The 471st CIES Football Observatory Weekly Post presents the top 100 of players worldwide who did not yet turn 20 in terms of their relative experience level*. Lamine Yamal tops the list with 2.75 times more experience than the average measured for players of the same age and position. The Spaniard outranks his Barcelona teammate Pau Cubarsí (x2.42) and Real Madrid’s Endrick Felipe (x2.41).

Paris St-Germain’s Warren Zaïre-Emery is fourth, ahead of Manchester United's Kobbie Mainoo. The three youngest players in the top 100 are KRC Genk's Belgian Konstantinos Karetsas (16.8 years; 71st), LOSC Lille's Frenchman Ayyoub Bouaddi (16.9 years; 54th) and River Plate's Argentinian Franco Mastantuono (17.1 years; 22nd).

Outside the European big-5, the top three are Ecuador's Kendry Páez (Independiente del Valle, on loan from Chelsea), Brazil's Estêvão Willian (Palmeiras, also on loan from Chelsea) and Turkey's Yasin Özcan (Kasimpaşa). In total, 38 leagues are represented in the top 100, with a maximum of 13 players for the English Premier League, followed by 10 for the French Ligue 1.

* The level of experience is calculated on the basis of last year’s official game minutes, weighted by the sporting level of matches played.
