I've been one of those slating people for suggesting 442. However, this could genuinely be the game where Rafa chooses to do it. Either that or it will just be Colback and Hayden. Reckon Hayden will be the one given the licence to roam, if that's the case.
As always, it's Perez and Diame who worry me, I have no confidence in either.
Edit: if we go two up top, it will still be Colback and Hayden it's just I can see our play being more direct with Mitrovic and Gayle up front.
