If you have seen quite a bit of him, he must have played a fair amount of games for a 4th choice CB, no?I have seen quite a bit of him and he is prone to errors or at least concentration lapses. Thankfully we've not seen any of that so far, but I do think it's still in him. He was 4th choice at Dortmund for a reason.
Judge a player after a season rather than a few games.
Last 4 seasons in Dortmund he played 25, 29, 28 and 26 games, again a solid amount of game time for a 4th choice CB.
In the champs league, he played 5,6,7 and 6.
Dropped because he would not sign a new contract and was now in his last year.
