If we had signed him alongside a top quality player, it would have been a good bit of business. However, given the only other midfielder we've signed is Benayoun, it's an underwhelming signing.
But then again, he will be playing with Wilshire, Song, Diaby, Arshavin, Walcott, Ramsay etc etc. Don't care waht anyone says...they're still very good players on their day.
