Why Does Lee Kang-in Mean So Much to Koreans?

There are many ways to describe Lee Kang-in.

He is a talented footballer, a South Korean international, and a player who has already played for some of Europe’s biggest clubs. Now, at 25, he has begun another chapter of his career with Atlético de Madrid.

But none of these descriptions fully explain why Lee Kang-in means so much to so many Koreans.

Perhaps the better question is not how good Lee Kang-in is, but rather: Why do so many Koreans feel that his story is, in some small way, part of their own?

We Remember the Boy Before We Knew the Star

For many Koreans, Lee Kang-in did not first appear as a professional footballer. We remember him as a child.

We watched a young boy who seemed unusually comfortable with a football at his feet. Long before he played in the biggest stadiums in Europe, many Koreans had already seen his face and heard his name.

That makes his story different.

When a player becomes famous overnight, fans may admire him. But when you have watched someone grow from childhood into an adult, something deeper can happen. You begin to feel that you have witnessed not only a career, but a life.

Lee Kang-in eventually left Korea and continued his football education in Spain. He grew up in a different language and culture, competing for opportunities in one of the world's most demanding football environments.

And we watched.

He was no longer simply a promising Korean child. He was becoming a professional footballer, then a national-team player, then a player at Paris Saint-Germain, and now a player at Atlético Madrid.

From a Korean Boy to a Global Footballer

In July 2026, Atlético Madrid announced the signing of Lee Kang-in from Paris Saint-Germain on a contract running until June 2031.

It is easy to look at a transfer like this simply as another football transaction. But for Koreans who remember the young Lee Kang-in, it feels different.

The boy who once left Korea to pursue football in Spain has now returned to Spain as an established international player.

There is something almost circular about the story.

He left as a child with a dream. He came back as a professional footballer with a place among Europe's elite.

And before beginning his new life in Madrid, he came home once more.

The Meaning of That Night in Seoul

On August 9, 2026, Atlético Madrid played Manchester City in Seoul.

For Atlético, it was a preseason match. For Manchester City, it was another match on an international tour.

But for many Koreans, the meaning was much more personal.

Lee Kang-in was wearing Atlético Madrid's No. 7 shirt in his home country.

The number itself carried significance. It had previously belonged to Antoine Griezmann, one of the most recognizable players in Atlético's history. Yet Lee Kang-in did not try to make the number his entire identity. Before the Manchester City match, he said he was more focused on contributing to the team than on the significance of inheriting the number.

Then he stepped onto the field in Seoul.

He was no longer the child we remembered. He was Atlético Madrid's new No. 7.

And somehow, his first appearance for his new club took place at home.

Atlético themselves described the match as the moment when Kang In Lee made his Atlético debut on home soil.

There was something deeply symbolic about that. He had spent much of his life building a career overseas, yet his first appearance for his new club happened in front of Korean fans.

The Numbers Tell Another Part of the Story

There is also a fascinating way to understand Lee Kang-in's popularity: look at what fans actually bought.

During his time at Paris Saint-Germain, reports showed that Lee Kang-in became extraordinarily popular in shirt sales.

In October 2023, only a few months after joining PSG, Lee was reported to have surpassed Kylian Mbappé in online shirt sales. At physical PSG stores, he ranked second behind Mbappé.

This was remarkable.

Mbappé was one of the biggest stars in world football. Lee Kang-in was a young Korean player who had only recently arrived from Mallorca.

Yet online shoppers were choosing the shirt with LEE KANG-IN on the back more than any other PSG player's shirt.

That tells us something that statistics on goals and assists cannot.

People were not simply watching Lee Kang-in.

They were choosing him.

They were paying to wear his name.

And Then Came Atlético Madrid

His move to Atlético Madrid has created another remarkable commercial response.

When Atlético came to Seoul, the club brought 10,000 shirts for the Korean visit. According to Spanish sports newspaper AS, all 10,000 were sold.

