Mane and Salah apart from the theatrics are brilliant players no doubt, but what helps them enormously is the fact, defenders know they can not get too close to them, as they know the result, a penalty. They know the slightest touch will mean they scream, throw their arms up in the air and collapse in so called agony, which in 9 times out of 10 results in a pen. They can say everyone does it, but nobody does it better and referees seem to want to fall for it. Sickening thing is the media commentators seem to accept it with glee, until they start questioning it like they do with other teams players, they'll continue to do it.
