You can're really call it "change" when he hasn't been with any other "clubs" yet.Doesn't he have to have magyar citizenship to play for the NT? So it must be dual then. He doesn't speak magyarul so that's a strike against him. Surely we can use him on the pitch (a definite starter), but this is not like changing clubs, which it feels a little like.
Also, he does speak magyarul, just not very well.
