What I will say is that if you take one player from the usual front 4 (Mata, Mkhitaryan, X & Ibra) then it seems to take so much of the fluidity and inventive thinking out of it. In this case there's a player missing from it for formation purposes. Zlatan looks like a frustrated figure at times when he hasn't got a #10 near him with runners off him, especially against deep defenses like this. Ok, Valencia and Blind are doing well to stretch the game and fire crosses in, but it's going to take one **** of a ball to be a goalscoring one with Ibra a lonely figure in there. I still think we're at our best in a 4-2-3-1, playing quick one touch football in and around a front 4, with plenty of bodies in and around the box.
Something simple like Rashford for Smalling/Bailly/Rojo, go 4-2-3-1 with him, Mkhi and Mata playing off Ibra would add so much I feel. But against this oppo, with the control we currently have, I wouldn't argue with Jose letting it play out and try get the goal(s) from somewhere.
