I don’t think we need another midfielder unless Pogba goes. Bellingham if it happens will come regardless on if Pogba stays or goes. If Pogba leaves then Grealish will most likely be a prime target. I think a CB is needed especially since Jones and Smalling will likely be leaving. I think our signings will be Ighalo, Sancho, Bellingham and a CB. Got a feeling Pogba will stay.
Even if Pogba stays, i'd still class a midfielder as more important than a CB.
Maybe not Grealish, but a natural DM to replace Matic in a years time.
Outgoings should be:
Lingard
Sanchez
Smalling
Rojo
Jones
Pogba (unlikely but best for all concerned)
Incomings:
Ighalo
Bellingham
Sancho
Zakaria
Grealish (If Pogba leaves)
We'd have good options for CB:
Lindelof
Maguire
Tuanzebe
Bailly
Fosu Mensah (if needed/backup)
On paper, selling 3 CB's and signing none seems a bit odd, but 2 are already on loan and one's featured 8 times in the premier league with only 2 starts. We're just selling players who don't contribute anyway
