It's not diving just for pens either, remember the Vinny thunder bolt against Leicester season when Liverpool were playing Newcastle and Salah dived for a free kick late on well outside the box when the game had draw written all over it and the cnuts went on to score from it.
Thankfully at the end of the day they never benefitted from it as we went onto win the league by a point.
But that small cheating margin could have cost us
I think he did the same the season b4 against Newcastle to cheat another pen.
