I lost my balance, making my body unstable and falling on top of my opponent. At that moment I hit my face against the player leaving a small bruise on my cheek and a strong pain in my teeth.

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.

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'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.

Look, there’s no rule in soccer against biting your opponent. There’s not even a rule against eating your opponent. The only rule in soccer is that you can’t use your hands.

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.

I'm not envious of Leo [Messi]or Ney [Neymar]. Why would I be? If there is envy in the dressing room, you know it's only going to affect results.
