Cristiano Ronaldo hits back at critics of his work rate at Man Utd

Cristiano Ronaldo has vowed to silence his doubters by leading Manchester United to trophies in the coming years.

The 36-year-old's quality is undeniable, but as he did with Juventus, Ronaldo has faced immense pressure from critics of his work rate off the ball, with some claiming his arrival has actually harmed United as a whole.

Nevertheless, he has continued to score goals - six in his first nine appearances - and Ronaldo insisted anyone who doubts him as a player is simply just jealous of his success.

"I know when the team needs my help defensively," he explained to Sky Sports. "But my role in the club is to win, help the team to win and to score goals - [the defensive side] is part of my job.

"The people who don't want to see that is because they don't like me but to be honest I'm 36, I win everything so am I going to be worried about the people who say bad things about me? I sleep good at night. I go to my bed with my conscience very good. Keep going with that because I will still close mouths and win things.

"Criticism is always part of the business. I'm not worried about that. And I see it as a good thing to be honest. If they worry about me or they speak about me, it's because they know my potential and value in football still. So it's good. I'll give you an example: if you're in a school and you're the best student, you ask the worst student if he likes the best, they'll say they don't like him.

"I think the main word is that I'm still happy and enjoying football. It doesn't matter how many things I won in my career. I win everything but I'm still motivated. I'm in a new chapter of my life, even with my age, and this is why I am here - to try to win and I think Manchester needs to be at this level of winning and thinking to win big things so I'm here to help."

Ronaldo is without a goal in his last three Premier League appearances, in which United have picked up just one point, but he will hope to rectify that on Sunday when Liverpool rock up at Old Trafford.

Goals against Liverpool have not always been easy to come by for Ronaldo. He has three in just 12 appearances across his time with both United and Real Madrid, two of which came in his last two tastes of this fixture at Old Trafford.
