A report from CIES Football Observatory has put together a 270-strong list of players who are 20 and under and looked at how much playing time they've had in 2023. A rising star is given an 'experience score' out of 100, which is calculated on the number of minutes they have played for club and country. And 20-year-old U.S. starlet Pepi, who plays for PSV Eindhoven, is at number 10 on the striker list with a score of 73.4 and 2,521 minutes of game time. Manchester United forward Rasmus Hojlund, 20, tops the list at 88.9 and 3,298 minutes, Brighton's Evan Ferguson, 19, is second with 88.4 and 2,831 minutes, and Real Madrid-bound Endrick, 17, is seventh with 73.4 and 2,766 minutes.
