The CIES Football Observatory is pleased to inform that the ratings module on its website presents the updated transfer values of all players in the five major European leagues. The most significant changes since June were recorded for full internationals, as well as for footballers transferred for big money to big clubs.

Among new full internationals, there are many German players such as Sandro Wagner, Kerem Demirbay, Lars Stindl, Marvin Plattenhardt, Diego Demme and Kevin Trapp. The transfer value of Jemerson (Monaco) went also up from €35m to €50m following his first cap with the Brazilian national A-team.

Signed for fees very close to CIES Football Observatory estimates, players such as Romelu Lukaku, Bernardo Silva, Alexandre Lacazette and Corentin Tolisso have now even greater values. The future trend will depend on their ability to establish themselves as key players in their new and more prestigious teams.

Interrupted as usually during the summer, the publication of our weekly posts and monthly reports will start again with the beginning of the 2017/18 season. In the meantime, we communicate on Twitter. Do not hesitate to follow us: @CIES_Football.

The CIES Football Observatory is happy to promote the European Hackathon on Football. The event is organised by the Italian Football Federation (FIGC), in collaboration with the University of Trento and the Autonomous Province of Trento. It will be held on the 14th and 15th October 2017 in Trento (northern part of Italy).

The hackathon is a meeting point where virtuous high-tech people, people passionate about innovation and entrepreneurship (as well as football) gather and aggregate in order to create and submit to the evaluation of a jury of experts applied solutions and/or projects in the field of the “theme” of the contest: match analysis and community of FIGC members.

Parallel to the hackathon, a series of public events, conferences and meetings on innovation, technologies, football and sports will be organised. They will involve players, managers, sponsors, partners, communication experts and journalists. The CIES Football Observatory’s head and founder, Dr. Raffaele Poli, will participate as a guest speaker.

Participation is free but previous registration is needed. More information is available here.

The CIES Football Observatory research team has developed a powerful approach to estimate on a scientific basis the transfer value of professional football players. Issue number 192 of the Weekly Post presents the list of the 110 big-5 league footballers with an estimated value of more than € 40 million. Barcelona’s Neymar tops the table ahead of Tottenham’s Dele Alli and Harry Kane.

The exclusive CIES Football Observatory algorithm is based on the thorough analysis of almost 2,000 paying fee transfers. The variables through which transfer values are modelled notably include the performance of both players and employer clubs, international status, contract, age and position. More information is available in the 16th edition of the CIES Football Observatory Monthly Report.

The English Premier League is over-represented among footballers listed. The estimated transfer value of the tenth most expensive Premier League player is € 85 M. This figure is € 73 M for the Spanish Liga, € 51 M for the Italian Serie A, € 47 M for the German Bundesliga and € 40 M for the French Ligue 1. The youngest player in the rankings is the French prodigy Kylian Mbappé (€ 93 M), while the oldest is the evergreen Portuguese striker Cristiano Ronaldo (€ 112 M).

The ratings module on the CIES Football Observatory website presents the estimated transfer value for all big-5 league players. Deeper analysis is undertaken on a consultancy basis. More information is also published through the official CIES Football Observatory Twitter account. For further enquiries, please contact us at football.observatory@cies.ch.

Women’s football is currently undergoing a welcome development. At the elite level, the process of professionalisation is well underway in several countries worldwide. Following in the footsteps of the CIES Football Observatory studies, Monthly Report number 26 analyses the composition of squads in five of the world’s most developed leagues: four European (Germany, Sweden, France and England), as well as the Women’s National Soccer League in the United States.

The report notably highlights that women’s football is generating more and more international movements. On the 1st June 2017, 274 footballers were expatriated in the 55 clubs analysed (5.1 per team). Only 5 clubs out of 55 did not field expatriate players. Conversely, expatriates played a majority of minutes in five teams: SC Sand, Bayern Munich and Wolfsburg in Germany, as well as Rosengård and Vittsjö in Sweden.

