GK, RB, CM & CF still in need of serious upgrading. Two players each required for the CM & CF positions as we are absolutely bare bones there at the moment. We also need another quality CB option considering Varane’s fitness issues.
Given Maguire, Lindelof etc. I think we're reasonably well stocked at CB. Lindelof in particular is doing just fine as the 3rd CB IMO.
CM: We have the numbers - Fred needs to go but McTominay, Eriksen, Casemiro are three reasonable options. We really need that FdJ type playmaker. That's the #1 thing missing from the squad right now. If we had FdJ, then Casemiro / FdJ or McTominay / Eriksen are reasonable midfield pairings.
CF: We have Martial, Rashford who can fill in there as backups. Don't think we need a second one if we have a proper starter like Osimhen.
GK: Yep, DDG will end his contract and we'll have to get a new GK.
RB I can go either way. I'm fine if we don't sign anyone next summer and focus on CF, CM and GK.
