There is no question that Korean footballers have the ability to play in Europe. The real challenge is whether they will be able to adapt to western culture.

I don't want fame or to make money by appearing on TV, but I would not mind appearing on TV if it is related to what I am doing for football.

Once I became more famous, I was proud that people in Asia started to look towards me.

North Korea and South Korea speak the same language, and actually, we are the same country.

My reputation has increased, not just in Korea but across the continent.

Lee Chung-yong has been playing well and trying hard at Bolton and has grown in confidence. His improvement is valuable for the national team.

Although the Premier League is tough because players have good physiques and can switch swiftly in offense and defense, it can be overcome after adapting to the league for a few months.

I try to help the team to win, and my role is to run a lot and bring energy to the side. It's my job, so I have to do it.

I don't like to be famous.

To become a good coach, it is important to be equipped with tactics and strategy. But first of all, you need to have strong leadership.

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

At Old Trafford, we are not afraid of anyone.

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.

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

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

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'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.

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

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.

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

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

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

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

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

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

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

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

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

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.

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.

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.

We need more of our players to follow the trend and move to Europe, which is the biggest stage in world football, but we're not doing that, and that makes it difficult for us to compete with other countries.

It would be honour for me to keep playing for Manchester United.

I need to improve my finishing. I need more goals.

Many Asian players have seen they can play in Europe at a high level.

I am very happy that I proved Asian players can deal with the high levels of European football.

A lot of the South Korean players are very interested in the Premier League. They ask questions about what life there is like, so I try to give them answers.

In Korea, if a player makes a mistake, the other players don't like to point it out. Rather, they try to embrace it; they take the attitude, 'Let's do better next time.' But in the West, if you do something wrong, another player will make a point of saying something, and you will have to fix it immediately.

It was a very difficult decision to leave United.

When I made up my mind for Manchester, I felt I had betrayed Hiddink. I knew he wanted me to go to Chelsea, so I found it difficult.

There's no truth at all that I would leave United - I want to stay here, and I have no reason to leave. I would like to stay here for life, of course - why not? It's the best club in the world.

It's unbelievable. I never thought I could play for United 200 times.

I love playing for United and have lots of good memories from my time here.

Some players aren't able to show their ability in Europe, but some players can - I think the most important quality in the successful players is that they are mentally strong.

The biggest thing for Asian players to remember is the football style is different in Europe - as is the culture - so they have to accept that. Mentally, they need to be ready and very strong.

Managers now don't just use 11 players; they have to care about all the squad of 25 or more players.

The best goal I have scored for the national team would be during the 2002 World Cup against Portugal. It was my first World Cup and my first goal in the World Cup. It was like a dream, and that's why it was so memorable.
