I found some mistakes at European teams:
Bosnia And Herzegovina:
Brtoric is Brasnic, not Begovic(He's Canadian in the game).
Baaine is Topic, not Bartolovic.
Montenegro:
Batiuja is Basa(Lokomotiv Moscow) and Barosi is Batak, they need to be replaced.
V. Bozovic, Drincic, Tanasijevic and Novakovic aren't double, because their teams in the game are fake.
Serbia:
Josarolic is Jovanovic(Standard), Jaslevic is Jankovic(Genoa), they need to be replaced
Korsevic is Kolarov(Lazio), not Kuzmanovic.
Kurtajic is Kuzmanovic, not Krstajic.
Slovakia:
Durica(Durka) is double(Lokomotiv Moscow).
Saket is Sapara(Rosenborg), not Svento.
Smalech is Stoch(Chelsea), not Sapara.
Cisovsky isn't double, his team in the game is fake.
Ukraine:
Rutolov is Rusol, not Rakytskiy.
Flanov is Khudzhamov(Shakhtar).
Wales:
Cheberton is Ched Evans, not Gabbidon.
Corton is Collison, not Koumas.
