The 498th CIES Football Observatory Weekly Post ranks more than 900 clubs in 55 leagues worldwide according to a territorial anchorage index calculated from the proportion of national players and club-trained nationals among those fielded in the domestic league over the last year*. The Colombians of Envigado lead the way with 93.8% nationals and 54.2% club-trained nationals.

The Basques of Athletic Club and the Ukrainians of Dynamo Kyiv complete the podium, while the third highest-ranked European team, CA Osasuna, is only seventeenth. Latin American teams are over-represented among the most locally anchored ones. Paraguay’s Club Libertad are fourth, ahead of Mexico’s Chivas Guadalajara and Colombia’s Millonarios Bogota.

Another Colombian club (Atlético Nacional), two Argentinians (CA Belgrano and Vélez Sarsfield) and one Venezuelan (Caracas FC) also are in the top ten. For Asian clubs, the podium is made up of Sanfrecce Hiroshima (23rd), Uzbekistan’s FC Nasaf (24th) and another Japanese team : Kashiwa Reysol (28th). Adelaide United tops the table for Australia and Seattle Sounders for the MLS.

* Nationals are players who have grown up in the association of their home club, while club-trained nationals are those who have played for at least three seasons between the ages of 15 and 21 in their club of employment. The index is calculated on the basis of the gap from the general average for these two variables. Data refer to the last year or, for a few newly-promoted clubs, to the current season.

In this Weekly Post, the CIES Football Observatory analyses the differences observed over the last year between 63 leagues worldwide in terms of referees’ propensity to hand out penalty cards for fouls. Referees in Japan’s top two divisions are the least likely to issue cards for fouls (around one penalty card every ten fouls), while the opposite is true in Chile and Colombia (around one card every five fouls).

These gaps reflect both different degrees of severity in refereeing styles and discrepancies in the tendency of players to commit gross fouls. The Latin American leagues stand out for their harsh refereeing styles and the propensity of footballers to play violently, with the two phenomena feeding off each other, in contrast to Asia, where referees are less severe and players more disciplined.

The Post also presents the proportion of cards issued for fouls, with a maximum of 93.2% in the Ukrainian Premier League and a minimum of 59.2% in the Bolivian Primera División, where disputes and other forms of indiscipline are commonplace. The latter situation was also observed in the Brazilian Serie A (only 60.7% of penalty cards handed out for fouls), as well as in the top two tiers of Turkish football.

The 496th CIES Football Observatory Weekly Post ranks the teams of 37 leagues around the world according to the percentage of ‘minutes secured’, i.e. the share of the current season’s domestic league minutes played by footballers still under contract with a duration beyond the year 2026. Chelsea tops the list with 91.8% of minutes secured.

Monaco (91.3% of minutes secured) and AZ Alkmaar (89.2%) complete the podium of teams whose squad planning is most likely to bring stability in the coming years or, in the event of transfers, to generate substantial capital gains. Spain’s Real Sociedad (88.4%) and France’s Paris St-Germain also are in the top five positions.

The latter team has the highest value among UEFA’s Champions League quarter-finalists, ahead of another club well prepared for the future: Arsenal (85.8%). AZ Alkmaar aside, two other teams outside the five major European leagues feature in the top ten: Russia’s Zenit St. Petersburg and England Championship’s Coventry City.

The 495th CIES Football Observatory Weekly Post presents the world’s 100 best performing players from an attacking perspective in terms of their statistics in three areas of the game : take on, chance creation and finishing. Michael Olise tops the rankings with an average index of 88.5 in these three domains and a maximum value of 99 in chance creation.

The Bayern Munich’s French international is ahead of Barcelona’s Spaniard Lamine Yamal (87.7) and Bayer Leverkusen’s German Florian Wirtz (85.0). The top 10 also includes two Brazilians (Vinícius and Savinho), two Frenchmen (Ousmane Dembélé and Désiré Doué), an Englishman (Bukayo Saka), an Egyptian (Mohamed Salah) and a Dutchman (Noa Lang).

The latter is the top-ranked player active outside the big-5 European leagues. He is ahead of Estêvão Willian (Palmeiras, on loan from Chelsea) and Rodri Sánchez (Al-Arabi). The oldest players in the top 100 are Iago Aspas (Celta Vigo), Karim Benzema (Al-Ittihad) and Yacine Brahimi (Al-Gharafa). Only footballers who played at least 1,080 minutes during the current season were taken into account.

Issue number 494 of the CIES Football Observatory Weekly Post presents the 100 players from outside the big-5 European leagues whose transfer value has risen the most over the last six months. At the top of the list is Porto’s Spanish striker Samu Aghehowa, second top scorer in the Portuguese top flight, with an increase of €39 million (from €29.6m to €68.6m).

Palmeiras’ new Brazilian full international Estêvão Willian, owned by Chelsea, comes second with an increase of €30 million (from €30m to €60m). Benfica’s Spaniard Álvaro Carreras completes the podium (+€28m) ahead of teammate Tomás Araújo (+€25m). Three other players active in Portugal are in the top 10 (Conrad Harder, Geovany Quenda and Roger Fernandes), along with Antoni Milambo (Feyenoord), Jan-Carlo Simić (Anderlecht) and Mika Godts (Ajax).

All estimates have been calculated on the basis of a statistical model developed exclusively by the CIES Football Observatory research team, built on almost 10,000 paid transactions, as detailed in this scientific paper. This tool presents the best-valued players per team in 65 leagues worldwide. A paying platform with weekly valuations of over 30,000 players is also available for professionals in the game.

To celebrate its twenty years of existence and pay tribute to the clubs developing the talent that makes us love football, the CIES Football Observatory is very proud to present a study of the teams that have trained* the most players fielded in Europe’s big-5 over the last two decades. The top three are Real Madrid (166 players), Barcelona (156) and Paris St-Germain (111).

Olympique Lyonnais and Manchester United (both with 103 players) are at the foot of the podium, followed by Stade Rennais and Atalanta (94). Among the teams outside the big-5, the three having trained the most footballers who have played in the five major leagues since 2005/06 are Ajax (73 players), Sporting CP (64) and River Plate (51). Boca Juniors (49 players) and Benfica (45) are also in the top 5.

To celebrate twenty years of hard work, the CIES Football Observatory research team has also prepared a more in-depth study, published as the 99th Monthly Report, notably including details of the footballers trained by team and a map of all the big-5 clubs in which they have played. Enjoy the read and thank you for your interest!

* Training clubs are defined as the first teams where footballers have played for at least three years between the seasons of their fifteenth and twenty-first birthdays (seasons of these birthdays included).
