I can see a Premier League midfielder like Tiote or Fellaini coming in.
If Fletcher can't come back we will be seriously lacking energy and steel in the midfield. I just have a feeling Fergie won't sign a foreign starlet or Modric or any of the expensive names out there.
If Berba leaves then I think Fergie will buy a fourth striker too.
I think if berbatov goes we def need a 4th striker because if Rooney got injured we would be toiling with Chico and Danny who are great as 3rd and 4th choice who could really improve but Utd should have a couple of top options in this position IMO
