I'd still keep Kagawa and use him as player swap if required for Gundogan. Definitely get rid of Young next window. That would leave us with a nice variety of players in the final third ranging from wingers and CAMs. Get Gundogan and one other CM with ball winning abilities. Move on Ando and perhaps Cleverley permanently. Get Coentrao or break bank for Shaw at LB. Lastly a good experienced CB for Rio. Ideal lineup for next season would be:
RVP
Januzaj, Rooney, Mata
Gubdogan, Carrick
Shaw, Vidic, Benatia, Rafa
de Gea
If we could pull off the Mata deal, being before the world cup, it's one less worry.
