Arsène Wenger would advocate longer suspensions for players who commit 'violent' tackles.
The issue of two-footed challenges has been in the news this week following red cards for Arsenal midfielder Denilson at Blackburn and Liverpool striker Peter Crouch at Chelsea.
Wenger believes that referees take a dimmer view of two-footed tackles - even if they do not inflict injury - than challenges from behind. However, he had no complaints at Mike Riley's decision to dismiss Denilson in the Carling Cup tie at Ewood Park.
"I find now for example that two-footed tackles facing the opponent are punished much more than tackles from behind," said Wenger. "For example Denilson got injured and got sent off.
"If you look again at the tackle he should not have done it but it was not a dangerous tackle. Then again so much was made of it straight away that the referee had no other option than to send him off.
"Tackles facing the opponent are punished much more than tackles from behind. I believe three games is enough but if it is complete violent conduct then I think you should be able to give more."