The study also underlines that the most successful women’s teams field almost exclusively players with international status. The highest values in absolute were measured at Champions League winners Olympique Lyonnais (97.7%) and Wolfsburg (97.4%). Full internationals also played more than 80% of match minutes at Rosengård, Bayern Munich, Paris St-Germain and Eskilstuna United.

While the general level of women’s football grows, the increase in the means at the disposal of the wealthiest clubs poses a problem in terms of competitive balance. The eventual creation of international leagues bringing together the richest teams is an option. However, this should not occur at the expense of the multiple actors having historically worked, and often struggled, so that the women’s game could progress and reach its current level.

Weekly Post number 191 of the CIES Football Observatory presents turnover strategies followed in domestic league matches of the 2016/17 season by clubs from 27 top division European leagues. Chelsea FC holds the record for the highest percentage of minutes played by the 11 most employed footballers: 85.5%. Conversely, Manchester United is among the 50 clubs with the highest turnover rate.

Many Champions League participants are part of the 50 clubs in which the 11 most fielded footballers played for the highest percentage of minutes: Tottenham, Napoli, Sporting Clube de Portugal, Monaco and Atlético Madrid. Europa League finalist Ajax also features in the list. This finding shows that it is possible to be successful both at domestic and European level without high turnover rates.

However, Manchester United followed a radically different strategy. José Mourinho’s team is among the 50 teams in the 27 leagues surveyed with the lowest percentage of minutes played by the 11 most fielded footballers: 62.8%. This reflects an unusually high level of changes in line-ups selected. In the future, more stability is probably needed to sustainably improve results.

Issue number 190 of the CIES Football Observatory Weekly Post ranks footballers from the five major European leagues according to the number of minutes played in official games since July 1st 2016. The French and Atlético Madrid star Antoine Griezmann tops the table ahead of Wilfred Ndidi (Genk, Leicester and Nigeria) and teammate Koke.

Apart from Griezmann, Ndidi and Koke, five other footballers played for more than 5,000 minutes: Danijel Subaši? (Monaco and Croatia), Kamil Glik (Monaco and Poland), Neymar (Barcelona and Brazil), Paul Pogba (Manchester United and France), as well as Marquinhos (Paris St-Germain and Brazil).

In the top 100 positions of the rankings are ten players of the two Champions League finalist teams: five from Juventus (Higuaín, Buffon, Bonucci, Mandžuki? and Khedira) and five from Real Madrid (Kroos, Ronaldo, Ramos, Marcelo and Navas). While some fatigue certainly exists, it should not prevent players from producing an enjoyable show on Saturday.

Issue number 189 of the CIES Football Observatory Weekly Post ranks big-5 league players according to their tackling skills. The tackling index is calculated by multiplying the average number of tackles attempted per 90 minutes and their success rate. Only players fielded for at least 1,500 domestic league minutes are included in the analysis.

Players from three different championships figure in the top three positions of the rankings: Valentin Rongier (Nantes), Carlos Casemiro (Real Madrid) and Idrissa Gueye (Everton). The top ranked Bundesliga player is Douglas Santos (Hamburg), while Gastón Brugman (Pescara) tops the Italian Serie A table.

In quantitative terms, the big-5 league who player who attempted the most tackles is Sergio Álvarez (Sporting Gijón): 138. Idrissa Gueye (Everton) achieved the most: 99. The highest success rate among players in the top 100 list was recorded for Pedro Obiang (West Ham): 89%. A successful tackle is defined by our data provider OptaPro as tackles resulting in winning possession or the ball being put out of play.

Issue number 188 of the Weekly Post presents the best players of the 2016/17 big-5 league season. The rankings were elaborated according to the exclusive CIES Football Observatory’s approach to measure player performance on an objective and comparable basis. Lionel Messi outranks Cristiano Ronaldo in the table for wingers.

Three Bayern Munich players top the rankings in their respective position: Manuel Neuer for goalkeepers, Javi Martínez for centre backs (ahead of teammate Mats Hummels), as well as Thiago Alcântara for central defensive midfielders. Only footballers who have played at least 2,000 minutes in domestic league games are included in the analysis.

