Issue number 379 of the Weekly Post presents the top 10 estimated transfer values as per the CIES Football Observatory algorithm for 10 non-big-5 league top divisions worldwide: Portugal, the Netherlands, Brazil, Belgium, the United States/Canada, Austria, Turkey, Denmark, Switzerland and Scotland. The greatest value overall was recorded for SL Benfica’s striker Darwin Núñez (€71 million).

Darwin Núñez meets all the most important criteria for a very high valuation: young age (not yet 23 years old), long contract (more than three years remaining), playing for a competitive team (SL Benfica) and performing very well, notably from a goal-scoring perspective. Rumours of the Uruguayan striker’s departure for an English top club are entirely plausible. As the latter tend to push up inflation in player prices, a €80-million deal, as publicly reported, is perfectly imaginable.

The following players have the top estimated values in the nine remaining leagues surveyed: Antony dos Santos (NED, €57M), Charles De Ketelaere (BEL, €40M), Gabriel Barbosa (BRA, €39M), Karim Adeyemi (AUT, €31M), Muhammed Aktürkoglu (TUR, €20M), Alan Velasco (USA, €20M), Liel Abada (SCO, €19M), Anders Dreyer (DEN, €15M), as well as Dan Ndoye (SUI, €15M).

Only players for whom we were able to recover the information on contract duration were included in the analysis. Nevertheless, as contract information for the most prominent footballers is generally available, the rankings should accurately reflect reality.

No team during current big-5 league season fielded club-trained players for a greater percentage of minutes than Athletic Club: 55.8%. The Basque side outranks local rivals Real Sociedad (43.9%), while Celta Vigo (41.2%) complete an all-Spanish podium. The Slovaks of MŠK Žilina (85.5%) top the table for clubs from 40 leagues worldwide. The data for all clubs is available in the 378th CIES Football Observatory Weekly Post.

The Colombians of Envigado (76.4%) head the rankings for the nine non-European leagues included in the study, ahead of four Argentinean teams (CA Banfield, CA Lanús, Rosario Central and CA Unión) and the Brazilians of Corinthians (56.3%). Club-trained footballers are defined as players who have been at their employer clubs for at least three years between the seasons during which they celebrated their 15th and 21st birthday.

At league level, the figures stretch from a record-low of 4.0% in the Greek Super League to a record-high of 26.0% in the Argentinean Liga Professional. On average, teams from the 40 leagues surveyed fielded club-trained players for 15.0% of domestic league minutes. Among the 42 teams who did not use club-trained footballers notably are Brentford, Bayer Leverkusen, Bologna and Udinese.

Issue number 377 of the CIES Football Observatory Weekly Post relies on technical data produced by InStat to unveil the best performing outfield players in 32 European leagues. Footballers were classified into fifteen technical profiles and ranked according to their performance level with respect to both teammates and opponents, their playing time, as well as their team and league sporting strength.

The following players top the table for the seven attacking profiles: Trent Alexander-Arnold (playmaker creator), Andrew Robertson (playmaker infiltrator), Bukayo Saka (infiltrator creator), Karim Benzema (shooter creator), Vinícius Júnior (shooter infiltrator), Thomas Müller (allarounder target man) and Robert Lewandowski (target man shooter).

At the top of the eight defensive profiles are Éder Militão (ground-to-air blocker), Virgil van Dijk (air blocker filter man), Aymeric Laporte (air blocker playmaker), David Alaba (ground blocker filter man), João Cancelo (ground blocker playmaker), Rodri Hernández (filter man playmaker), Bernardo Silva (defensive infiltrator) and Toni Kroos (defensive shooter).

Pioneers in the transfer economic valuation field, since 2010, the CIES Football Observatory has been developing a statistical method to assess market prices for professional football players. Issue number 376 of the Weekly Post presents the highest estimated transfer values for the 50 footballers who did not yet celebrate their 23rd birthday and made their big-5 league debut during current season.

Joško Gvardiol tops the table with an estimated value of €96.2M. While only 20-years-old, the centre back has established himself as a pillar of both RB Leipzig and Croatia. If transferred, he could break the record for the greatest fee ever paid for a defender. Gvardiol’s teammate at RB Leipzig Dominik Szoboszlai and FC Barcelona’s prodigy Pablo Gavi complete the podium for the most expensive U23 big-5 league rookies.

To know more about the method and variables used by the CIES Football Observatory research team to assess football players’ transfer fees and values, please refer to this scientific paper freshly published in the peer-review open access journal Economies. The fee estimate intervals for all big-5 league players are available for free on our website. Please contact us for more information about our approach and services.

Issue number 375 of the CIES Football Observatory Weekly Post presents the 100 best performing U21 outfield players from 32 European leagues according to a brand-new approach taking into consideration players’ performance compared to teammates, the employer team’s sporting level, as well as that of opponents. Bukayo Saka (Arsenal) outranks Mason Greenwood (Manchester United) and Patrick Wimmer (Arminia Bielefeld).

For all players listed, the study does not only mention their pitch position, but also the role played within the team according to fifteen technical profile categories. The latter are built from eleven game indicators collected by our partners InStat, covering eight different game areas as detailed in the 74th edition of the CIES Football Observatory Monthly Report: air defence, ground defence, recovery, distribution, take on, chance creation, air attack and shooting.

Bukayo Saka, for example, is part of the “infiltrator creator” category, defining players particularly active in the “take on” and “chance creation” areas. Mason Greenwood has a “shooter infiltrator” profile (“shooting and take on”), while Patrick Wimmer a “shooter creator” one (“shooting and chance creation). Players from 26 leagues and 14 technical profiles are in the top 100, with the French Ligue 1 (14 players) and the “infiltrator creators” (24 players) being the most represented.

Issue number 374 of the CIES Football Observatory Weekly Post ranks 60 leagues worldwide according to the percentage of minutes played since the 1st of January 2021 by footballers that did not yet celebrate their 21st birthday at matches played. The greatest figures were recorded in the Venezuelan (18.8%) and Danish top divisions (16.5%). The Saudi Pro League is at the opposite end (1.6%).

Regarding the average age of line-ups fielded, the lowest values were recorded in the Croatian top division (25.3 years of age), the Mexican Liga Expansión and the Danish Superliga. At the other end of the spectrum are three non-European leagues: the Paraguayan top division (28.9 years of age), the Thai League 1 and the Primera División in Bolivia.
