Seems likely that we go for Sesko in all honestly. I don't mind him, but he's still very young and his goalscoring record is decent but not spectacular. He'd be an improvement on what we have now, but is that improvement significant enough to win us major honours? I'm yet to be convinced.
Isak is the dream, but Newcastle's asking price (understandably) is too much and I don't see them budging, especially with 3 years left on his deal and them fighting for a CL place currently.
Kudus would be a good signing, however, can't see West Ham letting him go for less than his release clause (£85m) and he's definitely not worth that.
Cunha I'd be open to signing - providing it's between £60m-£70m. But he's not a level-raiser, he just improves the depth of quality of our squad.
As I've said previously, The Athletic were saying that we're apparently not convinced by Gyokeres and not likely to pursue him, so I think this one isn't likely.
