I'd still take Arshavin (the chances of us signing him now are slim, but he may be available in another transfer window), even though he'd be forced to play a slightly different role given we now have Keane. He'd fit in the side in a 4-2-3-1 without any bother, on the left or right, or behind Torres.
Mascherano
Alonso
Gerrard Keane Arshavin
Torres
As an aside, I can't believe Zenith paid £25m for that Portuguese bloke Danny, and from another Russian club?
