It seems my player is not worth the 24 tokens. He gets 40/70/120 for training but during competitive matches he averages 100-110 despite always getting 7 rating +. I don't understand because my other guy who was signed for 12 tokens is getting 300+ skill points/match. It would help if the more experienced managers with vast knowledge of the U21 could answer. As conclusion to this small experiment, it's a waste of tokens and time. I already started training him and now I can't let him leave for cheap, the only plus side is he's a good trainer but he's too far off the team's average. CASE CLOSED!!!
