I wasn't there when Cahill slotted in his header, but remember it fondly.
I think this game will be an improvement on the Arsenal performance and I would expect to see Yakubu start. Funnily enough, I wonder if Moyes might start with two up top?? We seemed to create a lot of chances when more strikers came on against Arsenal, so don't be surprised to see a 4-3-3 with Cahill sitting just behind two strikers (so probably more of a 4-3-1-2).
Arteta keeps his place in my mind and I think we'll see a different game from him this week. (I wonder how much of playing against Cesc was playing on his mind in that game??).
All that said, a draw would be taken right now if offered as they will be in a boyant mood as will their fans. Expect a large crowd for this game.
