At first I didn't think I was going to fit into Barcelona's way of playing. There was a lot of tiki-taka and I was thinking that without a lot of space to play in, I'd find it more difficult. I worried about that.

I know what my strengths are and what theirs are and what the three of us do is play for the good of the team.

I'd have to say I enjoy myself a lot more, really. I don't feel so much responsibility as I did in other teams. It felt sometimes at Ajax and Liverpool that it had to be me. Now, every time I go out on to the pitch, I enjoy myself and laugh. I have gone through too many difficult times in my career and I don't want to keep thinking about them.

I've got a magnificent relationship with Leo (Messi) and Ney (Neymar). They drive the team, with Andres Iniesta as well - what a player. You know if you have a good relationship with them off the pitch it will be that way on the pitch too. They took it as a sign that I had come to help them, not to compete with them.

In Latin America the border between soccer and politics is vague. There is a long list of governments that have fallen or been overthrown after the defeat of the national team.

It was a dream to arrive at Liverpool but I never wanted to just settle for what I had achieved. I wanted more.

Everything you see comes from inside. People don't see it but inside the dressing room we laugh and joke a lot so it's not just for the cameras. It's the way things are off the pitch too. We are happy for each other, it is all natural.
