Yang Hyun-jun's Match-Winning Performance for Celtic

Yang Hyun-jun left Paisley with the match ball in his grasp and Celtic with three precious points, but the real story was bigger than one clinical swing of his left boot.

On a tight, anxious afternoon at The Marbill Coaches Stadium, with the Scottish Premiership champions pushed hard by St Mirren, the 24-year-old South Korean produced the decisive moment. On 5 September 2026, in the 68th minute, Yang darted in from the left and, after a terrific piece of work from the equally impressive Camilo Duran, drilled his shot home to make it 2-1. Celtic never let that lead go.

The goal was crisp. The significance was sharper.

A parting gift with perfect timing

This was Yang’s farewell – for now. He heads off to join the South Korea squad for the Asian Games, and he could hardly have signed off in more emphatic fashion.

He ran at the Buddies with purpose, twisted defenders inside out and, crucially, delivered where it matters most. This wasn’t just another lively wide-man performance; it was the display of a player who has grown into a key figure in Martin O’Neill’s side and knows it.

His finish in Paisley was his second goal in as many games, backing up his strike against Aberdeen at Celtic Park the previous Wednesday night. Two games, two goals, both in tight domestic contests. That’s not a cameo contribution. That’s a pattern.

Yang looks increasingly at home on the left flank, which suits Celtic nicely. On the opposite side, Haissem Hassan has started to look just as comfortable carrying the ball and stretching defences, even if the final product from the Egyptian international is still to properly click. That will come. The structure is there; the numbers will follow.

For now, though, Yang is the winger with the end product – and Celtic are about to find out what life looks like without it.

A costly absence at a crucial moment

His call-up means he will miss the trip to Perth on Wednesday night to face St Johnstone. That alone is a frustration for O’Neill. The schedule around it turns it into a genuine headache.

Celtic face a Glasgow Derby double header against Rangers in the coming weeks, the type of fixtures where pace, bravery and a goal threat from wide areas can decide the narrative of a season. On top of that, there is the Europa League opener against Hungarian runners-up Ferencvaros at Celtic Park, a match the club will be desperate to win to stamp authority on the group from the first whistle.

Yang’s attributes – the direct running, the tricks on the flank, the sudden acceleration into the box and, now, the goals – would have been central to all of those plans. Instead, O’Neill must reshuffle.

The manager knows exactly what he is losing. So do the supporters. A year ago, the idea of Yang missing a run of games might have been met with a shrug. Now it feels like a genuine blow.

That shift tells its own story.

From nearly sold to almost indispensable

It is hard to think of another recent Celtic player who has transformed his standing so dramatically. Not long ago, Yang was on the verge of leaving. Around this time last year, he was set to be sold to Birmingham City for around £3 million, a deal that only collapsed because of the wider failings of the club’s summer 2025 transfer window.

That messy period, one the support knows all too well, inadvertently handed Yang a second chance. He has not wasted it.

Under the guidance of the veteran Irishman in the dugout, the winger has sharpened his decision-making, toughened his game and added a ruthless streak in the final third. The raw talent is still there, but it is now wrapped in structure and confidence. He looks like a player who understands his role and trusts his own ability to change games.

The difference is stark. Twelve months ago, few would have complained if his name had been missing from the teamsheet. Now, his absence is being measured in terms of how many points and how much European momentum Celtic might have to claw back without him.

If this trajectory continues over the course of the season, the speculation will follow. A player once nearly moved on for £3m now looks capable of commanding a fee in the £25m bracket and beyond. That is not fantasy; it is simply where the market goes for wide players who can beat a man, score, and influence games at European level.

Enjoying the player he has become

In Paisley, the images told the story. Yang wheeling away after his 68th-minute strike, arms spread, the Celtic support behind the goal erupting. Team-mates racing over – Liam Scales among the first to reach him – knowing exactly how important that goal could prove in a title race that rarely forgives dropped points.

He has become a first-team asset in the truest sense. Not a squad option. Not a prospect. A player O’Neill builds game plans around.

Those plans now need a short-term rewrite while Yang chases medals with his country. When he returns, the expectation will only grow. So will the interest from elsewhere if he keeps cutting inside from that left flank and deciding matches.

For Celtic, the equation is simple.

They almost lost him once. They very nearly undervalued him. Now, as he disappears to the Asian Games on the back of another match-winning display, the club and its supporters are left with one clear thought.

Enjoy Yang Hyun-jun while he’s still here.
