I think what we need now is a striker that can score goals like Villa and a winger who is verstille can play anywhere in midfield which adds more flair creavity and can score goals aswll like Silva.

These two players are the ones that we need the most

The arrival of Ljajic will be very important to us and return of Hargreaves. I hope when he reaches he's fit and doesn't need too much time to adapt to the EPL.

With Ljajic (A creative AM) and Hargreaves (A DM)  we'll have alot more options.

Imagine this side:

Formation (4-3-3)

                  VDS

O'Shea  Ferdi   Vidic   Evra

                 Hargo

        Fletcher    Ljajic

 Valencia   Berbatov  Rooney

Or

Formation (4-4-2)

                VDS

O'Shea  Ferdi  Vidic  Evra

Valencia  Hargo Ljajic Giggs

          Rooney

                 Berba

This is obviously when we don't play our midfield partnerships like : Carrick-Ando, Carrick-Fletch, Ando-Fletch. With two more midfielders we'll have so much depth we can strategize for any match.
