I would say Bale tops this season's dive category with Welbeck in close second. But that is only because Young has not been playing much this season. If he was, he would be in second place ahead of Welbeck.
I can recall twice, which I would say more than enough, but that's hardly enough to get a mention on the worst British diving list
Gerrard is the worst, mostly because he will sit and talk about how diving is terrible and how he'll never do it, only to dive the next game.
Little known fact: Steven Gerrad never dives, except when hes diving Hes the English Suarez [video=youtube;i1jvUjuzKn8]http://www.youtube.com/watch?v=i1jvUjuzKn8&feature=related[/video]
He used to be awful for diving, but I can't remember him diving blatantly for at least 2-3 seasons now. He's been took over by other british players in that time. Bale is obviously the worst out of that list.
