Jeonbuk's True Core (1)
Analyst and coach Yu Tae-ho had a point that was crystal clear this time.
"I'll say it again — Jeonbuk's core isn't some other player. It's Yoon Seung-hwan. Just look back at the early-season matches and you'll see it right away."
It wasn't simply because he scored a lot of goals that they considered him the core. Starting with the ACL match against Suwon Oseong and running through League Rounds 1 through 3 against Ulsan, Gwangju, and Daegu, the finishing touch on every attack had belonged to Yoon Seung-hwan.
"This is analysis data on which player finishes Jeonbuk's attacking sequences. As most of you analysts and coaches already know, the majority of the starting points belong to Baek Yi-an. But when it comes to completing the attack, outside of Park Yeon-woo, Shaperi, and the occasional long-range strike from Kim Choon-jae or Baek Yi-an himself, it's almost entirely Yoon Seung-hwan's job."
Finishing attacks. Given that Jeonbuk had assigned Yoon Seung-hwan the role of poacher, one might think that was only natural. A poacher was, after all, a hunter who lived solely for goals. But Yoon Seung-hwan's real value lay in his conversion rate on shots taken inside the box.
"Heading success rate of ninety-seven percent. And when he shoots, he hammers it at the near post and far post alike — the kind of striker keepers hate facing most. What's even scarier is that he doesn't just wait for the ball to come to him. His off-the-ball movement is remarkably light, and his dribbling in tight spaces is strong enough that he can, if needed, just blast through everything on his own."
A ninety-seven percent heading success rate, and his shooting wasn't far behind. From an analyst's perspective, the stats were so absurd you almost wanted to ask what kind of monster this was. What Yu Tae-ho had discovered while reviewing Yoon Seung-hwan's matches was that the passes aimed at him weren't particularly good.
The accuracy was solid enough. But looking at them, the power control just wasn't there.
Passes that looked more like shots in disguise — even a striker who lived and breathed goals would struggle to cleanly control them or put them away with a header. That a powerful pass invited a poor first touch was something even amateur weekend players knew. So how was Yoon Seung-hwan putting those away?
Obsession. Pure animal instinct for the goal — he's forcing them in with sheer will!
A player who could rightly be called a complete striker. That was Yu Tae-ho's assessment of Yoon Seung-hwan, and of course he was desperate to find a way to counter him.
"Against Jeonbuk, I believe we should stick with the defend-first, counter-second system we've been using. The one difference is that in defensive phases, our volantes will step into wing-back roles and form a pseudo back five — shifting into a 5-3-2 shape."
"A 5-3-2? What's the reasoning?"
"First, we want to exploit the structural advantages of the 5-3-2."
"Structural advantages?"
At the manager's question, Analyst Yu Tae-ho nodded and continued.
"Jeonbuk's main midfielder, Andres, suffered a serious injury against Gwangju, and they've been filling that gap with Kim Choon-jae. It's been working reasonably well so far, but Kim Choon-jae tends to fall apart under intense pressure."
One might think that struggling under heavy pressure was only natural. But in Yu Tae-ho's view, Kim Choon-jae's case was extreme. Looking at just last season's 2028 data, the moment two or more players pressed him, his pass completion rate — which sat at eighty-five percent — dropped all the way to sixty-eight percent.
"In a 5-3-2, the first and second lines are staggered. The space between them is exactly where Kim Choon-jae operates. That means during Jeonbuk's build-up, we can deny him space and force him into isolation, surrounded by our players."
"It's true Kim Choon-jae's decision-making gets cloudy under heavy pressure. When he partners with Baek Yi-an as a double volante, his partner shares the load and he manages fine. But isolated on his own, his weaknesses get magnified. We can also cut the passing lane from Kim Choon-jae to Yoon Seung-hwan without much extra effort."
Yu Tae-ho's expression eased at the coach's agreement — and that was when Manager Nam Jae-yoon immediately pounced on the gap.
"If you're going to talk about structural advantages, you have to talk about the disadvantages too. The 5-3-2 doesn't give space between the first and second lines, sure — but that means three players in the second line have to cover the entire width of the pitch, don't they? Against a team like Jeonbuk that uses the full width of the field, that could be pretty dangerous."
Three players covering the full left-to-right width. That was harder than it sounded. Say, for example, Jeonbuk's winger carries the ball up, lays it off to the fullback, and cuts into the half-space. Naturally one defender has to mark the fullback, and if you want a numerical advantage to win the ball cleanly, you need to send at least one more from the second line. So what then? You're already stretched covering both flanks with three men — and now you're down to two?
