I'm paying for a mistake I made

I never told you this but I always thought the club should have recognised you far more when you retired. For the career that you had, one of Liverpool's greatest players, you should have had a much bigger and better send-off in your final match. That's just what I felt.

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.

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

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.

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.

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.
