I think to get the best out of Mainoo he needs to play in a midfield three, and not one that includes Bruno Fernandes, who is more of a traditional 10 then he is a midfielder. If he played with, as an example, a midfield three of Toni Kroos, Kante and himself I think we would see the best out of him, all different styles of players that would compliment each other and each bring something different to the midfield. Not sure where he will fit in with Amorim's system, but I certainly don't want to see him leave, he's young enough he can adapt to Amorim's tactics.
