Come on now is diving new? just watched Newcastle and Robert just got a penalty for a blatent dive, not the first this season, and as commented on by the commentator from sky Newcastle have been given more penaltys then any other club with Robert at the centre of most of them. Its part of the game like when any player fouls another in any part of the pitch he is trying to gain an advantage ie cheating, diving is just part of that
, so if your team plays the whole game without giving away a free kick then you can criticize someone for diving.
