I just think the best bits of players like Mainoo are accentuated with another on the same wavelength with similar technical ability. Scholes/Carrick, Iniesta/Xavi, Gavi/Pedri, Modric/Kroos. You simply cannot get the same thing from Mainoo/Onana or Bruno. We could have easily said ‘we need someone to win the ball next to Scholes’ and gone Scholes/Essien - which would have some advantages, but would lose a lot of what Scholes can do.
This only works if the pair are very top players of course, and the two in question here are two of the very best amongst the young players. We can get a proper control of football matches with this sort of duo, with silk then being our natural game as opposed to Mainoo providing moments of silk in the midst of chaos. We would need other profiles, so the two of them ahead of an Onana in some games, or behind a 10 in others can work.
I think a lot of us have said for years that we want to move away from being a side of moments, but at some point, these are the sort of decisions that need to be taken to change the OS of United. I think both Mainoo and Neves do enough creatively between them, and defensively between them - but the third midfielder can vary from game to game and tip the scale more defensively or offensively. Even before Neves’ brilliant season, I had been excited by the prospect of Dan Gore developing alongside Mainoo. I do think teams need to go for it and get two of these types though to maximise. You can’t drop Xavi in a Stoke team and just expect him to pass and move, to use an extreme example.
