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.

Asian culture is that people are quite excited about the players.

I just want to be a normal person.

I have enjoyed every minute of my time at United.

I'm looking forward to playing my part in keeping United at the top of the game.

I study the other players in training, particularly the forwards, and I look at how they are scoring goals. What do they do when they finish a chance?

When I was with PSV Eindhoven in Holland, some people still thought Asian players weren't good enough to play in Europe. It's always good to rise to the challenge and prove them wrong. When I first came to United, I had to prove my ability again.

Early goals make us more confident and energetic for the rest of the game.

All I can do is my best.

I wanted to show that Asian players could make it in Europe. But it was far more important for me just to become a better player. That is why I came to Europe from Asia.

I do not think of myself as a standard bearer for Asian players. I just try to work hard for myself.

All the Asian people respect me and watch me. But I don't want people to think of me as an Asian player. I am just a football player.

I am not worried about playing in front of a big crowd.

There are no easy games in the Premier League.

It always feels good to score goals against big teams.

My first goal is the World Cup, and then my second goal is to win the Asian Cup.

Maybe one of my strengths was to bring the energy to the team, and then defensively, I contributed a lot compared to other players, which is quite essential for the big matches; you know, against big clubs, you need to be very cautious with opponents that attack.

I don't know why I performed well against Arsenal, but probably we prepared well, and it could be their football style as well.

Of my own career, I have many happy memories, but perhaps it - the 2010/11 season, where United broke the record for number of title wins - was the best. I was very satisfied with my performance that year.

Marcus Rashford has done really well. He had a great first season, and then people had really high expectations, but he showed his quality on the pitch in the second season.

The manager wants to show his tactics, and if I do them perfectly, he'll pick me.

My priority is what the manager wants me to do.
