I was captain in Atletico at 19, playing in the same team as Demetrio Albertini, who won three Champions Leagues, and Sergi Barjuan from Barcelona, who had won everything, and they were 32, 33. I was a kid as captain, so I wasn't the real captain, just a kid learning from them.

One of the reasons I chose to come to Liverpool was because of the mentality of the club. It's a working club and a working city. I don't know why but I feel like one of the people here. They recognise me and wish me luck but in Spain they surround you and you can't do anything. I think they're happy with me here.

Liverpool is a fundamental part of my life. They don't remember me that way, but time will change that. I could not have chosen a better place to go when I left Atletico.

Madrid is not as big as London, but it is true when you are coming from a big city like Madrid, nothing is going to surprise you, and I am very happy to move to a city like London. It is a big city, and you can do everything you want with the respect that the English people always have.

When you become an adult you just make that transition and you're right... it's fun and exciting to be an adult and exciting to have independence, but once you're out from under the cover of your family's protection and love, you sort of have to take a step back and come to terms with the fact that you won't really ever have that again in the same way. You'll never be a kid again.

Fitness is important, but the most important thing is how you adapt and the way you feel physically. To adapt to a new position. To try to change your game.

You have to know what club you are playing for, or you just play for yourself. Every time I put on a Liverpool shirt, I know it is more than just a football game.
