Many of arsenal fans hate Ozil so much, yes it is acceptable! but i share a little different opinion, I can bet Ozil be better with time. I hate van persie for his lack respect to a club who were patient with him till he peaked, but bring him or his equivalent for Mesut and see the difference. Ozil is not a defender or defensive midfielder, though teamwork demands that of him, he should not crucified for that, but rather of his failure upfront!
I support Ozil 100%! His kind of game require quick reaction upront, but look who is there to do that, no one? Giroud is slow so as to Sanogo, the only player who could unleashed the potential in Ozil is Theo.
