Portugal winger Cristiano Ronaldo has vowed not to react to provocation with Manchester United.

The 22-year-old has served a three-match ban following his dismissal at Portsmouth, where Sir Alex Ferguson criticised the Portugal international for being provoked - and Ronaldo has insisted he will no longer retaliate on the pitch.

He told the Daily Mail: "I´ve learned a lot from this punishment. Now I am mentally prepared to tolerate anything my rivals throw at me. They cannot provoke me any more."
