Every season is a new challenge to me, and I always set out to improve in terms of games, goals, assists.

I don't understand referees. It appears like some players can't even be touched, but in my case, everyone can hit me as hard as they can.

Ronaldo can do whatever he wants as a footballer. There are some things he does with the ball that make me touch my head and wonder how he did it.

There is no harm in dreaming of becoming the world's best player. It is all about trying to be the best. I will keep working hard to achieve it but it is within my capabilities.

Sir Alex has a special place in my life. In fact, he was the main man. I was not famous, I was not a star. I arrived at Old Trafford as just another young talent. He was the one who told me to do all the right things. He gave me the opportunity to play in one of the biggest clubs in the world. So he is one of the most important people in the world for me. I worked with Sir Alex for a few years and I know he deserves ­everything that he has achieved in his career. He works so hard, he is clever, he has experience, he is a human guy.

Tuesday will be a tough night for me. It's like to return to the family who have not seen you for a long time. I spent a wonderful time there.
