It was virtually a carbon copy of the Mane one at Leicester, there was initial contact and then the player dived to win the penalty.It wasn't a dive either... The guy fell on Son's ankle.... Sometimes you have to roll with such a thing to avoid injury.
It should have been a pen.
The difference is the Mane one was given, I think we all know why. Klopp is the new Ferguson, Liverpool even benefit from Fergie time now.
I don't think either was a pen, due to the exaggerated dive, but one got given ours didn't which is starting to feel very familiar, there is zero consistency.
