Kyohei Yoshino and Shin Tae-yong's Wing-Back Gamble at Persija Jakarta

At 31, after more than a decade grinding through J1 League and K League 1, Kyohei Yoshino played wing-back for the first time in his professional career. This was not an emergency cameo for an injured teammate, nor a casual run-out. It was a starting position on both flanks for Persija Jakarta, in the BRI Super League 2026/27, under head coach Shin Tae-yong.

I watched those three matches over two evenings, beside a warm cup of tea and a notebook with a worn spine. When grey hair talks about football, do not rush to cover your ears — the fire is still red. But this time, what made me pause was not a beautiful passage of play. It was a tactical decision packaged inside a few short news lines: a Japanese veteran, who had never played wing-back in his entire career, suddenly placed in the most physically demanding role on the pitch.

In modern football, converting a centre-back or a defensive midfielder into a wing-back is routine. Coaches do it every week, every season, to the point where spectators no longer blink. But one detail makes this story different: Yoshino had never played wing-back at any stage of his career. At 31, he was placed in an entirely new position, with physical and spatial demands he had never experienced. That is the distance between ordinary adaptation and a calculated gamble.

The real point is not that Persija have found a new wing-back. It is that Shin Tae-yong appears to be testing a build-up mechanism from both flanks — where a 31-year-old must simultaneously defend wide spaces and act as a launch point through long passing.

Context: A perfect start and a double-edged sword

Persija Jakarta entered the BRI Super League 2026/27 as one of the leading title contenders. That status has long been established in Indonesian football, where Persija sit among the traditional powers, where the stadium is routinely packed, and where the pressure to deliver never cools. This season, the club has been described as enjoying a perfect start — a phrase Southeast Asian media still deploy rather freely.

But in Southeast Asian football, the word "perfect" is always a double-edged sword. It opens the door to confidence and, at the same time, to complacency. Persija's own internal messaging seems aware of this, because immediately after the positive early results, a warning against complacency emerged from within. A reminder like that, spoken from inside the house while winning, is a signal worth noting.

Against that backdrop, the Yoshino story arrived. He joined Persija with a deep résumé from Japanese and Korean football, having represented clubs such as Cerezo Osaka, Yokohama FC and Tokyo Verdy. At 31, no one expects to resell him for profit, nor to build a long-term identity around him. The expectation is stability, game reading and discipline — qualities that a player forged in two of Asia's leading leagues tends to carry.

What nobody anticipated was that Persija would use him differently. After a substitute appearance against Borneo FC, Yoshino started the next two matches, against Persib and Java United FC. Three matches, and within them, he appeared as a wing-back — sometimes on the left, sometimes on the right. That is a sign that Shin Tae-yong is actively seeking flexibility, both within matches and between them.

A wing-back does more than run

People often talk about wing-backs as if the job belongs to someone whose legs never tire. True, but incomplete. A wing-back in a back-three, or in a flexible back-four, must do several things at once: advance to create width, drop deep to seal the flank, cover the centre-back when opponents attack the channel, and sometimes initiate the first attacking phase from his own half.

Yoshino has said he wants to use long passes. That detail is small but far from minor. It suggests Persija may be using wing-backs not only to overlap in the traditional sense, but also to switch play and start attacks. In a league where many teams still defend with deep, crowded blocks and tight central marking, an accurate long pass from the flank into space behind the opposition defence can break a game open in ways that short combinations cannot.

I have seen this kind of conversion many times in my career. In 2026, while sitting in Guangzhou, I said on my podcast that my hometown club needed to remove seven players over 30 from the starting line-up after a 0-3 defeat to Shanghai Shenxin at Tianhe Stadium. I was called a traitor that day, but I brought numbers: the team ran 12km less than the opponent, and misplaced 45 passes. Those numbers did not explain everything, but they pointed to something the eye misses — that a collective can look glossy while its internal structure has already cracked.

Today, the Persija story offers a curious contrast. Instead of removing an older player, the club has handed a 31-year-old a role that demands more physically than his previous one. That is a paradox only coaches who genuinely trust game intelligence dare pursue.

Historical anchor and the Croatia lesson

Nobody believed Croatia that year, except me and a few drinking buddies. That is what I still say whenever someone asks about the 2026 World Cup, when I sat in a Guangzhou beer bar and declared Croatia would reach the final. Two hundred comments called me a delusional old man. Then Luka Modrić and his teammates beat England 2-1 in the semi-final, and that episode reached 1.2 million listens.

