The likes of Wayne Rooney, Dimitar Berbatov, Michael Owen, and Ryan Giggs - I can see it live every day. I don't have to sit in front of a TV to study it.

When I go home, it is quite difficult. Being at Manchester United means it is a huge thing, and when I walk down the street, most people recognize me.

When I am in Korea, I can't walk down the streets. But I don't want to be famous or popular; I just want to be a good player.

By training with some of the world's finest footballers and manager, I feel I have matured in all areas - mentally, physically, and technically.

Manchester United is the world's best club. There is no reason to move to any other team.

When we had a good relationship between North Korea and South Korea, we always connected with sports.

There aren't many Asian players in Europe or the Premier League, so that's more attention for me.

They are always open to come to South Korea and play, because we never reject North Korean athletes.

The happiest moment was when I just played with a ball as a boy, carefree, without worrying about anything.

If it is possible I want to finish my career at Manchester United.

We always try to keep going and stay concentrated. Early goals help that a lot.

Asian fans chase me and shout; it is different in England.

When I'm back in my country, it's like being David Beckham. But it's like that for David Beckham all over the world. It must be more difficult for him than for me.

I just want to be good at soccer and have a normal life; it is a little ironic that you can't have both.

It was funny because on the day that I joined the club, the newspaper that broke the news was one that people don't always trust or believe. Then, when I signed, and there were pictures of me and Sir Alex Ferguson, people believed it.

I've had fans coming up to me and speaking Chinese or Japanese. It's not a case of mistaken nationality. I just don't think they realise that we don't all speak the same language.

We have a long history with Japan. When South Korea play against Japan, the fans tell us that if we lose, they are going to throw the players into the sea.

I thought the sports law sector would be boring, but it was unexpectedly interesting.

There is still a big gap between South America and Europe and Asia, and if we had more players playing in Europe, the gap would be smaller.

I watched Hiddink and Ferguson at close quarters, and I realized that I am not a coach.

Europe is leading the world in the sport of football. I want to utilize my experience from Europe to support the development of football in Asian countries.

I have to stop rushing things. I have to be composed in my mind and slow things down. I think that will make me a better finisher.

At Old Trafford, we are not afraid of anyone.

Against Japan and any Asian teams, we've had good results, so I would say that history proves we are the best Asian team.
