If I return to Spain someday, Atletico Madrid would be one of my top choices without doubt. It is a club that I have a lot of affection for.
Rafael Benitez is the best coach I have had. I don't know if I'd have joined Napoli without him being there.
I want to aspire to titles. Liverpool will always be a big club, but we are not at the level of Manchester United, Manchester City, Chelsea, or Arsenal.
I thought I had joined one of the best clubs in the world, one of the biggest names around, and I had, though within a few years, it became clear that I had arrived at one of the worst moments in Liverpool's whole history.
For sure, I would like to continue my life with the strings of football by being a coach, manager - I don't know. But one thing is clear: I will continue doing something related to football.
It is much easier to get over your mistakes when you know you have the confidence of your manager and your team-mates.
The buying power of clubs is very different. You can't sign players if you don't have money, and if there is no money, that's it. As a player, there's nothing you can do.
A club like Liverpool has to be involved in Europe, whether it is the Europa League or Champions League.
My time in England is where I have felt truly like a footballer, and I have put my name among the best players. I'm very proud to have played almost 400 games with Liverpool.
Logically, if there was a chance to improve and go to a bigger club, it would be a good opportunity, although there are few clubs bigger than Liverpool.
This is the nature of football - when you are loved by a team, you really feel it, but when you go through bad moments, you are treated differently.
