He's just coming back from ACL while playing in a lower league. Give sometime, his pace and quickness will be regained.
And anyways, we need him to play against Mollorca & Las Palmas. He would do fine with what he has now. And I hope he becomes better.
I am not against the guy. Quite like that he's Assyrian (one of the most persecuted people in last 1500 years) and he seems to have already made friends in the dressing room.
