Ronaldo is a terrible actor: Against AC Milan in the Champions League Ronaldo he tried to get a player red carded as he acted like he was hit in the face. He even looks up to see if the referee is looking. Come on Ronaldo, you don't need to do stuff like this.
Ronaldo has a history of this though, remember how he suckered Wayne Rooney into getting a card in the World Cup, his own club teammate. But I thought Ronaldo had grown out of this type of stuff.
People always ask, who's better, Messi or Ronaldo, you'd never see Messi do something like this. Messi is a much classier player. Take a look at the video.
