OK, something you need to change.
1. Where you have the U21 team, they have different stats to the player in the club. Example in Italy U21, Giovinco is a SS with different stats and a built face compared to Juventus where he is a AMF with different stats with a Cristiano Ronaldo face. This is the same for most of the players in the U21 teams.
2. While I was checking the first point with Pato, I noticed Luke Moore in A.C Milan.
3. Also in the England U21 side, in midfield I found Platt, who is 28, who is originally in the Classic team. Probably because you didn't notice him.
Any others I'll let you know.
This is with the V 4X.