The lesson I drew was not "I was right." It was that teams ignored by the crowd often carry a more resilient structure than their surface suggests. I spent three days recording fan reactions across 12 beer bars in Guangzhou and found that people backed Croatia for a very simple reason — a small team with a big heart. Mainstream media overlooked that detail. Yet it was precisely what kept people sitting together until the final whistle.

In Persija, I see a different version of that story. This is not a small club. This is a giant. But the way they manoeuvre with limited resources in foreign recruitment echoes something very Croatian: when you cannot buy a star, you buy intelligence. And intelligence in football usually comes from players who have crossed multiple leagues, absorbed multiple opponent types, and are old enough not to panic under a press.

Yoshino belongs to that category. Experience in J1 League and K League 1 gives him game reading, duel strength and discipline — assets a younger player cannot yet offer. But that same age of 31 raises questions about sustaining high intensity on the flank across a long season. That is the core contradiction Persija must manage.

The sceptical angle: three matches are not a story yet

Young people look at transfermarkt; I look at a player's eyes when he walks onto the pitch. But this time, I have to admit that neither the eyes nor the data sheet is enough to conclude.

Three matches is a very small sample. Within them, Persija faced Borneo FC, Persib and Java United FC — opponents of differing quality. There is no expected goals data, no possession figure, no pass completion rate, no progressive pass count. Nothing to measure whether this conversion is truly working, or merely being masked by a favourable run of results.

Yoshino himself admits there are still many challenges ahead. A player who says that after three matches is usually someone who understands better than anyone that the new role is not yet conquered.

The most debatable point, and the one I want to question most, lies in squad structure. If Yoshino occupies a foreign or ASEAN registration slot, then his ability to play both left and right wing-back delivers a very concrete benefit: it saves a registration place. One player covering two positions is a bargain in any restricted-quota system. That logic may well be correct — and if so, this deal is not an inspired tactical gamble but a calculated move for roster efficiency.

Yet that same possibility carries risk. A 31-year-old asked to run the flank across consecutive matches faces injury and physical decline. When the season enters its congested phase, when clubs play midweek, when opponents begin to study him more closely and target his channel, the story can turn quickly.

And there is another variable: Persija reportedly contributed six players to the Indonesia national team preparing for the FIFA ASEAN Cup 2026, more than any other club. That is a source of pride, but also a burden. International windows always leave marks: players return late, fitness dips, injuries surface, and club rhythm is disrupted. For a squad that relies on the versatility of multi-position players like Yoshino, losing several links at once can shake the whole structure.

What the numbers have not said

I keep a tracking sheet for every story that interests me. This time, the process-data column was almost empty. That forced me back to what my eyes saw and my ears heard, rather than what a spreadsheet wanted to say.

What I saw was a player who moves with intent, who holds his position when his team loses the ball, and who chooses when to advance. Those are signs of experience, not speed. A wing-back who lives on experience plays differently from one who lives on his legs. He compensates for a lack of pace by reading situations early, standing in the right place, and limiting unnecessary sprints. If Yoshino can do that across a full season, 31 is not a death sentence.

But if the opponent is a fast, direct, technically sharp winger, experience is sometimes not enough. Southeast Asian football is full of such players. They are not famous, not expensive, but they make veterans turn their heads repeatedly across 90 minutes.

Fifteen Zoom sessions during the pandemic taught me that football does not need a stadium, only people watching together. And across those fifteen sessions, what I learned most was not about tactics but about how people see a player. Fans often fall in love with a player over one moment, then turn away over one mistake. Media usually runs about two weeks ahead of the truth. So when a story like Yoshino's appears, I always ask: which part is real, and which part is being told to please the crowd?

What to monitor

If Persija keep starting Yoshino at wing-back for several more matches, that signals a deliberate tactical choice rather than a stopgap. If he begins producing long-pass chances or assists, the story shifts from adaptation to creation. If Persija drop points after international windows, pressure will return to both coach and squad.

And if one day Yoshino is pushed back to a central role, that is not failure. It is simply football operating the way it does.

What I am certain of is this: the real value of a versatile player is not how many positions he can fill, but whether his coach has the courage to use him in the position the team needs most, at the moment it needs it most.

Persija are at the beginning of a long journey. A perfect start is a gift, but also a trap. If this club learns to live with expectation without being swallowed by it, then the story of a Japanese veteran at wing-back will be only the first chapter of a longer book.

If not, those three matches will remain exactly that — three matches. Too small a sample to write anything decent about, and too short to remember.

The storm may stop, the ball may roll slower, but we are still here. And Indonesian fans will sit down to watch whether this gamble pays off.
