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.

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.

I swear on my children's lives that I never look at the statistics or look at beating anyone's records. All I do is look to improve but not compete against any record. I want to win trophies and score goals because that's my job as a forward.

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.

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.

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.

I worry when I can’t help the team with everything I have to offer.

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

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.

There is always a chance to get even and I'm proud of the fact that for all the blows I always got back up again. That's what makes me most content.

My desire at Liverpool was to help get the club playing in the elite because they had been five years without it. We used to talk about it in the dressing room. If Liverpool are not in the Champions League, it is difficult to get the best players to come to the club.

It's a huge honour to wear No 7 at Liverpool. I think about the legends: Dalglish, Keegan and that Australian guy.
