Yeah he definitely hasn't lost the players, all i can think of he has been making them play rigid and stifled because of how bad the defence has been. Havent made risky runs or forward passes like this all season.
The only possibility for this game to not end 0:0 is Martial. Chelsea is toothless (could score from a set piece of course) and every time United creates danger it is because of the young Frenchman.