The same report also said Atlético expected Lee Kang-in to sell five times as many shirts as Antoine Griezmann had sold during the previous season.

The second figure needs to be understood carefully. It is a projection, not a confirmed final sales figure.

But the first number is already striking:

10,000 shirts brought to Seoul — and 10,000 sold.

And this happened around the arrival of a Korean player who had just joined the club.

It is difficult to describe that simply as football popularity.

It looks more like an emotional connection.

Why Do People Buy His Shirt?

This is perhaps the most interesting question.

A football shirt is not simply clothing. When someone buys a player's shirt, they are making a small statement.

They are saying:

“This is the player I choose.”

For Korean fans, choosing Lee Kang-in may carry several meanings.

It can mean pride in a Korean player competing at the highest level. It can mean remembering the young boy they watched years ago. It can mean supporting someone who left home at a young age to pursue a dream.

And perhaps it can also mean something much simpler:

“I want him to do well.”

That last feeling may be the most powerful.

We Have Seen Him Grow

There is a difference between admiring a finished superstar and supporting someone whose story is still unfolding.

Lee Kang-in's career is not finished.

He has already experienced remarkable achievements. At PSG, he won major trophies before moving to Atlético Madrid. But he is still developing.

There will be brilliant games. There will be difficult games. There will be praise and criticism. There will be moments when expectations become heavy.

And Koreans will probably continue watching all of it.

Because we have been watching for a long time.

Perhaps That Is Why Criticism and Affection Can Exist Together

There is an interesting contradiction in the way people respond to Lee Kang-in.

The expectations placed on him can sometimes be enormous.

When he plays well, people celebrate. When he struggles, people criticize. When he does not receive enough playing time, people become frustrated.

But beneath all of this is often the same feeling:

We want him to succeed.

That is not necessarily the same as unconditional admiration. It is something closer to caring about someone's journey.

We have seen the beginning.

So we naturally care about what comes next.

A Story Bigger Than Football

Lee Kang-in's journey also represents something larger for a generation of Koreans.

A Korean child left home and entered a completely different football culture. He had to learn, adapt, compete and grow.

Eventually, he stood on the field wearing the shirt of Paris Saint-Germain. Then he moved to Atlético Madrid.

This does not mean every Korean can follow the same path. But his story reminds us that the world is larger than the place where we begin.

A young person can leave familiar surroundings and build something somewhere completely different.

That idea has meaning far beyond football.

And Then He Leaves Seoul Again

Perhaps the most emotional part of this story is what happened after the match in Seoul.

The Atlético team came to Korea. Lee Kang-in wore the new shirt. He played in front of Korean fans. The shirts sold out.

And then he had to leave.

He had to go back to Spain. Back to training. Back to competition. Back to the difficult work of becoming a better footballer.

In a strange way, it feels like the story we have seen before.

A young Lee Kang-in once left Korea for Spain.

Now an adult Lee Kang-in is leaving Korea again — this time as Atlético Madrid's No. 7.

The difference is that we now know what that journey can become.

We Are Not Watching a Finished Story

Perhaps this is why Lee Kang-in means so much to Koreans.

He is not simply a player who happens to be Korean. He is someone whose growth many of us have witnessed.

We remember the child. We remember the young player in Spain. We watched him become a professional. We watched him reach Paris Saint-Germain. We watched his name appear on shirts around the world.

And now we are watching him begin again in Madrid.

That may be the most beautiful part of his story.

It is not finished.

We do not yet know how many goals he will score at Atlético Madrid. We do not know how many trophies he will win. We do not know whether he will become one of the greatest Korean footballers ever.

But perhaps we do not need to know yet.

Because what makes his story meaningful is not only the destination.

It is the journey.

We are watching a person who once left Korea as a child continue to discover how far his talent, determination and courage can take him.

And maybe that is why so many Koreans still care.

We are not watching a finished hero.

We are watching a person still becoming who he is.

And for now, we are simply waiting for the next chapter.
