You're delusional. Our problems start and end in the midfield. What you're seeing are merely symptoms of a problem, not the problem itself.
There's 2 problems and we only need to fix one.
Problem 1 is the midfield press died and we lost mobility. Problem 2 is the back centrebacks are too slow to play the high line when the opposition midfield has time on the ball.
If you solve problem 1, problem 2 is solved, as it was 2017-2019. If you solve problem 2, problem 1 is irrelevant.