Alex Sandro and Marcelo (full backs), Kevin de Bruyne (central attacking midfielders), Lionel Messi (wingers) and Dries Mertens (centre forwards) head the rankings for the other positions considered. Except for de Bruyne and Marcelo, all these players are also to be found in the CIES Football Observatory’s 4-3-3 best XI of the season alongside Bruno Peres (right full back), Paul Pogba and Naby Keita (box-to-box midfielders), as well as Cristiano Ronaldo (left winger).

The 25th edition of the CIES Football Observatory Monthly Report analyses the presence of expatriate footballers in 137 leagues from 93 national associations at worldwide level. In total, 12,051 expatriates originating from 174 national associations are currently present in the 2,120 clubs studied. Brazilians are the most numerous abroad (1,202 players), ahead of French (781) and Argentineans (753).

The report also presents the main destinations for the principal exporting countries. While the main destination of Brazilians is Portugal (221 players), that of French is England (107 players). The most numerous contingent of Argentineans is to be found in Chile (106 players). Also well represented in foreign associations, English footballers mainly go to Wales (143 players) and Scotland (114).

Expatriate players are present in all of the 93 countries and 137 leagues surveyed. Their overall percentage in squads is 21.6%. The CIES Football Observatory Digital Atlas provides data on their playing time in 31 top division leagues of UEFA member associations.

The ability to both create and convert big chances is a key success factor. However, issue number 187 of the CIES Football Observatory Weekly Post highlights that in four out of the five major European leagues, teams heading the table distinguished themselves from runner-up clubs above all for their ability to score with no clear-cut opportunity available.

Rome (26), Paris St-Germain (25), Tottenham (34) and RB Leipzig (25) scored significantly fewer goals from situations with no big chance available than Juventus (37), Monaco (36), Chelsea (41) and Bayern Munich (40). In no big-5 European league, the club having created the most clear-cut scoring opportunities tops the rankings: PSG, Barcelona, Rome, Borussia Dortmund and Manchester City.

The key question is thus to know why some teams scored more goals with no big chance available. Luck certainly plays a role at this level. However, the greater desire to win should probably also be taken into account. In addition, while the best form of defence is attack, we should not forget the importance of defensive teamwork to win trophies.

Issue number 186 of the CIES Football Observatory Weekly Post analyses the results of big-5 league teams according to their transfer expenditure to sign the players fielded over the 2016/17 season. A positive and significant correlation was measured between fees paid and points per match in all leagues surveyed. This confirms the strong link between money and success.

Three teams performed much better than the amounts invested on the transfer market would have suggested: West Bromwich Albion, Atalanta and Freiburg. The most positive gaps in the French Ligue 1 were recorded for Nantes and Nice. Eibar and Alavés are at the top of the table at Spanish Liga level.

The club having so far the most under-performed with regard to its expenditure in signing players fielded is Wolfsburg. Results obtained by Valencia, Bayer Leverkusen, Hamburg and Sunderland were also clearly disappointing. The same holds true for Bastia in France, as well as for Inter and Palermo in Italy.

Issue number 185 of the CIES Football Observatory Weekly Post presents the top 100 list of the best performing big-5 league players in the area of dribbling. Middlesbrough’s Adama Traoré outranks Eden Hazard (Chelsea) and Allan Saint-Maximin (Bastia). Neymar, Lionel Messi and Alexis Sánchez also are in the top 10 positions of the rankings.

The dribbling index is calculated by dividing the number of dribbles attempted by the percentage of successful ones. This allows us taking into account dribbling skills from both a quantitative and a qualitative perspective. In quantitative terms, the big-5 league player who attempted the most dribbles so far is Barcelona’s Neymar (269), ahead of Wilfried Zaha (Crystal Palace) and Felipe Anderson (Lazio).

The best ratio of successful dribbles among players in the top 100 list was recorded for OGC Nice’s midfielder Wylan Cyprien (87%). At second position is another French Ligue 1 player: Marco Verratti (Paris St-Germain). The best ratio for players who attempted more than 100 dribbles was observed for Eden Hazard: 75%.

