Everyone hates Olivier! Sounds like a sitcom.
He's a 6' 4" monster (in a sport chock full of sub 6 footers) and he's pretty darn good. The real problem, is that he's not at the top of the pyramid (e.g., Neymar, Ronaldo, Bale, Aguero, Lewandowski, et al). And that's largely why fans hate him.
Agreed. His movement inside the box is about as good as it gets IMO. So many of Arsenal's goals come from him fading to the back post or darting toward the near post. If you have players who can get him the ball, he's going to succeed.
