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.

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.

Gabriel Batistuta. He was a spectacular No 9 - great at finding space, shooting from outside the box, good in the air. He was always a reference for me and I used to watch the way he played.

Steven Gerrard is the best player I've ever played with.

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

You just can't believe how quickly things happen in football and the way life turns. I went from being the bad guy, the worst player who gets all the criticism, to being the player who makes the difference and scores the important goals.
