Stepney believes players like Young would have suffered serious reprisals if they had tried the same antics in his era.
Stepney said: "If any player did that in our day, they would have got seen to. There are players in every team that do it.
"Now the only people that can stop it are the ref, the Premier League and the FA.
"They have to come up with strong punishments for diving and the only way you can do that is video evidence.
"The way they're doing it is not riding the tackle. They're throwing their feet into the other player to get the penalty."
