Real Madrid star Cristiano Ronaldo has refused to bite back at Chelsea boss Jose Mourinho.

Mourinho had a dig at the Portuguese over the weekend, describing the Brazilian Ronaldo as the 'real Ronaldo'.

"There are things in life that do not deserve commenting on and that's one for obvious reasons," said Ronaldo. "I've always respected my coaches wherever I've been and I'll take only the good things from them.

"I always try to learn something from them.

"Speaking of people who speak badly about me ... I'm used to. In Portugal you usually say this: I do not spit on the dish I eat from. I keep things positive."
