There is a version of a breakout moment that arrives quietly, buried in a stat line nobody checks until days later. And then there is what Lee Kang-in did on September 20, in the biggest club fixture Spanish football has to offer, in front of a full stadium and a global television audience: he started his first-ever Madrid Derby, played 89 minutes at the point of attack, and threaded the pass that led directly to the goal that put Real Madrid away for good. Atletico Madrid won, 2-1, and by the time the final whistle blew, Lee’s fingerprints were all over one of the club’s signature results of the young season.
The victory, Atletico’s third straight in La Liga, did more than settle a local rivalry for bragging rights. It vaulted Atletico Madrid past Real Madrid and into second place in the league table — a jump made possible in no small part by a 24-year-old South Korean midfielder who, not so long ago, was still fighting to establish himself as a regular starter for one of Europe’s most demanding clubs.
A Derby Debut, Finally
For American readers unfamiliar with the geography and politics of Spanish football, the Madrid Derby needs a bit of context to land with its full weight. Atletico Madrid and Real Madrid share a city, and little else. Real Madrid is the sport’s most recognizable global brand, the club of Cristiano Ronaldo’s most decorated years and more European Cup and Champions League titles than any other team in history. Atletico, by contrast, has spent decades building an identity as the scrappy, defensively disciplined counterweight — a club that takes particular pride in beating its glamorous crosstown rival. If there is an American analog, think of a Yankees-Mets rivalry, except with direct Champions League qualification and league-title implications riding on the result every single time the two sides meet.
Lee Kang-in had never started one of these games before September 20. He arrived at Atletico Madrid via a path that included stints in Spain’s lower-tier academies and a rise through Mallorca before he became a full-time fixture in one of the league’s marquee rosters. Entering this particular derby, Lee had strung together seven consecutive league starts — a run that signaled growing trust from his coaching staff — but the derby itself represented a different tier of pressure entirely. Deployed in a 4-4-2 formation alongside striker Jonathan David, Lee lined up at the point of attack rather than in a deeper midfield role, tasked with combining creativity in the final third with the willingness to press and harry Real Madrid’s back line. He would go on to play 89 minutes, substituted only in the closing moments of stoppage time, a workload that in itself said something about how central he had become to his team’s plan for the biggest game on the calendar.
A Red Card, a Penalty, and the Game Turns
The match remained scoreless through a tense opening 45 minutes, with both sides wary of the moment that could decide the outcome of a fixture this tightly contested. That moment arrived early in the second half. Real Madrid defender Dean Huijsen committed a foul inside his own penalty area, and after a video review confirmed the infringement, the referee pointed to the spot and produced a red card, sending Huijsen off and leaving Real Madrid to play out the remainder of the match a man down.
Alejandro Grimaldo stepped up to take the resulting penalty and converted with a composed finish, low into the corner, to give Atletico a 1-0 lead. For a club that has spent the better part of a decade defining itself by its capacity to grind out results against superior individual talent, taking the lead against a ten-man Real Madrid side was the kind of opening the home fans in the Metropolitano stadium had been waiting for.
The Pass That Sealed It
What happened next is the moment that will define Lee Kang-in’s afternoon in the retelling. With Real Madrid down a man and stretched defensively, Lee spotted the space opening up behind the visitors’ back line and slipped a through ball into the gap — the kind of pass that requires both the vision to see the opening before it fully materializes and the technical precision to execute it under pressure, in a stadium at full volume, in a match with the highest possible stakes for both sides.
Giuliano Simeone — the Atletico winger whose father, Diego Simeone, has managed the club for more than a decade and built its entire modern identity — ran onto Lee’s pass on the right flank and delivered a cross into the box. Jonathan David, the striker Lee had spent the whole match linking up with in that 4-4-2 setup, met the cross and finished calmly with his right foot, doubling Atletico’s advantage to 2-0. In the buildup that produced the goal, Lee Kang-in was the first domino — the player whose pass unlocked a defense that had, until that instant, been holding relatively firm despite its numerical disadvantage.
For American readers more familiar with basketball’s vocabulary of playmaking than football’s, the comparison is almost exact: Lee’s pass was the equivalent of a point guard’s assist on the play that puts a game away, the kind of contribution that shows up in the highlight reel as clearly as any finish, even though someone else’s name ends up on the scoresheet as the scorer.
Real Madrid’s Late Push, and a Result That Held
Real Madrid did not fold entirely. Deep into stoppage time, with the match well out of reach on the scoreboard but pride and momentum still in play heading into the following weeks of the season, Bernardo Silva delivered a free kick into the box that Antonio Rudiger met with a header, pulling one goal back and making the final score 2-1. It was a consolation strike rather than a genuine turning point — there was simply too little time left on the clock for Real Madrid to complete a comeback against a ten-man deficit they had been fighting since the first half — but it added a note of tension to the closing minutes and ensured the final scoreline reflected a contest rather than a rout.
