Manchester United manager David Moyes has called for video evidence to stamp out diving after revealing he has told Ashley Young to cut out the theatrics.
Young was booked for deliberately initiating contact with Crystal Palace midfielder Kagisho Dikgacoi in a failed bid to win a penalty in Saturday's 2-0 victory at Old Trafford.
The United winger was then bundled over by Dikgacoi in a separate incident later in the half which brought Moyes's team their first goal of the day via a penalty and led to the Palace player's dismissal.
Moyes felt referee Jon Moss handled the situation perfectly, but he was quick to condemn England international Young for his dive and made it clear the use of post-match video to prove players guilty of diving is the best way to sort out the issue.
"I have had a word with him (Young) privately. I can never be sure it won't happen again," Moyes said.
"I've said for many years we should have retrospective video for diving. That would help referees no end.
"Moving from Everton to Manchester United doesn't change my views on that because it is really difficult at times."
Palace chairman Steve Parish has gone even further, claiming diving should be treated in the same harsh manner as preventing goalscoring opportunities.
"If preventing a goalscoring opportunity is a straight red then trying to create one by cheating should be a straight red also," Parish told BBC Radio 5 Live.
"The only player in the incidents that was honest was Kagisho Dikgacoi and he's sent off and banned for the next match.
"Ashley Young's dive and the appeal before put pressure on the referee to give a subsequent penalty that was certainly outside the area and probably wasn't even a foul.
"Ashley Young has a yellow card and three points and we have no points and one less player to pick from for the next game.
"It might have cost us a point that might keep us up. We need to get some momentum behind a straight red for a dive."
