If he replaces Sigurdsson or Dembele, I would say that would make sense. but we don't just need to add more players to an already packed area of the field. I agree there are other areas that need addressing first, but I think we have lacked a bit of creative spark in midfield, something will need to be done about it. I think that we have missed that bit of special creativity to make things happen further up the field.
Saying that I can't see us paying out for him as well as solving the other problems, so probably just have to see what happens after the world cup.
