For me, for different reason we need to move on Davies, Tangaga, Spence, Sessegnon, Skipp, Hojbjerg amd Gil if possible, while being open to selling Emerson, Bissouma, Lo Celso and Kulusevski for the right price. Most of these are fine as back-up/squad players, but feel like the team needs a bit of a overhaul. The more we can get it the more we can bring in hopefully, though it won't be easy as it never is.
The backline is absolutely fine. It needs better protection from those ahead of it. The midfield will be better once Maddison and Bentancur come back into form, but we could still do with one or ideally two signings in that area. For me, it's the forward line that needs most work. Son is still fine, but not what he was. It's unfair on him at this stage of his career to expect him to bail us out time and again. Kulsevski just doesn't do enough often enough. Johnson is a work in progress. Richarlison I just can't see ever being the main man as much as I would love him to be. Werner I would probably keep as he's so cheap, it's a shame he got injured when he did.
