Mesut Ozil is the latest player to have transfer documents leaked online, with details over his mega-money move from Real Madrid to Arsenal appearing on the web.

Similar to the one that Arsenal had with Cesc Fabregas - one, they of course didn’t activate. You can see the full breakdown by visiting GiveMeSport.com/Mesut-Ozil. Moving on, Arsene Wenger believes Diego Costa exploited the situation to get Per Mertesacker sent off during the loss to Chelsea this weekend. Wenger said Costa was good at doing such things, though refused to officially accuse him of anything.
