Yes we need a defensive midfielder more than anything else, but with all the injuries our priorities changed, with Cesc, Rosicky and Walcott all out, we are in dire need of creativity. Arshavin will probably be played on the wing even if its not his best position. But he's a better option there than the likes of Diaby, Denilson and Eboue, frankly i'm tired of seeing those mediocre players on the wing.
