Thats not true man.
We had Morata playing separated from the team, wich caused great problems for bayern. If they pushed high, he would win the race for the ball and he's able to controll it and score. So they stayed deeper, and he'd still controll and lay off to supporting players.
We needed to do this, in order to keep their press away.
When morata went off, we should have fielded a substitute who did exactly the same. Instead, mandzukic came on, all danger for the counter over the defence was gone, so neuer played sweeper and the defence moved 30 meters forward and we got effectively in the press
khedira's ball retention going out for a weak sturaro, and a magnificent cuadrado going out for a bleak pereyra obviously didnt help, but we had no choise
