Klaus, I only realized yesterday after you posted the Cerci compilation that he was actually left footed. I always thought he was right footed since he played as a right side forward.
I wouldn't be surprised at all if we are in for him.
I really don't think Wenger likes to play Ozil on the left wing but after two seasons he probably dislikes playing Cazorla there even more. Ozil has to play though and he keeps the width so Wenger has played him there.
If Cerci can play as the left sided forward with Sanchez in the center, Walcott on the right and Ozil feeding them, then we will have everything in that forward line.
