United and in particular Ashley Young have been at the centre of several diving controversies in recent weeks and Ferguson yesterday revealed that he has 'had a word' with the England international about going to ground too easily.
These incidents have led to calls for disciplinary action to be taken against those players who are found guilty of diving, but Ferguson does not feel that is realistic.
"The only one case I can remember of a player being retrospectively punished was Rivaldo. I can't remember another player ever being punished for acting," said Ferguson.
"It doesn't lie with the clubs, it is FIFA and UEFA. But there are a load of things we ask them for, including goal-line technology, and nothing's ever done.
"It doesn't bother me one way or the other, because I don't think it will happen."
United host Everton at Old Trafford in Premier League action on Sunday.
