Capello could be good, he's arguably the best club manager in the world (best record at least), though he's not got the pedigree at international level. Either him or Otto Rehagel - if he can win Euro 2004 with Greece then he should do well with England.
I think we should play more like Man U, play more on the counter and use two defensive midfielders who can play a bit ie Carrick with his range of passing, and Hargreaves with his tenacity. That's what Croatia did to us after all and it's what a lot of non-British teams do, it's less risky, but the football can be attractive on the break at least.
