Plus, Arsenal relies on attacking full backs. Chelsea does not. He'd do far better at Arsenal.
We don't rely on attacking full backs?! Where on earth do you think we got our attacking width from in the last few seasons when we didn't play with an out and out winger?!!
Arsenal can go ahead and take him. He can't cross the ball, he slows down attacks and more importantly, he can't defend! His awareness and concentration levels are very very very average. IF you want to get the best out of him, play him at anywhere across the back four but RB. Kept Messi quiet when being played at LB and CB...
And oh, he wouldn't have started in the Champions League final had Ivanovic not been suspended for it.