Dear subscriber,

The CIES Football Observatory research team is happy to inform you that the Digital Atlas was updated. It now takes into account domestic league games played during the last six months. This exclusive tool allows you to compare the squad make-up of teams in 31 top division leagues of UEFA member associations.

In addition, the new top 100 lists of the teams having fielded club-trained players for the highest percentage of minutes, the most stable line-ups, as well as the youngest ones are now available. The rankings refer both to the 31 top division leagues of UEFA member associations and the five major European championships (Spanish Liga, English Premier League, German Bundesliga, Italian Serie A and French Ligue 1).

We hope that you will enjoy these tools. Any feedback is welcome. We also kindly invite you to follow us on Twitter. Thank you for your interest!

The CIES Football Observatory published today the 24th edition of its Monthly Report. The study focuses on the demographic evolution of the big-5 European leagues since the start of the 2009/10 season. It notably shows that the percentage of minutes played by club-trained footballers in the English Premier League reached a new record low during the current season (6.1%).

The Report also highlights the increase in the playing time of expatriate footballers at the level of the five major European championships. Between 2009 and 2017, the percentage of minutes played by expatriates went up from 44.4% to 48.2%. A new record high was measured in January 2017: 48.7%. If this trend continues, the symbolic 50% threshold will be reached soon.

Today, expatriates already play the majority of minutes in the English Premier League and the Italian Serie A. In the two cases, we are close to record values. The Serie A also differentiates itself from the other leagues with regard to the extent of the increase measured since the 2009/10 season. On the other hand, the German Bundesliga is the only championship where the current value is lower than that recorded at the beginning of the period investigated.

The employment level of young players also varies considerably according to league. During the period studied, the French Ligue 1 overtook the German Bundesliga to become the competition where teams have the most confidence in U21 players. At the other extreme, the English Premier League overtook the Italian Serie A as the league in which U21 footballers have the least amount of playing time.

During the last six months, the percentage of domestic league minutes played by U21 footballers was 5.2% for the Premier League, 10.1% for the Serie A, 11.1% for the Liga, 13.3% for the Bundesliga and 15.7% for the Ligue 1. In England, the current value is very close to the record low measured in August 2013. In Italy, however, the record high measured in January 2017 could be beaten again by the end of the season.

The CIES Football Observatory Weekly Post n° 184 presents the percentage of matches ended with a three-goal gap or over for 31 top division European leagues, as well as UEFA’s Champions League and Europa League. The analysis shows that the Champions League is among the most unbalanced competitions.

From the group stage up until now, the goal gap for more than a fifth of Champions League matches was at least three (21.0%). This is the third highest figure among competitions surveyed after those recorded in the Cypriot (22.5%) and Austrian (21.5%) top divisions. However, the value measured in the Europa League is particularly low (13.5%).

The big-5 leagues are also in the first half of the most unbalanced competitions. This finding reflects the increasing wealth gaps between participating teams. To re-balance competitions, the only solution would be to improve the distribution of financial (TV rights) and human (transfer market) resources at both national and international level.

Issue number 183 of the CIES Football Observatory Weekly Post ranks 31 top division European leagues according to goals scored since July 1st 2016. At the top of the table is the Swiss Super League (3.33 goals per game). The Russian Premier League finds itself at the opposite end of the spectrum (1.99).

At the level of the five major European championships, the figures vary from 2.90 goals per match in the Spanish Liga to 2.60 in the French Ligue 1. The English Premier League (2.84) ranks sixth (out of 31) at European level and second between the big-5 leagues.

Generally speaking, a negative correlation exists between the number of goals scored and the number of cards issued by referees (see Weekly Post n° 182). More goals equals to fewer cards. This finding confirms the existence of cultural differences in the way of approaching the matches according to country.

For the first time, issue number 182 of the CIES Football Observatory Weekly Post presents data on cards issued by referees. The 31 top division European championships surveyed are ranked according to the average number of cards given per game. The Greek Super League heads the table (5.52), while the Norwegian Eliteserien is at the bottom of the rankings (2.93).