Without a solid explanation, this was unacceptable. Manager Nam Jae-yoon looked at Yu Tae-ho with that stance. Of course, Yu Tae-ho had prepared for this part as well.
"On that front, I want to manage the intervals a little differently than usual."
"Differently than usual? You're not just going to say something like 'shift faster,' are you?"
"Of course not. What I have in mind is a bit different. Let me take the scenario you pointed out one step further and assume Jeonbuk has already broken into the half-space. If the half-space has been compromised, that means Jeonbuk players are already infiltrating between our center-backs."
Assuming one side has been breached, the winger and fullback — or a midfielder — will have two players or so positioned between the center-backs. The moment one of them receives the ball and stretches the gaps, the other slips out from between the defenders, takes the pass, and uses the two-on-one numerical advantage to break through. That was the standard way of cracking a compact defensive line. But Yu Tae-ho had a method to stop it.
"We'll stretch the gap between the first and second lines. More precisely, we'll tighten the gap between the second and third lines, and as you mentioned, shift the third line quickly enough to seal any gaps shut."
By compressing the second and third lines, even if a numerical advantage appears, there would be no gap to exploit. Widening the gap between the first and second lines would make counterattacks after winning the ball harder — but at least it would prevent giving up goals.
"Hmm... so you're saying we trade away the attack for a defense packed so tight it makes you want to throw up."
"It's not that we're completely abandoning the attack. Our two strikers are excellent at receiving with their backs to goal. If one player holds the ball up and the other comes to support, they should at least be able to buy us time."
"In other words, we have to run like dogs?"
"Well, I'm not thrilled to say this as someone who works for Seoul United — but this season, Jeonbuk is playing the best football in the K-League. We owe them that much respect. Of course, that doesn't mean we're planning to hand them an easy win."
"So the price of respecting the strongest team is our stamina? I saw that coming a long time ago. I never thought this would be easy."
If running like dogs was what it took to stop them, Manager Nam Jae-yoon was more than willing to pay that price. His football philosophy had always been about not losing, after all. Nodding repeatedly, Nam Jae-yoon carefully reviewed the materials Yu Tae-ho had explained.
Starting from a 4-4-2 system and pushing the volantes into wing-back roles to form a 5-3-2 — the reasoning was solid. What remained was how to counter Jeonbuk's signature tactic: the asymmetric overload isolation...
"All right, let's move on to how we deal with Jeonbuk's tactics."
"Yes. I've prepared for that as well. I've distilled it down to three key points. First: we need to recognize that Baek Yi-an is the core of Jeonbuk's midfield — but we must not rush in trying to shut him down."
"...Go on."
"Yes. Reviewing matches against Jeonbuk, what I found is that as time goes on, teams get thoroughly dismantled in midfield and eventually resort to lottery-style long balls from the back. The root cause, in my view, is forcing midfielders into aggressive man-marking."
"Looking at other teams, that does seem to be the pattern. Suwon got crushed doing exactly that."
"Exactly as you said, Manager. So what we need to keep in mind is simple. Jeonbuk's midfield is extremely good at using third-man combinations, and among them, Baek Yi-an is a player whose ability to escape pressure and control tempo ranks among the very best in the league."
"Acknowledge the opponent and don't charge in blindly. I was already thinking along those lines. Rather than matching fire with fire in midfield, I was considering a more zonal press — one that doesn't give them build-up space or the setup for third-man passes."
Manager Sun Ki-baek, heavily influenced by positional play, treated build-up as his number-one priority. On top of that, he had Baek Yi-an in his hands — a player who was not just top of the K-League, but someone who wouldn't look out of place in Europe right now. So waiting for the right moment through pass-lane control and zonal defending, then winning the ball, was the far better approach.
"But that doesn't mean we can just leave Baek Yi-an alone."
"Leave him alone? That seems a little contradictory to what you just said."
"I can see how it might. What I mean is — we can't leave Baek Yi-an alone."
No matter how he looked at it, Baek Yi-an was the spine of Jeonbuk's build-up. Leaving him free was unthinkable. Of course he had to be stopped. But Yu Tae-ho's idea was that they only needed to stop Baek Yi-an specifically.
