You have to give 100 percent in the Champions League, as you're up against the biggest teams.
I won't lie, I want to play in the Champions League and challenge for titles.
The margin for error in the Champions League is tiny.
If you are in the Premier League or at Barcelona, Real Madrid, or Bayern Munich, you are at an end station.
Of course you have Messi and Ronaldo. And then you've got a lot of players who are very close to each other and I think Gareth Bale is one of them, like at the level of the best teams in the world. He could play for every team in the world. For me he's a world class player.
It's difficult to understand someone leaving Barca, with the best players in the world.
Every player would love to get to the absolute top, and Real Madrid is it.
Who does not want to coach Barcelona?
In football, you never know what can happen tomorrow. This is the elite, and you have to be ready for any situation that can occur.
There are some big teams out there who don't play in Champions League, but I can't deny that I'd love to play in Europe's most prestigious competition.
Obviously, training at Barcelona is a fantastic experience. You train alongside players like Lionel Messi and Andres Iniesta, who are clearly some of the best players in the world.
For me, the Premier League is the best tournament in the world. It's the hardest; you need to be 100 per cent to play every game.
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.
The Premier League is the toughest league in the world, so it's never going to be easy to get minutes.
Manchester United would like to have world class players.
You can play football in Bayern, in Barcelona, in Manchester, in London, wherever. In the end, it's football, and you want to play with the best.
Obviously the Champions League is the top of football, where everyone wants to play.
Real are the best club in the world. Any footballer dreams about playing there, and I am no different.
Only Bayern Munich really have some sort of a guarantee to win if they only catch a good day. All the others need really good days to win. I like that.
When you come to Paris you are at a club that has the ambition to be the best in the world, you have come to a club that wants to play in all the competitions.
You want to play in the best stadiums against the best players - your Real Madrid's and Barcelona's - you want to play those teams.
Who wouldn't want to play for Real Madrid? Like Manchester, they are one of the best clubs in the world - and it would be a pleasure to play for them.
This is what you dream about as a footballer: playing with the best and against the best in Europe.
The Champions League without Milan is not the Champions League.
You wanted me to do what? That I say no a second time to Barcelona? It was impossible for me. I'm in a crazy club there, next to the best. Every year, the club is semi-finalist or finalist of the Champions League!
