If it's a straight choice between Zubimendi and any other midfielders we have been linked with. I'm picking the former. Like Ugarte, I don't think he is the perfect Mainoo partner, but unless we are signing Rodri, that's not going to happen this summer.
Zubimendi, Ugarte, Mainoo, Mount would give us a hell of a lot of options for those two spots. Use Gore/Collyer or even Eriksen if he doesn't want to leave as 5th choice.
Obviously a huge ask, but I do feel like we have some players who do have value. McTominay, Casemiro, Mejbri even throw in Pellistri. Could we get £60m for them? Add it to the Van de Beek money, gives us £60.5m. I'm not sure how the finances work, but with the wages saved, surely that would be enough to bring in 2 players?
