Although it very rarely happens, I DO actually see us signing MORE than four players this summer. There is a strong possibility this summer we may lose DeGea, Ibrahimovic , Carrick and Rooney. Irrespective of where they are career wise both in terms of age and current ability that is four big name, talents and characters to lose. Add other possibilities with some of Mourinhos comments on Shaw, Smalling and JOnes and there could be England internationals leaving too. Then there are more hyped youngsters who seem to have failed from there loans in Perreira and Januzaj who I had high hopes for. And what about Blind, Darmian, Ashley Young? I wish I could add Fellaini to this list but hey
I think Mensah (as a centre back or even defensive midfielder, not a ruddy right back, stop playing him there) and Tuanzabe are both very much talented enough and seem to have the right attitude to play a more prominent squad role if there are outgoings. But without guessing I fully expect us to sign:
A top quality partner for Bailly (love him)
A central midfielder to partner Pogba
An attacking wide player
Depending on outgoings we may well also see:
A new left back
Another central midfielder to replace Carrick
A target man to replace Ibrahimovic
