Top transfer values: U23 big-5 league rookies

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 the 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.
