I've said before that I want us to remain with more or less the current squad, as I think it'll help and the players we have are good enough. Assuming everyone heals up, we would have:
GK: EVDS, Foster, Kuszack, Amos
RB: Rafael, Wes Brown
CB: Evans, Rio, Vida, O'Shea
LB: Evra, Fabio
CM: Fletcher, Carrick, Hargreaves, Anderson, Gibson, Possebon
SMF: Nani, Tosic, Park, Ronaldo, Martin
FW: Berbatov, Rooney, Tevez, Welbeck, (maybe Macheda)
That's a pretty reasonable squad imo, with the addtion of Llajic (who looks pretty good) in January, and maybe a few other youngsters (Eckersley, James) coming through.
Most useful person we could get would be a defensive minded utility man in the O'Shea mold (but good) who could play across the back 4. We didn't adequately replace Silvestre tbh.
