United are more popular around the world. There is a difference and I can see that. Bayern Munich is a big club but United are bigger. When we [Bayern] were in China people knew us but Bayern were not so big in America.
For me, Real Madrid are just like any other club, like Barcelona, Milan, Bayern Munich, or Inter. Just another big club.
All I can do is assess the value from Manchester United perspective. Whatever Chelsea do, they may have a different criteria, and different financial assets.
I don't like to compare clubs or players from way back. It's different today. Your ballparks are better. In the days when I played, we had eight teams in each league. Now you have more.
Compared to other clubs, what we've achieved under Gerard Houllier is exceptional.
I have huge respect for Porto, a great club that's always in the hunt for titles, but they aren't Real Madrid, one of the biggest clubs in the world.
I've played for Real Madrid and Inter, clubs at the highest level, but Corinthians is a well-organised club and a reference for our country.
There's probably about 150 charters in the world. We're the biggest international club there is.
It is a lot easier to manage at a big club rather than at a smaller one. Look at Frank Rijkaard. At Sparta Rotterdam, he was disastrous - and then went to Barca and won everything.
Where do you go from Real Madrid that's better? There's one or two clubs up there but none better.
Lyon is a big club, but not one of the five best in Europe.
It is tough to find a European club with the kind of infrastructure that Corinthians have.
Tottenham are a big club. They are probably bigger in structure than PSG.
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.
There's no other club where I'll be able to work with better players than at Barca.
Chelsea gave me what I was looking for when I left Liverpool trophies. I'll always see it as a success.
With Arsenal there was an interest but not a big as other clubs. That is why I didn't go to Arsenal and went to Chelsea.
