Yeah no chance Benzema will leave, that would leave them without a recognised striker. Ronaldo can play there, but yeah, that won't happen. Ozil said a few days ago that he won't be moving, that only leaves Di Maria, apparently they accepted a bid from Galatasaray but he didn't want to move. Arsenal could probably get him, but is he really what you need? For me it would be a striker, central midfielder, lots of help in defence and a keeper.
