*** LOOK IN THE COMMENTS FOR OTHER FORMATIONS***
SIGNINGS:
Alexis Sanchez - Happening this window but sure I'll include him in this
Milinkovic-Savic - A lot of hype around him, perfect Mourinho player and looks a great talent. Also a physical beast and will solid up the midfield defensively.
New CB - Mourinho has openly said we are targeting a defender, at first I thought it would be a LB but Shaw is playing great, don't need a RB either with Fosu-Mensah balling at Palace. So I reckon he'll look a world class CB to partner Bailly. We haven't had a consistent CB pairing in a long while mainly due to Bailly's injury but Alderweireld would be an amazing signing.
New CDM - With Carrick leaving we have absolutely zero cover for Matic and as seen recently he looks really tired. Ideally a DLP like Jorginho or Weigl but they aren't the type of players Mourinho would sign so Fabinho, young enough to not mind a rotation role and then soon would replace Matic. Other options - Fred, Dendoncker, Carvalho, Danilo Pereira
Mesut Ozil - Now this isn't a priority but he will be available for free and he'd definitely be attracted to playing with Mourinho again and with Pogba and Sanchez. Big chance we sign in my opinion so that would be huge. He can RW, LW, CAM or CM in our set-ups. 
SALES: 
Rojo & Smalling (both if we sign a CB, one if we don't), Darmian (shite), Blind (average), Fellaini (looks to be rejecting contracts, thank fuck), Mkhitaryan (off to Arsenal). Herrera might leave with the possibility of 2 new midfielders but would like him to stay for depth.
