 wins out of the 7 matches that he started compared to only 0.44 points per match for the remaining games.

In the other big-5 leagues, the most positive gaps for players who have been present or absent at least five times in the starting 11 were recorded for Diogo Jota (Wolverhampton), Rubén Rochina (Levante), Andreas Beck (Stuttgart) and Goran Pandev (Genoa). Pedro Rodríguez and Ross Barkley were so far also lucky carriers for Chelsea: 100% of points for matches started in both cases.

Conversely, the most negative gaps per championship were registered for Massimo Gobbi (Parma), Gerard Gumbau (Leganés), Denis Zakaria (Borussia Mönchengladbach), Anthony Knockaert (Brighton & Hove) and Olivier Boscagli (OGC Nice). However, it is useful to remind that these results are in part a random fact.

The CIES Football Observatory is pleased to announce the launch of a parallel research group within the Centre International d’Étude du Sport (CIES). Led by Fernando Roitman, this new team focuses on aspects of sports governance, finance, legal and development.

The freshly published ‘Governance Structures at National Association Level’ report focuses on a selection of 20 countries from all six confederations and provides insight into one of the crucial aspects of world football. The study analyses five main areas: General Assembly (GA), Executive Committee (ExCo), President, judicial bodies and reporting activities. As findings are standardised in their form, the document allows benchmarking between individual case studies and the identification of potential trends across different regions of the world.

Issue number 243 of the CIES Football Observatory Weekly Post presents the top 20 tables for big-5 league players whose transfer values have increased the most during the last three months both in absolute and relative terms. At the head of the two rankings is the fresh English full international and Borussia Dortmund player Jadon Sancho: +€78 million and +806%.

Apart from Sancho, four players have seen their transfer value increase by more than €30M: João Cancelo (Juventus), Andrew Robertson (Liverpool), Richarlison (Everton) and Thilo Kehrer (Paris St-Germain). Many hot prospects are in the top 20 list of players whose value has risen the most in relative terms. The highest figures per league were recorded for Jadon Sancho in Germany, Moise Kean in Italy, Stanley N’Soki in France, Isaac Success in England and Júnior Firpo in Spain.

This analysis was performed using the exclusive CIES Football Observatory algorithm. A detailed explanation of the approach developed is available in this research note. The transfer value of all big-5 league players is freely accessible on the CIES Football Observatory website. The figures published refer to the estimated price for the most likely recruiting club. Moreover, a calculator was developed to allow users assessing the transfer value of players worldwide. However, this tool only provides rough estimates. Deeper analysis is available on demand.

The 40th Monthly Report of the CIES Football Observatory analyses the evolution of competitive balance in 24 European leagues over the last 10 seasons. The study reveals a clear trend towards a greater imbalance. The level of imbalance is particularly marked and on the increase in the big-5 leagues and the Champions League, where the economic divides between teams are very strong.

In 2017/18, big-5 league champions achieved a record of 83.3% of points. This proportion is 10% greater than that measured in 2008/09. Over the ten seasons studied, the biggest average goal difference per match was measured for the UEFA Champions League: 1.58 goals. The premier competition of European football is also that presenting the highest proportion of matches with a goal gap of at least three: 21.0%.

According to the Report, “the concentration of resources goes hand in hand with the concentration of talents. Many teams and leagues are confined to a stepping-stone role for up and coming players. This permits the generation of profits on the transfer market. However, the financial compensations from these transactions are not sufficient to halt the increasing competitive imbalance. The present situation favours the wealthiest clubs. Each day, they increase their sporting, economic and political domination”.

Issue number 242 of the CIES Football Observatory Weekly Post relies on InStat data to present the average effective time of games in 37 European competitions. The Swedish Allsvenskan is the league with the most fluid matches (60.4% of effective time), just ahead the UEFA Champions League (60.2%). The Portuguese Primeira Liga finds itself in the opposite position (50.9%).

The highest effective playing time among the five major European leagues was recorded for the German Bundesliga (58.5%), while the lowest was measured for the Spanish Liga (55.8%). As for the Champions League, Europa League games are more fluid than the average observed at the level of the 35 competitions surveyed: 57.1% of effective time compared to 55.3%.

