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.
It's not easy to come somewhere new and have to find your place. You might feel someone doesn't like you, or you might need to find new friends. It's not easy, and I don't like this kind of thing. It's not easy, so you want to protect the players who are alone.
I didn't realise how my life was changing. When I was 17, 18, 20, I didn't realise how big football was and everything around football. How many people live for football and love football. I was a professional, but I was a supporter.
I remember when I first came to Liverpool, Pepe Reina helped with everything, and he made it easy for me. When I was Atletico Madrid captain, I tried to help everyone. These are the basics in football: you need to create an atmosphere and try to create a group of friends. It's not easy, and it doesn't always happen, but you have to try.
The biggest ambition in my career is still to win the European Cup. I want to have a picture of that to look at later; I want to have that medal. You can have a contract that is better than your friends, but no player looks back and says: 'I won more money.'
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.
I am a big fan of the Gallagher brothers. At Liverpool, they came a few times; they are friends of Steven Gerrard. It was nice to meet them. When I was in Spain, I couldn't speak English, so I couldn't understand the lyrics. When I came to England, I started studying music and trying to understand what my favourite songs said.
Liverpool is a massive club in reputation, but as soon as I came here, it felt like Atletico to me. It is a working city, an honest city. The people work all week, and on Saturday they want to go to Anfield and watch the best team in the world.
The writing is therapeutic for me, it's an introverted process, I'm really inside my head. It's a really obsessive process. The live show, though, is the opposite. It's an extroverted process. It pushes me to connect with people, and so it pulls me out of my head and just pulls me out of myself.
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.
