Unless Santon is injured, not sure what's going on with him atm
The only area of debate for me was the two holding mids, I think with any combination of Tiote/Sissoko/Colback you're gonna have the problem of moving the ball forward to the attacking players, you need a ball-player who can link the defensive and attacking units and I think the only player who could do that is Anita
(Assuming a 4-2-3-1 which most people seem to have gone with)