Southern and Eastern European countries are over-represented among those where the referees issue the most cards. On the contrary, in the majority of Northern and Western European countries, the number of cards is relatively low. These gaps reflect the existence of different cultures both from a player and a referee behaviour perspective.

Generally speaking, the number of yellow cards is correlated to that of red ones. The French Ligue 1 is an exception. At international level, French referees issue few yellow cards, but a lot of red ones. At the opposite end of the spectrum, in the English Premier League, the amount of red cards is very low compared to that of yellow cards.

Issue number 181 of the CIES Football Observatory Weekly Post highlights the 100 clubs from 31 top division championships of UEFA member associations having on average fielded the oldest line ups in the domestic league matches played during the last six months. The most represented countries in the rankings are England and Turkey (10 clubs each), followed by Cyprus and Russia (9 teams).

At the top of the table is the Italian side Chievo Verona (32.1 years). The average age on the pitch of five other clubs was higher than 30 years: three from Cyprus (AEK Larnaca, Nea Salamis and Apollon Limassol), one from England (West Bromwich) and one from Greece (Kerkyra). The values per league are freely available online via the CIES Football Observatory Digital Atlas. This tool also allows users to access the data for all clubs in the leagues surveyed.

In addition, the CIES Football Observatory website presents the top 100 list of the youngest top division teams from the 31 UEFA member associations taken into account. The most represented country is the Netherlands (12 clubs), followed by Croatia (8), Germany and Slovakia (7 teams each). No English Premier League team is in the top 100 positions. The youngest team overall is the Slovakian side Senica (22.2 years).

The studies carried out since 2005 by the CIES Football Observatory are not only geared towards the general public, but are also useful to actors in the game. The 23rd Monthly Report illustrates an approach that allows a professional football league to analyse on an objective basis its international positioning and influence in a positive way the strategic choices of the clubs that compose it.

The example chosen is that of the Swiss Football League. This choice is a result of the trust, built up over a number of years, that this institution has shown towards the CIES Football Observatory. This trust has led to the commissioning of several studies and research reports. These documents are available freely online in both French and German on the Swiss Football League website.

The Report notably highlights that in the current context of economic polarisation, the good health of the vast majority of clubs and leagues worldwide will depend on their ability join forces in their own interests. From the sporting point of view, the emphasis must be placed on improving the protection of the work of training, and, more generally, to increase the level of solidarity in the transfer system.

The first CIES Football Observatory Weekly Post was published in March 2012. To celebrate this birthday, we ranked the 54 clubs always present in the big-5 leagues during the last five years according to the number of players fielded in domestic league games. Italian side Genoa used the most players overall: 137! At the opposite end of the spectrum are Athletic Club Bilbao, Bayern Munich and Borussia Mönchengladbach (55 players).

Eight of the eleven teams always present in the big-5 who fielded more than 100 players in domestic league matches since March 2012 are Italian. This reflects the very speculative transfer market approach existing in Italy. The greatest figures in squad turnover per league were recorded at Genoa (137 players), Granada (129), Sunderland (103), Nice and Stade Rennais (91, including many players from the youth academy), as well as Werder Bremen (90).

Many well-structured and performing teams fielded the fewest players during the period analysed. Among them, we notably find Bayern Munich (55 players), Paris St-Germain (64), Real Madrid (64 too), Arsenal (65) and Barcelona (66). The Weekly Post also presents the footballer who played the most domestic league minutes during the last five years for each club taken into consideration. St-Etienne’s goalkeeper Stéphane Ruffier tops the table: 16,650 minutes.

Issue number 179 of the Weekly Post presents the best performing big-5 league players in the six areas of the game that make up the exclusive CIES Football Observatory approach for the technical analysis of performance. The data refers to the last 1,000 minutes played by each player in domestic league matches. Only footballers fielded for at least 360 minutes since January 1st are included.