"I agree with setting up a primarily zonal structure. What I'm saying is that the moment Baek Yi-an receives the ball, we have to deal with him somehow — even if it means committing two or three men."
Rather than pressing everyone while charging at Baek Yi-an, they would focus their attention on him alone. Of course that would free up players like Kang Sang-yong from pressure — but Yu Tae-ho didn't consider that a serious problem. If someone else received the ball, there were ways to deal with it. But if Baek Yi-an got on the ball, Seoul would find themselves unable to circulate possession even in their own half — a total disaster. It was a choice born of necessity. You could call it cheap. You could wonder if this was really the only solution.
"Hmm..."
"It's true that once the ball finds Baek Yi-an, Jeonbuk's attack suddenly starts flowing."
"..."
But no one could argue against it. They all knew that without committing two or three players to one man out of sheer desperation, victory simply couldn't be guaranteed.
"We've still got time, so if we can refine that point through more discussion, let's do it. Last thing, then — we need an answer for the overload isolation."
"That actually connects to the last point I just made. May I explain?"
When Nam Jae-yoon nodded, Yu Tae-ho worked the remote and played a video. It was a simulation built from data, showing how Jeonbuk's overload isolation tactic moved.
"This is Jeonbuk's asymmetric overload isolation. Normally you'd counter something like this with a balanced system like a 4-4-2, or by reinforcing the wide defense — but as I mentioned earlier, solving this situation also comes back to targeting Baek Yi-an."
"Targeting Baek Yi-an — you mean the transition from overload to isolation?"
"Yes. When Jeonbuk runs this system, the key is drawing the opposition's defensive line toward the overloaded zone, then breaking through on the opposite side with pace merchants like Han Gyeong-rok and Park Yeon-woo. But the common thread I found watching the matches is that on the switch of play, Baek Yi-an is almost always the one delivering the pass."
"Making an accurate switch of play under pressure isn't easy, so that makes sense."
"Exactly. In fact, when Baek Yi-an was suspended for yellow-card accumulation against Daejeon, Jeonbuk used the same tactic — but once Kang Sang-yong took over the switch after the overload, the passes were often inaccurate and the process was nowhere near as clean."
There simply weren't many players who could freely use half-turns and land successful long passes under incoming pressure. Yu Tae-ho was certain Sun Ki-baek would assign that role to Baek Yi-an again this time. So in overload situations, they would apply heavy pressure only on Baek Yi-an, while everyone else prioritized zonal defending and refused to surrender space even after the overload had formed. Simply put: even if it meant getting pushed all the way back from midfield to their own box, they would maintain shape and compress the intervals to the absolute limit. That was Yu Tae-ho's solution to the overload tactic.
"That's all. Based on my analysis, if we execute this role, we should be able to shut down Yoon Seung-hwan — the core of Jeonbuk's attack — while also applying a meaningful degree of pressure on Baek Yi-an."
With a brief bow, Yu Tae-ho ended his briefing. Even as he returned to his seat, silence hung over the analysis room. It wasn't because his materials were shoddy. It was because everyone was already thinking about how, in the remaining time, they could use those materials to actually stop Jeonbuk. And Manager Nam Jae-yoon was no different.
There's no question Jeonbuk is the strongest team in the K-League right now. And at the heart of that are two rising stars — Yoon Seung-hwan and Baek Yi-an.
At first it had felt hopeless. Why weren't players like that at his club? The news was always blaring about population concentration in Seoul, and the front office kept saying their youth pool had grown to rival Pohang's. So why were monsters of this de-K-League caliber coming out of goddamn Jeonbuk? He'd even nearly exploded in rage when he learned that Baek Yi-an had lived in Seoul as a child, and that the coach at the after-school football academy he'd attended was a former Seoul United player and coach.
A love-hate relationship, maybe. As someone who loved football, he was grateful to the heavens that such incredible players had emerged in Korea. As a manager in the same league who had to face them, he cursed the sky. But this time, he decided to set those feelings aside. Respect the enemy — but the moment you revere them, Seoul could die and come back and still never beat Jeonbuk.
The materials Analyst Yu Tae-ho prepared definitely show potential.
In the remaining time, polish them however they could. Work the players hard to raise tactical familiarity. And on match day, even if it meant making them run like dogs, they would take down Jeonbuk.
I might just sink this giant called Jeonbuk with my own hands.
Maybe not any other time — but at least this once, Manager Nam Jae-yoon had conviction.
