Haaland is the overwhelmingly obvious choice of course, and beyond him, I can’t see much. Calvert-Lewin perhaps, Lautaro looks like extending at Inter. Harold Kane will be impossible to get. On the whole, there aren’t many strikers we could realistically get that will be an upgrade on Martial. We could easily improve on Martial of this season, but even if some don’t want to admit - he’s obviously not a 4 goal striker, and is in a low period now.
If we can’t get one of a very small group of strikers who may be available - then I think we’d be best served going with Martial again next season and hoping his form improves, which it is obviously capable of. We’ve watched him for enough years to see that this isn’t his limit, once emotion is put aside.
