I think that's ultimately where he will end up, whether he likes it or not. He's not a striker anymore, he hasn't got the positional discipline to play that role but he still has a football brain.
I would play him No 10 but we've just paid £45m for one of them.
There's probably room for 1 number 10 behind the striker
The striker is either DCL or Niasse I assume
The number 10 is either Rooney, Sigurdsson or Klaassen
Then there's 2 centre mids from Schneiderlin, Gana, Davies, Besic, McCarthy
And 2 wide players from Mirallas, Vlasic, Lookman, Lennon
Sandro possibly either the striker or a winger
For me if we followed these ingredients for the midfield/attack we would have a better balance
Massive issue at the moment is players are being shoehorned in regardless of if they fit in the system together or not
