I can see Tomori back, but it really depends how hard Chelseas transfer ban hits them. He could easily be a bench-warmer/late game replacement for them if they are short on numbers. I fully expect to see Mount in and around their first team - he's too good not to be, and it's been a privilege to watch him play.
Wilson i'm not sure on. He would suit a Palace or Newcastle, but he has come on a lot this year so they might decide Frankie is best for him. Who knows.
I'd love to keep all three, and maybe even add Ampadu, but that's probably wishful thinking.
