Plan B??
Seemed to work on Sunday against Citeh....
And you are correct on the defensive issue. We can't carry any passengers. Arshavin may get away with it against a Coventry, but I wouldn't trust him against a team when it requires the work rate that Cazorla, Arteta and Diaby/Ramsey/Coq have given us thus far.
I don't think anyone is doubting Walcott as a player, necessarily. Though we may have ideas on his relative strengths and weaknesses. It's more about finding space in the side for a contractural headache player (his fault or ours, or both), especially when he wants one thing, and the team requires something else.
For me right now, the only berth open to him, is the one currently occupied by Gervinho. And he'll get his chance there sooner or later.
This bollocks about playing him as an Ian Wright is outdated, and needs a Grioud or Chamakh or Alan "Smudger" Smith alongside him....and if you play 4-4-2, you better get used to us losing the midfield battle, ditching possession, and playing like Stoke.
