Ronaldo shrugs off Boo Boys

Cristiano Ronaldo does not believe booing from fans at away grounds will affect his form.

The Portugal international winger is an unpopular figure in England for his part in Wayne Rooney's sending off in this summer's World Cup.

Ronaldo played his first Premiership game away from Old Trafford on Wednesday in United's 3-0 success over Charlton.

The 21-year-old was one of Sir Alex Ferguson's star performers at The Valley despite his every touch of the ball incurring the wrath of the home support.

Ronaldo believes he handled the additional pressure well and does not believe being an unpopular figure on away trips will be a problem throughout the campaign.

"I know I'm going to get whistled at in every game I play but I am calm about it," explained Ronaldo to the Sun.

"I have been through one away game now in The Premiership and I had to concentrate hard on the match.

"Of course I heard it all, I'm not deaf. I just blocked my ears and concentrated on the game."
