What I have observed during multitude of matches we have played against Liverpool, it's so difficult to bully them off the ball anywhere on the pitch apart from the two boxes. Everyone saw with Diaz on Sunday, it was same with Mane, Salah etc earlier. So tenacious and hard working.
But everything changes once the ball reaches anywhere near the penalty area, each one of them become a very unstable stack of zenga. One slight touch and they just collapse. And it happens in both the boxes. You saw with Allisson against us, Konate against Forest (both in their own box). Less said about the penalties won in the opposition boxes the better.
I guess diving means more to the Liverpool players and management staff!
