My order of priority is, and I doubt we'll sign all of these in one window - RM, CM, RB, CB, GK.
RM - We can't get away with just Walcott all of next season, my choice would be Buendia however I can imagine we'll sign someone I've never heard of instead.
CM - After Gomes it doesn't look great. Gbamin is a complete unknown. Delph has shown nothing to suggest he's the answer. Davies probably isn't good enough, but I'd keep him as 4th choice. Sigurdsson and Schneiderlin are on huge wages and offer almost nothing, sell both. Find us someone sexy Carlo.
RB - We can probably get away with Coleman and Kenny next year, but I'd rather us sign someone who comes straight in and improves us. Don't sign Sidibe. People seem to like Max Aarons but I'm on the fence.
CB - A long-term injury and we're struggling here. Need another CB in. Realistically we won't be selling Keane, so we need someone to come in and challenge Mina and Holgate. No idea who I'd want for this position.
GK - Too many clangers from Pickford, and he's got the second worst save % in the league after Kepa (19th out of 20). There are better goalkeepers in this league that'll be relegated this year. Dubravka (6th), Ramsdale (7th) and Ryan (10th) are all good keepers, as is Fabianski who has been injured for most the season so doesn't make the table.
And that's me done until the window opens.
