Wenger has reopened hostilities with Manchester United
Manager Arsene Wenger has accused Manchester United of adopting "anti-football" tactics during Saturday's 2-1 victory over his Arsenal side.
Wenger also claimed referee Mike Dean allowed the champions to "repeatedly foul" Arsenal players during the match.
He said: "I have seen a player make 20 fouls without getting a yellow card.
"If you have seen the game, you don't need me to tell you who but their player gets away without a yellow card. It's quite amazing," stormed Wenger.
After a 2-0 defeat at Old Trafford in 2004, Wenger claimed United had directly targeted his players.
This time, the Arsenal manager said the home team's approach went continually unpunished by Dean.
The referee, from the Wirral, issued nine yellow cards during the game, with six going to Arsenal, who will now face a Football Association fine for failing to control their players during the fixture.
But with United midfielders Darren Fletcher and Michael Carrick emerging from the game without bookings, Wenger claims that persistent fouling has now become a greater problem than diving.
That has become a hot topic again following Uefa's decision to charge Gunners forward Eduardo for simulation during the Champions League victory against Celtic last Wednesday.
Another Arsenal player, Emmanuel Eboue, was cautioned for diving on Saturday.
But Wenger said: "I have seen today a player [Eduardo] who plays only on the pitch, but there are other points that for me are more urgent - players who play only to make fouls, who make repeated fouls and are never punished.
"They get out of the game without a yellow card, but I think it is more anti-football than a player who did what Eduardo did.
"I have seen a player make 20 fouls without getting a yellow card. If you have seen the game, you don't need me to tell you who but their player gets away without a yellow card. It's quite amazing."
