These are the results of the new "Weekly Report" of CIES

The International Center for Sports Research from Switzerland has published a new report (now it is traditionally done on Wednesdays instead of Mondays).
Analysts have compiled a list of clubs from 60 Leagues of the world, which use the largest number of their club-trained footballers in the matches.
The generally recognized concept of "club-trained footballer" refers to a player who has spent at least three summers under the age of 21 in the structure of a certain FC.
CIES indicates that in this regard, Dynamo Kyiv is the No. 1 club in the world: this season in VBET League games, the capital team gave 82.9% of playing time to its club-trained footballers.
