No, I didnt miss that. What you probabaly missed is that when Mousset closed people down, he didn't run around like a headless chicken, he was supported by McGoldrick and either Fleck/Lundstram. I'm not sure how many times this has to be said, but pressing isn't something one man can do, it's a team effort. If at the point where Didzy is blowing, and Man Utd are starting to move higher up the pitch, McBurnie just starts racing up to whichever player has the ball, it's not pressing: it's just one bloke running around, chasing the ball.
We dont press for the full 90 mins in any game we play, we might tire, lose confidence, the opposition might player higher up the pitch, or begin to break the press. There's a multitude of reasons why we sat deeper and stopped pressing yesterday and I can assure you, McBurnie coming on was not one of them. It's very revealing that McBurnie is the only one singled out for not pressing, despite it being the responsibility of the team - smacks of looking for a scapegoat to me.