The highest percentage of minutes in which the ball was in play for clubs in national competitions was recorded for matches of the Swedish side GIF Sundsvall (63.7%). This is 18% more than for games of the Portuguese team Feirense. Club Brugge tops the Champions League table (66.2%), while Borussia Mönchengladbach (62.5%), Liverpool (62.2%), Milan AC (61.2%), Barcelona (60.3%) and Paris St-Germain (60.1%) present the greatest figures for the big-5 leagues.

Issue number 241 of the CIES Football Observatory Weekly Post ranks countries according to the number of domestic league minutes played by their representatives in the big-5. The French (=players who grew up in France) top the rankings (19.7% of total minutes) ahead of the Spaniards (15.2%) and the Germans (9.8%). Overall, players originating from 85 countries have taken part in big-5 league matches so far this season.

In each league surveyed, the highest percentage of minutes per origin was measured for nationals. Nevertheless, the gaps are quite marked: from 62.7% in the French League 1 to only 35.3% in the English Premier League. The figures in the remaining championships are 39.0% in the Italian Serie A, 48.5% in the German Bundesliga and 61.0% in the Spanish Liga.

The greatest values for players originating from abroad were recorded for the French in England (10.9%) and Germany (8.0%), the Brazilians in Italy (7.0%) and France (6.8%), as well as for the Argentineans in Spain (also 6.8%). The English Premier League hosts the representatives from the most countries (54). This figure is 50 in the Serie A, 46 in the Ligue 1, 45 in the Bundesliga and only 40 in the Liga.

A brand new Performance Atlas was launched today on the CIES Football Observatory’s website. Powered with data from the leading company InStat, this unique tool presents exclusive pitch statistics at team level for 35 national competitions across Europe: 30 top division and 5 second division ones. The indicators cover all of the three key areas of the game: defence, passing and attack.

At defensive level, Dinamo Zagreb conceded the least shots on target per domestic league game so far this season (1.6). No club surveyed conceded as few passes in the own third of the pitch as Shakhtar Donetsk (40.8). From an attacking standpoint, the highest figures for shots on target and passes in the opponent third per match were recorded for AFC Ajax (9.1) and Manchester City (206).

At passing level, Chelsea FC tops the table for the percentage of accurate passes (89.9%), while Shakhtar Donetsk ranks first with regard to ball possession (67.0%). The tool also presents the data for the least performing teams. To know more about both the CIES Football Observatory and InStat, please contact us.

Issue number 240 of the CIES Football Observatory Weekly Post presents the ten most fielded U21 players in the big-5 leagues and Portuguese top division. Until last Friday, eleven U21 footballers had played the totality of domestic league minutes. Among them notably are hot prospects such as Rúben Neves, Jules Koundé, Arne Maier, Nikola Milenkovi? and Rúben Dias.

Up to six goalkeepers are to be found in the top 10 rankings: Emil Audero (Sampdoria), Gianluigi Donnarumma (Milan), Paul Bernardoni (Nîmes Olympique), Florian Müller (Mainz), Alban Lafont (Fiorentina) and Unai Simón (Athletic Club). With four representatives, FSV Mainz is the most represented club overall: Aarón Martín, Jean-Philippe Mateta, Florian Müller and Ridle Baku.

Overall, footballers born on or after 1st of January 1997 have played 15.4% of total domestic league minutes in the French Ligue 1, 14.7% in the German Bundesliga, 9.8% in the Italian Serie A, 6.1% in the Spanish Liga, 5.3% in the English Premier League and a mere 5.0% in the Portuguese Primeira Liga. The average age on the pitch per league and club is available in the CIES Football Observatory Demographic Atlas.

The long-term work carried out within the CIES Football Observatory focuses, in particular, on the demographic analysis of the football players’ labour market. The surveys carried out over the past decade allow us to reveal very clear trends. As illustrated in Monthly Report number 39, the footballers’ labour market in Europe is becoming deterritorialised by a decreasing presence of club-trained players, a stronger presence of expatriate footballers and greater mobility.

The percentage of club-trained players in the 31 European divisions surveyed reached a new record low on the 1st of October 2018: 16.9% (-6.3% in ten years). The decrease observed during the last year has been the greatest ever recorded (-1.6%). In parallel, the proportion of expatriates has increased to a record level of 41.5% (+6.8% in ten years). The process of internationalisation of squads has accelerated: from an annual growth of 0.55% between 2009 and 2013 to an average increase of 1.17% between 2014 and 2018.

