Realistically, once Coleman and Baines are healthy, what are we looking at as our best XI (with subs) after the window?
Mine would be:
Pickford
Coleman Holgate Williams Baines
Rooney Gana
Walcott Sigurdsson Vlasic
Tosun
Subs: Davies, Lookman, Keane, Kenny, McCarthy, DCL, Robles
That notably leaves Sandro, Klaassen, Schneiderlin, Jags, Lennon, Bolasie, Niasse, Besic, Baningime, and Funes Mori not even on the bench (Martina is not notable). With everyone healthy, the squad will be far too big for just the PL.
This leads me to think that we will definitely need to do more business this window, and that we desperately need to loan several of those younger players away to lower-tier PL clubs (or competitive Championship sides). My preferences would be Lookman, Baningime, and Sandro.
We also need to trim some fat. Jags really does seem past it, and with 4 other CB ahead of him, I think he needs to be moved on or take a coaching job (preferred). I no longer rate Schneiderlin due to his inconsistency, and think we could move him on for close to what we paid still. If we loan out Lookman and Sandro, I think Bolasie can serve as a valuable backup. Lennon should move on, as should Niasse and Stek.
Any cover for injuries after that can be taken care of by youth (though I'm not sure this is possible since most are out on loan already, but whatever, we're shit anyway and square pegs in round holes).
This is not to say that the starting XI above is good enough to break the top 6, but I no longer think that's possible this season, and we'll need to do much better business this summer than last to have a chance at a decent 2018-19 season.