Nicolás Otamendi (Manchester City) heads the table for rigour ahead of Marquinhos (Paris St-Germain) and Javi Martínez (Bayern Munich). In the area of recovery, Sead Kolašinac (Schalke 04) outranks teammate Benedikt Höwedes, Xabi Alonso (Bayern Munich) and Omar Mascarell (Eintracht Frankfurt). Three players top the distribution rankings: Thiago Motta (Paris St-Germain), Jorginho and Marek Hamšík (both Naples).

Two young talents have the highest possible score for take on: Allan Saint-Maximin (Bastia, on loan from Monaco) and Adama Traoré (Middlesbrough). Kevin de Bruyne (Manchester City) and Cristiano Ronaldo (Real Madrid) head the tables for chance creation and shooting.

Seven players are in the top 10 rankings in two different areas: Xabi Alonso, Ander Herrera and Arturo Vidal in recovery and distribution; Toni Kroos in distribution and chance creation; Alejandro Gómez and Neymar in take on and chance creation; as well as Lionel Messi in both chance creation and shooting.

The profile of all big-5 league players is available here.

Issue number 178 of the CIES Football Observatory Weekly Post presents big-5 league players who have been for the longest consecutive period in the first team squad of their current club. Only footballers who have participated in domestic league matches during the ongoing season are taken into account.

Francesco Totti heads the overall table. The Italian world champion has been in Roma’s first team squad for 24 consecutive years (since 1993)! At second position is Chelsea’s centre back John Terry (18.5 years), followed by Juventus goalkeeper Gianluigi Buffon and Caen’s defensive midfielder Nicolas Seube (both 15.5 years).

The average number of consecutive seasons in the employer club of the most loyal player per team varies between 8.6 years in the German Bundesliga and 7.7 years in the French Ligue 1. Olympique de Marseille is a very specific case as the lost loyal players fielded in domestic league games this season are present in the first team squad since 1.5 years only!

Issue number 177 of the CIES Football Observatory Weekly Post presents the list of footballers trained by clubs qualified for the Champions League last 16 round playing in these teams. The number of footballers trained varies between 11 for Barcelona to only one for Manchester City and Napoli.

Among the 11 players trained by Barcelona, six play for the Catalan side. The remaining ones play for five different clubs still competing in the Champions League: Benfica (Grimaldo), Dortmund (Bartra), Napoli (Reina), Bayern (Thiago Alcântara) and Paris St-Germain (Thiago Motta). The youngest Barcelona’s product, Rafinha, is already aged 24. This tends to confirm the decline of La Masia as underlined in issue number 163 of the CIES Football Observatory Weekly Post.

Four Champions League clubs have trained less than three players under contract with teams participating in the last 16 round: Leicester (King, Chilwell), Juventus (Marchisio, Kean), Manchester City (Schmeichel) and Napoli (Insigne). For these teams, the training and promotion of players from the youth academy is clearly not a priority.

Goalkeepers occupy a particular status in football teams. The qualities needed to play in this position are very different from those required from outfield footballers. Issue number 22 of the CIES Football Observatory Monthly Report compares goalkeeper characteristics with those of footballers playing in other positions.

The study confirms the specificity of the position of goalkeeper based upon criteria taken into account: height, age, origin and mobility. From the point of view of height, clubs are more and more reticent to promote goalkeepers under 190cm. This observation holds particularly in England and Germany, where the average height of goalkeepers is already over 190cm.

Regarding age, the analysis reveals the greater longevity of goalkeepers. The importance given to experience is particularly striking in England and Italy. In both cases, keepers are on average aged over 29 years. In all leagues surveyed, the regular goalkeepers are significantly older than the reserve ones.

From the standpoint of origin, the Report shows that the labour market for goalkeepers is much less international than that of outfield players. The difference is particularly noteworthy with respect to forwards. The study also indicates that the gap in the percentage of expatriates between goalies and outfielders tends to increase.

Finally, the analysis highlights the greater stability of goalkeepers. Their average length of stay in their employer club is much longer than for outfielders. In this case too, the biggest difference was observed in comparison to forwards. The latter are the most mobile in the football players’ labour market.
