I'm lucky to be part of a team who help to make me look good, and they deserve as much of the credit for my success as I do for the hard work we have all put in on the training ground.

You cannot allow your desire to be a winner to be diminished by achieving success before and I believe there is room for improvement in every sportsman.

I always thought I wanted to play professionally, and I always knew that to do that I'd have to make a lot of sacrifices. I made sacrifices by leaving Argentina, leaving my family to start a new life. I changed my friends, my people. Everything. But everything I did, I did for football, to achieve my dream.

The day you think there is no improvements to be made is a sad one for any player.

I have many years to get better and better, and that has to be my ambition. The day you think there is no improvements to be made is a sad one for any player.

The truth is my idea has been to always stay at Barcelona and see out the rest of my career here. Like I always say, one doesn't know what can happen in the future, but if it were up to me to decide, I would stay at Barcelona for the rest of my career.

There's nothing more satisfying than seeing a happy and smiling child. I always help in any way I can, even if it's just by signing an autograph. A child's smile is worth more than all the money in the world.

Money is not a motivating factor. Money doesn't thrill me or make me play better because there are benefits to being wealthy. I'm just happy with a ball at my feet. My motivation comes from playing the game I love. If I wasn't paid to be a professional footballer I would willingly play for nothing.

Nah, I've always had a great relationship with my two brothers, I have always had their support in my football and in everything. They've been very close to me and we have a great relationship.

The truth is that I don't have a favourite goal. I remember important goals more than I do favourite goals, like goals in the Champions League where I had the opportunity to have scored in both finals I have played in. Finals in the World Cup or Copa del Rey are the ones that have stayed with me for longer or that I remember more.

You have to fight to reach your dream. You have to sacrifice and work hard for it.

I prefer to win titles with the team ahead of individual awards or scoring more goals than anyone else. I'm more worried about being a good person than being the best football player in the world. When all this is over, what are you left with? When I retire, I hope I am remembered for being a decent guy.