In the conclusion, the authors state that “more and more teams are geared towards the short-term. In an increasingly segmented and speculative context, club officials tend to optimise financial returns on the transfer market to the detriment of more eminently sporting considerations. The increasing instability that results limits the sporting competitiveness of an ever greater number of teams, to the advantage of the wealthiest and better structured clubs, who increasingly dominate the proceedings”.

Every month, the CIES Football Observatory updates the transfer valuations of big-5 league players using its exclusive algorithm. Issue number 239 of the Weekly Post presents the top 10 list for each position. The highest figure overall was recorded for Kylian Mbappé (€216.5m). Ederson, Umtiti, Alexander-Arnold and Alli top their position’s rankings.

The transfer value of Kylian Mbappé increased by €23m compared to October. This allowed the French prodigy to outrank Harry Kane (€197.3m). The Englishman is now second ahead of Neymar, Mohammed Salah and Philippe Coutinho. Ageing Lionel Messi and Cristiano Ronaldo are now valued at €170.6m and €123.6m respectively.

This research note explains the CIES Football Observatory approach to predict from a scientific perspective the transfer value of professional players. Football stakeholders have increasingly recourse to our unique expertise for different purposes from decision-making to litigation. Do not hesitate to contact us for more information.

Issue number 238 of the CIES Football Observatory Weekly Post highlights clubs having trained the most players currently present in 31 European top divisions and the big-5 leagues respectively. The highest figures were recorded for AFC Ajax for players in the 31 top divisions (77) and Real Madrid for footballers in the big-5 (36).

Compared to 2017, Dynamo Kiev went up from 7th to 2nd place at European level (+ 15 players), reaching Partizan Belgrade (+10). The number of players trained by AFC Ajax also increased (+ 7). At big-5 league level, the top three remained the same. However, Olympique Lyonnais went up from 3rd to 2nd position (35 players, + 4), approaching Real Madrid (36, -4) and outranking Barcelona (34, =).

Following UEFA definition, training clubs are teams where footballers played for at least three seasons between 15 and 21 years. The percentage of minutes played by club-trained footballers in all of the teams from the 31 competitions studied is available in the exclusive CIES Football Observatory Demographic Atlas. More exclusive data is published through Twitter, Facebook and Instagram.

The CIES Football Observatory has developed an exclusive approach to assess the performance of players using the statistics produced by the leading data company OptaPro. Issue number 237 of the Weekly Post presents big-5 league footballers with the highest scores for the last 1,000 domestic league minutes played.

Aymeric Laporte heads the table in the area of rigour (duels), while Étienne Capoue ranks first for recovery (interceptions). Jorginho has the highest score in distribution and Cristiano Ronaldo in shooting. Neymar is at the top in two different tables: take on (dribbles) and chance creation (assists). According to the CIES Football Observatory approach, the Brazilian star is also the big-5 league MVP for the period considered.

At the head of the tables for footballers who played for less than 450 domestic league minutes during current season are Nicolás Otamendi (rigour), Milan Badelj (recovery), Marco Verratti (distribution), Douglas Costa (take on), Kevin de Bruyne (chance creation and MVP), as well as Konstantinos Mitroglou (shooting). More data is available in the exclusive player profile comparator.

Only three clubs in Europe have fielded this season players who have been in the first team squad since more than five years on average: Real Madrid (5.84 years), Barcelona (5.36) and Bayern Munich (5.26). Issue number 236 of the CIES Football Observatory Weekly Post also reveals that another Champions League participant, Viktoria Plze?, is the most stable club outside of the big-5 (4.28 years).

The majority of teams with the highest stability figures are among the most competitive teams in their respective leagues. The opposite holds true for the least stable clubs. The lowest stability levels were recorded for the Croatian team Istra (0.15 years) among the 31 top divisions surveyed and for the Italian side Parma (0.65 years) at big-5 league level.

The data for all teams in the competitions analysed is available in the exclusive CIES Football Observatory Demographic Atlas. Monthly Reports number 34 and number 38 discuss from multiple angles the link between stability and success. More analysis is also presented on a daily basis from our Twitter account. Follow us!

The CIES Football Observatory just published its 38th Monthly Report. The study analyses club strategies in the area of player turnover for the five major European leagues since 2005/06. It reveals that too many changes in line-ups do not constitute a good strategy for optimising results. On the contrary, high turnover levels tend to affect players’ confidence and aggravate the situation.

