Schneiderlin and Gana for me should both start though. Not every game obviously but in most.
It's nonsense that they don't work together. They're not the same type of player and compliment each other well.
It's what's in front of them that matters.
The best we've played this season was that first half vs Split.
We had a balance. Klaassen was making some brilliant runs past Rooney and Mirallas and Lookman were stretching the game, with Gana sweeping up and Schneiderlin running it from deep.
Now, we can't play like that in every game, but we need at least one winger on the pitch if we go with that system.
If we go 4-3-3, then we don't go with wingers, we go with 3 of Rooney/Kev/DCL/Sandro/Lookman/Vlasic etc, and then utilise the midfielders as a flat three with a 'link' player as one of them (i.e. Sigurdsson as a playmaker).
In the latter formation, the width needs to come from full-backs, which is why Kenny needs to be given a go as well.
