Barcelona goalkeeper, Marc-Andre ter Stegen has asked his teammates to be wary of his countryman, Mesut Ozil as the assist king is capable of doing the unthinkable.

Speaking to the press ahead of Arsenal’s clash with the Catalans at the Camp Nou tonight, the skipper who played alongside Ozil  said ‘As a footballer, Ozil is a player who can do unthinkable things, just like Messi,’  ‘He is impressive, and we will have to be alert that he does not harm us. I have played with him two or three times and he is a very significant player for the German national team and can do incredible things.’
