the first thing he has to do, is to find a good goalkeeper!!
Scott Carson is a good choice, but he should find a way to boost his confidence by playing a few easy games for the England squad

bringing Jamie Carragher back would be a good thing too!!!
the midfielders and forwards are all great players so he doesnt need to change anything, he just got to hope that nobody is injured!!!
beckham, hm.. Capello made the mistake once already leaving him out the squad in Real Madrid and they almost lost the Championship, and Becks proved against Croatia that he is still one of the best midfielders in the world!!!
