In a dramatic semi‑final showdown at Hampden Park, Celtic secured their place in the Scottish Cup final after a hard‑fought 6‑2 victory over League Cup champions St Mirren, a match that stretched into extra time before the Glasgow giants finally asserted their dominance. The fixture was especially poignant because Celtic’s manager, Martin O’Neill, will now meet his former captain, Neil Lennon, who is guiding Dunfermline Athletic into the final after their own penalty‑shootout triumph over Falkirk.

The opening stages of the game belonged to St Mirren, who grabbed an early lead within the first minute. Backup goalkeeper Ryan Mullen, thrust into the starting XI because of an injury to Shamal George, mishandled a low ball from Japanese forward Daizen Maeda. Maeda pounced on the mistake, sliding the ball into the net to put the visitors ahead.

The goal was a harsh reminder of how quickly a match can turn when a momentary lapse occurs at the back. Mullen’s misfortune compounded when, just fourteen minutes later, he suffered an injury of his own. The young 17‑year‑old Grant Tamosevicius was summoned from the bench to make his senior debut. Despite the pressure of the occasion, Tamosevicius displayed composure, making a smart save from Maeda and handling the ball confidently with his feet before eventually being beaten by Anthony Ralston as the half‑hour mark approached.

Ralston’s strike struck the post, and his follow‑up effort hit the bar, underscoring Celtic’s growing threat. Celtic’s early dominance was further highlighted by a superb defensive effort from Finnish centre‑back Viljami Sinisalo, who made a crucial clearance to deny Liam Donnelly’s powerful header from a corner. However, Sinisalo nearly mirrored Mullen’s error when Mikael Mandron dispossessed him inside his own six‑yard box.

The resulting chance was squandered by Killian Phillips, whose close‑range attempt went wide, allowing Celtic to escape what could have been an early equaliser for the visitors. The first half ended 2‑0 in St Mirren’s favour, with Maeda’s opener followed by a second goal from Anthony Ralston, who capitalised on a clever back‑heel from teammate Yang. The Scottish side entered the break with confidence, having taken the lead twice in rapid succession.

The second half began with St Mirren appearing comfortable, but Celtic’s resolve did not waver. Eight minutes after the restart, Mikael Mandron, the French striker who had previously helped his team win the League Cup earlier in the season, found the back of the net.

He rose to meet a chipped cross from Declan John, heading the ball past the on‑looking goalkeeper to make it 2‑1. This goal marked Mandron’s first for St Mirren since December and sparked a shift in momentum. Celtic responded quickly, creating several chances, but St Mirren’s defence held firm for much of the period. In the 87th minute, Sinisalo produced a double‑save that momentarily kept the scoreline intact.

Yet, in stoppage time, Mandron seized his second opportunity of the evening. He timed a well‑placed through ball perfectly, sprinting past the defensive line and unleashing a powerful strike into the far corner, forcing the game into extra time at 2‑2. The extra‑time period saw Celtic unleash their attacking pedigree.

Within six minutes, substitute Kelechi Iheanacho headed home from a James Forrest cross, restoring Celtic’s lead. Two minutes later, Luke McCowan calmly slotted a low finish, extending the advantage to 4‑2. Iheanacho then demonstrated his striking prowess again, curling a shot into the top corner at the 100th minute for his second goal of the match. Finally, Benjamin Nygren capped the scoring spree with a well‑taken finish, sealing a 6‑4 aggregate victory for Celtic.

The win not only propelled Celtic into the Scottish Cup final but also set up a compelling narrative for the climax of the competition. They will face Dunfermline Athletic, who earned their place by defeating bitter rivals Falkirk in a tense penalty shoot‑out. The upcoming final, scheduled for May 23 at Hampden Park, will be a reunion of two footballing icons: Martin O’Neill, who guided Celtic to numerous trophies, and Neil Lennon, his former player and long‑time colleague. Lennon, now managing Dunfermline, expressed his excitement about the prospect of facing O’Neill.

He described the encounter as “a privilege and an honour,” recalling their shared history at both Leicester City and Celtic. He reflected on the personal bond they have cultivated over three decades, noting that their first meeting dates back to 1996 when O’Neill signed him for Leicester. Lennon’s comments highlighted the respect and admiration that still exists between the two, despite the competitive stakes. O’Neill, for his part, welcomed the chance to test himself against his former protégé.

He praised Lennon's achievements at Dunfermline, emphasizing the remarkable progress the club has made under his stewardship. O’Neill’s remarks underscored the mutual respect that defines their relationship, promising an intriguing tactical battle in the final. Beyond the narrative of personal reunions, the semi‑final also showcased several emerging talents.

Grant Tamosevicius, thrust into the limelight at just 17, displayed poise beyond his years, making several competent saves and gaining valuable experience. His performance hinted at a promising future for St Mirren’s goalkeeping department. The match also highlighted Celtic’s depth, with substitutes like Iheanacho and McCowan making decisive contributions. Their impact underscored the importance of squad rotation in modern football, where fresh legs can change the complexion of a game in a matter of minutes.

Looking ahead, both clubs will now turn their focus to preparation for the final. Celtic will aim to fine‑tune their attacking rhythm, while Dunfermline will seek to exploit any defensive lapses that Celtic may exhibit. The final promises to be a showcase of Scottish football’s rich history, pitting a traditional powerhouse against a resilient underdog with a charismatic manager.

Fans can anticipate a high‑energy encounter at Hampden Park, where the legacy of the 2007 Scottish Cup final—coincidentally Neil Lennon’s last match as a Celtic player—will be echoed. The stage is set for a memorable climax to the season, with both managers eager to add another chapter to their storied careers. In summary, Celtic’s 6‑2 extra‑time victory over St Mirren not only secured their place in the Scottish Cup final but also set up an emotionally charged showdown between two footballing legends.

The match was a roller‑coaster of early setbacks, dramatic comebacks, and decisive extra‑time heroics, illustrating why the Scottish Cup remains one of the most captivating competitions in the sport.
