You say that but core of the team playing that system now at club level anyway - Rooney, Ferdinand, Terry, J. Cole, Lampard, A. Cole, Hargreaves - so maybe wouldn't be such a problem now. Least would mean we can use the strengths of both Lampard and Gerrard at same time by adding Hargreaves in there to cover for them.
As for Crouch - just dont think he's good enough - yeah he has a good goal scoring record at international level but all his goals have come in a few games against, to be frank, shit teams. Would have him in squad as his height gives an extra option but wouldn't build an attack round him.