Seventeen of the twenty teams whose 11 most fielded footballers played for the least percentage of minutes relegated. This is a clear reflection of the real danger faced by clubs of finding themselves trapped in a vicious circle of poor results and instability, and vice versa. The existence of a negative correlation between turnover and points per match confirms the relevance of sticking with a core group of footballers to optimise performance.

The only team in the period studied that fielded less than 20 players over a season was Borussia Mönchengladbach in 2014/15. This did not prevent them from finishing in an excellent third place. That season, the team coached by Lucien Favre also participated in the Europa League, where it reached the last 16. While the achievement of good results reduces the incentives for player turnover, the Report shows that low player turnover in turn favours good results.

Issue number 235 of the CIES Football Observatory Weekly Post highlights teams having fielded the youngest and oldest line-ups in domestic league games so far this season (or since 1st of July for summer leagues). The extreme values at big-5 league level were recorded for two Italian teams: Fiorentina (23.79 years) and Chievo (29.53 years).

Danish side Nordsjaelland fielded the youngest line-ups for the 31 European top division leagues surveyed: 21.36 years on average. Two clubs from the youngest competition analysed, Croatia, rank second and third: NK Rudeš and NK Istra 1961. Four Turkish and three Cypriot teams are among the ten clubs having fielded the oldest line-ups. The highest figure overall was recorded for Europa League participants Apollon Limassol (30.93 years).

The data for all teams from the 31 top divisions studied are available for free in the exclusive CIES Football Observatory Demographic Atlas. This unique tool also presents the on-the-pitch figures for club-trained, expatriates, stability, turnover and height. Enjoy!

Issue number 234 of the CIES Football Observatory Weekly Post ranks clubs across Europe according to the number of minutes per shot attempted. The following teams head the table in the five major European leagues: Manchester City, Juventus, Olympique Lyonnais, Barcelona and Bayern Munich. Slavia Praha tops the rankings outside of the big-5.

So far this season, Manchester City players only needed 4’02” to take a shot. At the opposite end of the table, Huddersfield Town is the Premier League team needing the most minutes to shot: 12’08”. The highest figure overall in the 35 competitions surveyed was recorded for Hamilton Academical (Scotland): 18’12”.

The biggest gap within the same league was observed in Greece: from 5’00” for Olympiacos up to 18’07” for Panetolikos. Data used comes from OptaPro for the big-5 leagues and the English Championship and InStat for the remaining competitions. More information is published from our Twitter account or available on demand at football.observatory@cies.ch.

Manchester City has spent almost €1 billion in transfer indemnities to sign its present squad members (add-ons included). This is the highest figure ever measured for a football team. Issue number 233 of the CIES Football Observatory Weekly Post presents the data for all of the big-5 league teams.

Seven English Premier League teams are in the 11 top positions of the table. The biggest increase compared to last year was measured for Liverpool (from €437M to €704M). The Spanish giants (Barcelona and Real Madrid), Juventus and Paris St-Germain (2nd overall) are the only non-English teams in the top 11. The best-ranked German Bundesliga club, Bayern Munich, is 12th.

Total transfer expenditure to make up the squad for clubs from the five major European leagues went constantly up during the last decade. In 2010, a big-5 league had spent on average €67M to sign its squad members. In 2018, this figure reached a new record high of €161M. During the same period, the amounts invested to assemble the squad by English Premier League clubs went up from €126M to €326M.

The first CIES Football Observatory Weekly Post of the 2018/19 season assesses from an economic perspective paid transfers having taken place during last summer. It highlights that Thibault Courtois went to Real Madrid for a much lower amount than the estimated fair price (-€23 M). Conversely, Chelsea FC paid over the odds to recruit his substitute: Kepa Arrizabalaga (+€45 M).

The fair price corresponds to the average between the estimated cost for the most likely buyer before the transfer and the current transfer value. Both figures were calculated using the exclusive CIES Football Observatory algorithm. The correlation between fees estimated and reported for players transferred for money from big-5 league teams during last transfer window was 75%.

Rodri Hernández, Bryan Cristante, Fabinho Tavares and Clément Lenglet are alongside Thibaut Courtois in the top five for the best operations from an engaging club perspective. For Rodri and Lenglet, the existence of a release clause helped recruiting teams to sign them at a favourable price. As for Kepa Arrizabalaga, the CIES Football Observatory analysis reveals that releasing teams negotiated very well the transfers of Riyad Mahrez, Thilo Kehrer, Yerry Mina and Alex Meret.
