Street football is the greatest thing in the world. There is just you and your friends against the rest.

When I first joined Manchester City, I was not 100 per cent fit.

I miss Boca. I miss the fans, wearing the jersey every Sunday, and stepping on to La Bombonera.

I did not transfer from United to City for the controversy.

I want to go back to Manchester and win the City fans back.

I don't like making comparisons. You might say one slight thing, find yourself misinterpreted, and suddenly you're in trouble.

I like Manchester, I love the fans. They are great with me, the club is great with me. But I'm not happy if I don't play, and all the time I don't play.

Sometimes in a game - even with the best will in the world - a striker can drift out for 10 minutes and then come back into it.

I don't like to get involved in conflict.

City's boss and owner came with a very good proposal. They showed me that City has the ambition to be one of the biggest clubs in the world. This made it easy to make the move. Money was never important.

I would like to play for a club who I feel have true ambition.

You have to do your talking on the pitch. I don't talk much in England - mainly because of the language.

Messi would never tell a coach who he has to play or not. I think he not only lacks the power to do that but also is not humanly capable of saying that.

Of course I would buy a house in Marbella. In Marbella, you can buy a house by the beach, relax there, and later you can go there on holiday and everything.

My wish is to concentrate on playing football for Manchester City.

The first thing United's fans have to understand is that a part of my heart will always be with them. They were very supportive, and they always made me feel good even when I wasn't playing, so I will always keep that in my heart. The second point is that the reason I did not stay at United was nothing to do with the fans.

I don't regret anything, not even leaving Boca because it was the time to do so.

I am a striker, a goalscorer. That is my art.

Everything I do, I do for my daughters.

There are three sportsmen: Tiger Woods, Roger Federer, and Lionel Messi. They perform with excellence, like most of us could never dream of.

Every single thing related to Old Trafford is amazing. When I was a little kid, I dreamed of playing in a real field, but I never imagined something as fantastic as this.

Lionel Messi, I never saw him in the gym. I've never seen him train in the stops or do technical exercises.

I was, in my first season, second top scorer, which is something people forget.

Of course you can never say zero possibility or 100 per cent possibility in football, because you never know what will happen because football changes so rapidly.

I love the English league. I think it's the best in the world, but I have a problem with Christmas and New Year's Day because you have to play.

In Argentina, I trained in the mornings, and I played a lot of golf.

After spending eight years in Manchester, I received a very warm welcome to Turin. The people are very easy-going, in contrast to other parts of Italy such as Rome or Naples, where passions run much higher.

When you have to play football, you do it in the knowledge that there's a lot riding on the match, be it money, your team-mates, or the feelings of the fans.

You simply can't get inside the heads of other people and say to them, 'Look, I went through some rough times.' It's impossible to explain everything the streets taught me, and that was quite a lot.

Experiencing difficult things, even as a very young kid, means you grow up quickly. I think that enables everyone to choose their own path and not just accept the one others have taken before you, and I went my own way.

It did surprise me to be made captain. The obvious issue is my English. It's not that great, so communicating with players is not always easy. But I am thriving on the responsibility, both on and off the field.