When the whistle finally sounded, Atletico Madrid had its derby win, its third consecutive league victory, and a new position in the table: second place, ahead of the very rival it had just defeated. For a club that measures its season in large part by how it fares against Real Madrid and Barcelona, a derby win of this magnitude — earned with a red card working in their favor but converted with real quality in the buildup to the second goal — is the kind of result that can set the tone for months of the season to come.
A Postscript: The Tackle That Drew a Second Look
Not everything about Lee Kang-in’s afternoon was pure celebration. In the aftermath of the match, a hard tackle Lee made on Real Madrid’s Federico Valverde drew scrutiny and debate among pundits and fans over whether it should have resulted in a card of its own. The referee did not issue one in the moment, and no retrospective action followed, but the tackle became a talking point in post-match coverage regardless — a reminder that derby matches of this intensity often carry an undercurrent of physical edge that outlasts the final whistle, even when the officiating itself does not change as a result.
That kind of moment is worth including in the full picture of Lee’s derby debut not because it defines the outcome, but because it reflects the reality of what these matches demand from every player on the pitch. Madrid Derbies are not decided purely on technical quality; they are contested with an intensity that occasionally spills over into exactly the kind of hard challenge that draws a second look from broadcasters and rival fans alike. Lee Kang-in, for his part, emerged from that intensity with his team’s result intact and his own performance — 89 minutes, a derby start, an assist on the goal that sealed the win — firmly the story of the day.
The Simeone Connection, and a Manager’s Long Rivalry With Real Madrid
It is worth pausing on the identity of the player who actually finished the buildup that Lee Kang-in started. Giuliano Simeone is not simply a teammate — he is the son of Diego Simeone, the manager who has overseen Atletico Madrid for more than a decade and, in doing so, built the club’s entire modern identity as Real Madrid’s most stubborn domestic rival. Under the elder Simeone, Atletico has made a habit of finding ways to beat Real Madrid in moments that matter, often through exactly the kind of collective, high-intensity performance the club produced on September 20. That a goal in this particular derby ran through a South Korean playmaker’s pass and a manager’s son’s cross before reaching a Canadian striker’s boot is, in its own way, a small illustration of how thoroughly international the modern Atletico squad has become, even as the club’s competitive DNA against Real Madrid remains unmistakably the same as it has been for years.
Diego Simeone’s Atletico teams have long been built on a reputation for defensive rigor first, with attacking moments manufactured through discipline and opportunism rather than pure individual flair. The buildup to the second goal on September 20 bent that reputation slightly, in a good way for Atletico supporters: it was a passage of play defined by a defense-splitting pass, a well-timed run, an accurate cross, and a clinical finish — the kind of fluid, attacking sequence more often associated with Real Madrid’s own attacking talent than with Atletico’s traditionally more pragmatic approach. Lee Kang-in’s role at the start of that sequence is part of what has made him such a valuable addition to a squad historically light on that specific kind of vision in the final third.
What This Means for Lee Kang-in’s Standing at Atletico
Individual performances in marquee fixtures tend to carry outsized weight in how a player’s role at a club evolves, and Lee Kang-in’s derby debut fits that pattern closely. Seven consecutive starts heading into the biggest match of the season so far was already a signal that Atletico’s coaching staff considered him essential to their plans. Being trusted with a central attacking role in a 4-4-2 alongside the team’s primary striker, in a fixture this significant, took that trust to another level. Delivering the pass that produced the clinching goal, in that context, is the kind of moment that can cement a player’s standing for an entire season — the difference between being a valued squad option and being the player a club builds its biggest matches around.
For South Korean football fans, Lee’s performance carries an additional layer of significance. Korean players have increasingly found regular roles across Europe’s top leagues in recent years, but a Korean player starting — and directly influencing the outcome of — a fixture as historically loaded as the Madrid Derby remains a comparatively rare milestone. It places Lee’s name alongside the short list of Korean footballers who have made a direct, decisive impact in one of the sport’s genuine spectacle matches, rather than simply appearing in the squad for one.
Looking Ahead
Atletico Madrid now sits second in La Liga, three wins deep into a streak that began before this derby and gained considerable momentum because of it. Real Madrid, for its part, will have to regroup after a match complicated by an early red card and a defensive stretch it never fully recovered from, even with the late consolation goal to soften the final margin. For Lee Kang-in, the challenge shifts to consistency: turning a signature derby performance into the new baseline expectation, rather than a peak moment in an otherwise steady season. If September 20 is any indication, Atletico’s coaching staff already believes he is capable of exactly that — and on the evidence of his first Madrid Derby, it is hard to argue with them.
