Amusing though Burnley's win is, the penalty was given after an awful and deliberate dive.
In 2021 you're allowed to highlight to the ref that an opponent has acted illegally.
You can be red carded for flying in to someone and not actually making ANY contact, based on intent and recklessness.
Allison, does make contact, shouldn't fly into his path and rightfully it was a stonewall penalty. It was reckless, late and he made lots of contact with the player and none with the ball.
Plus, its swings and roundabouts with dives. I remember Salah getting tap on his ankle at West Ham? It was the type of kick you give to your mate when you''ve seen something funny and you want to get their attention. Salah then delays, and THEN decides to throw himself to the floor because he felt marginal contact.
Swings and roundabouts in 2021, don't give the ref the option to give a penalty. Burnley are well coached, and you could see they were not willing to swing legs at Liverpool in the box. That's how you defend in 2021, maybe Liverpool should take a leaf out of their book.
