Leave Ashley Young Alone!

I wish people would stop crying about how Young dived, it was 4-0 for pete's sake! United had that game in the bag either way. And the game before, it was the referee's decision. How can anyone expect players to stop diving unless anything is done with it? Why should Young not dive when it could get his team a penalty, that could get his team the 3 points, that could win his team the title? He shouldn't, it's part of the game, and it needs to change. The people at FIFA need to do something about this.
I have suggested a challenge system in a previous post (here: http://unitedfanatic.blogspot.com/2012/04/my-take-on-diving.html), I feel this, or anything similar to this will benefit the game greatly and prevent crying supporters. All Young is, is an ambitious player in his first season at United, and is trying to help the team his utmost to get some silverware.
Diving is ruining the beautiful game, and people can sit around whining about players diving, or FIFA can do something about it, and I hope they decide to do so. Bring back the beautiful game!
And besides, the only reason Young's dives are under so much scrutiny is because he plays for the best club in the world, Manchester United. Everyone is just doing the utmost they can to gain an advantage over United, and if it means trashing the players in the media in hopes they will play bad, let them do it. Young is a professional, and a VERY talented player, this talk will not phase him in the slightest!
Some of the all time greats of the game have dived, hell, I'd even go as far as to say EVERY player has dived at least one time in their career. Some players who have dived are Messi, Beckham, Ronaldo, Nani, Gerrard, Lampard, and the list goes on and on.
So, what do you guys think about this? Is Young wrong for doing it even though everyone else does? Does FIFA need to step in?
