Assuming no core players leave (which they might, or might not?), i think we critically need:
Right Back
Defensive Midfielder (solely due to Kamara's ACL injury - he wont be back until nov/Dec, and wont be fully fit until new year 2025, so we defo need one)
I can see Digne leaving in the summer, so thats a left back we need if he does.
i can see quite a few outs in the summer, if we can offload them (or we end their loans/dont try to purchase them), like Olsen, Hause, Digne, Chambers, Dendoncker, Coutinho, Zaniolo, Lenglet, Coutinho etc
Anything else is just nice to have's i think, such as a forward capable of playing across the forward line, and maybe another striker, depending on what happens with Duran in the summer.
