Yennaris was much better than Djourou against United
Vermaelen has been playing left back for a while and even though it might be better for him to stay there but Miquel can play left back and I'd rather have Vermaelen in the center than someone like Squillaci.
Song deserves a break, he was not as good as he has been against United.
Rosicky has played well in the center midfield. Benayoun can play on the wing to help Yennaris. The Ox should keep on getting starts until Gervinho comes back and I think it's time for Henry to get a start if he's healthy.
Other variations can change Rosicky with Benayoun or do that and put Henry on the wing.

or switch Van Persie with Henry if RVP wants to drop back a little bit to link with the midfield like he likes to do
