If Ederson didn't Rush out, Lukaku simply has a one v one. Ederson did the right thing. He was aggressive. He simply didn't get to it.
It wasn't going out wide, Lukaku knocked it wide to get it away from Ederson. Komps and Adarabioyo were both trailing a few steps behind. The error was Kompany losing track of the ball in the air as Lukaku runs past him.
We lost the ball upfield Kompany still I g so deep kept Rashford onside. He had no reason to drop that deep. He doesn't do that and Rash is offside.
Blaming Dihno who had gone up to attack when we lost the ball upfield, presumed we don't have a plan for when fullbacks overlaps and we lose the ball on transition. We actually do. Failure to execute that plan correctly is what makes it Kompany's fault
