I think I have seen cases of acting so blatant in soccer that someone will allow a stretcher to take them off the field before miraculously running back on? There should be some rule about that... If you're injured enough to beg for a penalty, that's fine... But you need to spend the rest of the game in hospital!
And a few weeks ago that Aussie scrumhalf did a soccer/Oscar worthy job playing up his severe agony as well.
What happened to "Soccer is a game where everyone pretends to be injured, and rugby is a game where everyone pretends NOT to be injured"?
