Best players of the last semester: eight areas

Thanks to the collaboration with Impect, the CIES Football Observatory has developed performance indices on a 100 basis in eight areas of play. This Weekly Post presents the 50 outfield footballers with the highest values in each domain for the last six-month domestic league games, with each player appearing only in the ranking for the area in which they scored highest.

The following players head the tables in the different areas : Virgil van Dijk (air defence), Moisés Caicedo (ground defence), Rúben Dias (defensive build-up), Pedri González (orchestration), Michael Olise (take on), Lamine Yamal (chance creation), Kylian Mbappé (finishing) and Erling Haaland (air attack).

The youngest players in the top 50 of each category are as follows : Eivind Helland (air defence), Agustín Medina (ground defence), Pau Cubarsí (defensive build-up), Warren Zaïre-Emery (orchestration), Estêvão Willian (take on), Lamine Yamal (chance creation), Franco Mastantuono (finishing) and Thierno Barry (air attack).

Player asset evolution: Chelsea ahead of PSG

The 516th CIES Football Observatory Weekly Post highlights the clubs whose estimated transfer value of players owned has changed the most, positively or negatively, over the past year. We present both the change in absolute terms (‘gross’ evolution) and the change considering the financial balance of transfer operations (with sell-ons, not including add-ons) completed during the last two transfer windows (‘net’ evolution).

In terms of net evolution, Chelsea tops the list (+€364 million) with player valuations up €372m and a balanced net spending for the last two transfer windows : -€8m. The reigning world champions are ahead of the European ones, Paris St-Germain (+€303 million). German side Eintracht Francfort (+€294m) rounds up the podium. Manchester United (-€377 million) and Manchester City (-€315m) are at the opposite end of the table.

The Post also presents the estimated transfer value of all players owned by clubs (not including any sell-on related sums). In this case, the top three are Chelsea (€1.81 billion spread across 50 players), Real Madrid (€1.68 billion, 32 players) and Manchester City (€1.47 billion,46 players). Five other clubs have a total estimated value in excess of one billion : Arsenal, Paris St-Germain, Liverpool, Barcelona and Tottenham.

Youngest teams: global rankings

The 515th CIES Football Observatory Weekly Post ranks teams from 69 leagues around the world according to the average age of line-ups fielded in the current domestic league season. Not including B-teams, the lowest value overall was recorded for Latvian side FK Metta (20.96 years), while the highest was measured for Saudi Arabia’s Khaleej FC (31.62 years).

In the five major European leagues, the following teams fielded, so far, the youngest line-ups : Chelsea (Premier League, 24.36 years), Barcelona (La Liga, 25.22 years, ahead of Real Madrid, 25.67 years), RC Strasbourg (Ligue 1, 21.45 years, 2nd lowest value overall, ahead of Paris St-Germain, 24.09 years), Eintracht Frankfurt (Bundesliga, 24.48 years) and Parma Calcio (Serie A, 24.26 years).

The Post also presents the percentage of minutes per age category (≤21, 22-25, 26-29, ≥30). Italian champions Napoli are the Champions League big-5 participant with the highest percentage of minutes by players aged 30 or over (46.8%, up to 84.5% for over 26-year-old players), ahead of Bayern Munich (36.0%, and 70.3% respectively). These proportions are much lower for Champions League title holders Paris St-Germain : 3.0% and 23.4%.

CIES “Ballon d’Or”: Lamine Yamal !

With the real Ballon d’Or to be awarded today by France Football, the CIES Football Observatory has had fun ranking the 100 best players in the world over the past year using a purely statistical method. The latter takes into account the performances of outfield footballers during the last year in six game areas (see here, data from Impect), as well their employment, matches’ sporting level and results (see here).

FC Barcelona prodigy Lamine Yamal ranks first ahead of Kylian Mbappé and his teammate Pedri González. The best centre back is Virgil van Dijk (4th), while Achraf Hakimi has the highest score among full/wing backs (9th overall). One of the favourites to win the real Ballon d’Or, Ousmane Dembélé, ranks seventh in this case, also behind Michael Olise and Mohamed Salah.

The three oldest players in the top 100 are Luka Modrić, Lionel Messi, and Nicolás Otamendi, while the youngest are Lamine Yamal, Pau Cubarsí and Désiré Doué. Virgil van Dijk tops the rankings in terms of experience, while the top three in terms of pure performance are Kylian Mbappé, Lamine Yamal and Lionel Messi.

Costliest squads: Chelsea at the top

Issue number 513 of the CIES Football Observatory’s Weekly Post presents the 100 clubs worldwide having committed the most money in transfer fees (including add-ons regardless of actual payment) to recruit their current first team squad players. Chelsea tops the list with a total investment of €1,314 million, of which €134 million for the most expensive signing (Moisés Caicedo, 10%).

Manchester City (€1,128 million) and Manchester United (€1,071m) round up the podium, followed by two other English clubs : Liverpool (€1,065m) and Arsenal (€1,001m). No club outside England has invested more than one billion to assemble its squad, with a maximum of €873 million for Champions League title holders Paris St-Germain (7th, just ahead of Real Madrid). Al-Hilal tops the rankings for non-European clubs (€451m, 19th).

Compared to the same date last year, the amounts committed by the ten clubs having invested the most in transfer fees to build their current first team squads increased by 15% (from 8.44 to 9.67 billion) and those of the top 100 by 12% (from 26.23 to 29.42 billion). This evolution is directly linked to the record transfer spending registered in 2025, as illustrated in this video.

Most likely champions: 29 leagues

The 512th Weekly Post of the CIES Football Observatory presents the results of a statistical model forecasting the probability of winning the title for clubs in 29 leagues. The model combines sporting variables (Impect data on passes in the opponent’s half), economic variables (transfer fees invested to recruit players fielded) and demographic variables (players’ last year minutes and their matches’ sporting level).

The highest likelihood in absolute terms was recorded for Serbia’s side Crvena Zvezda (76.2%), followed by France’s Paris St-Germain (73.0%) and South Africa’s Mamelodi Sundowns (70.6%). Conversely, among the 30 leagues analysed, the most open are the UAE Pro League (at most 23.5% chance of success for Shabab Al Ahli), the Italian Serie A (25.6% for Inter), and the Dutch Eredivisie (28.6% for Feyenoord).

In the Premier League, Liverpool has the highest probability of being crowned champions again (28.9%), ahead of Arsenal (18.8%) and Chelsea (16.2%). In La Liga, Real Madrid are the favourites (40.6% chance of winning the league), ahead of Barcelona (29.6%) and Atlético Madrid (22.1%). In Serie A, the top three are Inter (25.6%), Juventus (18.2%), and Napoli (17.4%). In Bundesliga, Bayern Munich stands out with 61.4%, ahead of Borussia Dortmund (8.8%).
