Cristiano Ronaldo's "arrogance" makes him a target for opposing defenders, according to Arsenal boss Arsene Wenger.
Hitting out at the rise of rash challenges in the Barclays Premier League of late, Wenger used the example of the Manchester United winger as a player who does not always get enough protection.
"Sometimes I feel Manchester United get too much protection and sometimes they don't get enough and Ronaldo is a specific example of that," Wenger said. "Sometimes his arrogance is provocative - and his class as well."
He added: "But when a player is not protected it's not right. When there is a bad tackle you have to be punished and get sent off the pitch."
Ronaldo was in the wars again during United's 2-1 win over Newcastle at St James' Park on Wednesday night, clashing with Alan Smith on the pitch and then reportedly being involved in a tunnel bust-up with Steven Taylor.
Wenger has been concerned by a rise in reckless tackles this season.
Wigan's Lee Cattermole saw red on Wednesday night for a lunge at Scott Parker, while Everton confirmed on Thursday that Victor Anichebe will miss the rest of the season as a result of a Kevin Nolan tackle on January 22.
Wenger wants to see longer bans of up to 10 matches introduced for guilty players, claiming three matches is not enough when the victims can be sidelined for so long.
"They could create a special committee to analyse if three [games' suspension] is enough or not," he said. "I feel in some tackles 10 games is not enough."
