Manchester United winger Cristiano Ronaldo has admitted he needs to improve his reaction to challenges following a series of high-profile incidents this season.
The Portugal international was involved in a flare-up with Newcastle United defender Steven Taylor last week and has been widely criticised for petulant kicks at Stoke's Andy Wilkinson and Michael Dawson of Tottenham this season.
"I am a target of course, so it is difficult to avoid certain things," Ronaldo told The Sun.
"I try to control my anger. Sometimes it's not easy, though, and it is something I have to improve on.
"Sometimes it is difficult because of the atmosphere in the stadium and the importance of the game.
"I'm only 24 but I have a lot of experience of big games and that helps because you learn through situations.
"If someone kicks me, I get up and I go again. I am not afraid of being kicked, it is part of the game.
"I see it as a challenge that they have to kick me to stop me."
