I guess a lot depends on Wilshere's fitness. I don't think Roy would take him though unless he planned on starting him, and I half suspect that Wenger may have been holding him back these past couple of weeks to allow for that. Seeing as the back four and GK pick themselves really, I would go:
---Gerrard---Wilshere---
Sterling--Rooney---Lallana
-----Sturridge----
I think Lallana would give us balance in that midfield, and I actually rate him. Retains the ball well.
