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.

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.

The Premier League is very difficult football and very different to when you play in Europe, but the player has to have experience to adapt, and this is the key point.

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.

I don't know what to say about myself. I don't know myself (laughs). People say my humility but I believe we're all humble in our own way. I try to stay close to my family and friends.

I guess just personally I've become a bolder person in my day-to-day. I think a lot of it came from moving to Brooklyn. I just sort of became an adult and started speaking up for myself and not apologising for myself.
