I agree the diving and play acting and 'win at any cost' attitude is there to a certain degree with all teams... but certain teams are far more prevalent at it and seem to get rewarded for it far more often.I agree, all the scrutiny on the City penalty, but the scourge of diving/playacting is there to see with all teams.
The "do anything to win" attitude.
(hint, those 'certain teams' both happen to play in red)
