In a dramatic semi‑final clash that will be remembered for its twists and turns, Celtic secured a place in the Scottish Cup final by defeating St Mirren 6‑2 after extra time. The match, played at Hampden Park, saw Celtic manager Martin O’Neill set to meet his former captain Neil Lennon, who will be on the sidelines with Dunfermline Athletic after their own penalty‑shootout victory over Falkirk. The game was a roller‑coaster of emotions, featuring an early two‑goal lead for the Hoops, a spectacular comeback by St Mirren, and a dominant extra‑time performance that left no doubt about Celtic’s intentions. The opening minutes were anything but ordinary.

St Mirren’s backup goalkeeper Ryan Mullen, thrust into the starting role after an injury to Shamal George, made an unfortunate error within the first minute. Daizen Maeda, the Japanese forward, seized the opportunity, slipping the ball under Mullen’s foot and sliding it into the net to give Celtic an immediate advantage. The goal was a painful reminder of the fine margins that can decide a match, especially in a semi‑final where every mistake is magnified.

Mullen’s misfortune compounded when, just fourteen minutes later, he was forced off with an injury of his own. The 17‑year‑old Grant Tamosevicius was summoned for his senior debut, thrust into a high‑pressure environment that would test his composure. Despite the nerves that such a moment can bring, Tamosevicius showed promise, making a smart save from Maeda later in the half and handling several back‑passes with confidence.

However, his inexperience was evident when Anthony Ralston struck the post just before the break, a moment that could have turned the tide for St Mirren. The second half began with Celtic still leading 2‑0, thanks to a second goal from Anthony Ralston, who capitalised on a well‑timed run to double the lead.

Yet St Mirren refused to be subdued. Mikael Mandron, a forward who had already made a name for himself in Celtic’s League Cup triumph earlier in the season, sparked a resurgence. In the 55th minute, Mandron headed in a beautifully chipped cross from Declan John, narrowing the deficit and injecting belief into the St Mirren camp. Celtic attempted to regain control, but the Scottish side grew increasingly dangerous, applying relentless pressure in the final fifteen minutes of regular time.

The tension peaked in the 87th minute when Celtic’s Viljami Sinisalo produced a spectacular double save to keep his side in the game. Yet, the drama was not over.

In stoppage time, Mandron seized a through ball, surged past the defense, and unleashed a powerful strike into the far corner, equalising at 2‑2 and sending the match into extra time. The extra‑time period was a showcase of Celtic’s attacking depth and experience. Within six minutes, Kelechi Iheanacho headed in from a James Forrest cross, restoring Celtic’s lead. Two minutes later, Luke McCowan calmly rolled the ball into the net, extending the advantage to 3‑2.

Iheanacho was not finished; he struck again in the 100th minute, firing a precise shot into the top corner for his second goal of the extra period. The final nail in the coffin came from Benjamin Nygren, who added a fifth goal for Celtic, cementing a 6‑2 victory. Beyond the goals, the match highlighted several narrative threads.

Celtic’s veteran goalkeeper Viljami Sinisalo narrowly avoided a costly error when Mandron dispossessed him inside the six‑yard box, but a quick reaction from Killian Phillips prevented a clear‑cut chance. Sinisalo also demonstrated his shot‑stopping prowess earlier, denying Liam Donnelly’s powerful header from a corner, showcasing why he remains a trusted figure between the posts. For St Mirren, the night was a mixture of disappointment and promise.

The young Tamosevicius, despite the heavy defeat, displayed composure that bodes well for his future. His performance, including a crucial save from Maeda and confident ball handling, suggests that he could become a regular feature for the club in the coming seasons.

Looking ahead, the final is set for May 23 at Hampden Park, where Celtic will meet Dunfermline Athletic. The upcoming showdown carries additional emotional weight, as it pits former teammates and long‑time colleagues against each other.

Neil Lennon, now managing Dunfermline, expressed his honour in facing his former manager Martin O’Neill, recalling their shared history at both Leicester City and Celtic. He described the prospect as "daunting" yet "a privilege," emphasizing the deep personal and professional bond that spans three decades. O’Neill, in turn, praised Lennon's achievements, noting his successful transition from player to manager and his impressive performance with Dunfermline.

The mutual respect between the two adds a compelling subplot to what promises to be a classic Scottish Cup final, reminiscent of their 2007 encounter when Lennon’s team fell short. In summary, Celtic’s victory over St Mirren was a testament to their resilience and quality, overcoming a late equaliser and dominating extra time.

The semi‑final will be remembered for its early drama, the heroic comeback by Mandron, and the decisive extra‑time display by Celtic’s attacking trio. As the teams prepare for the final, fans can anticipate a match steeped in history, rivalry, and the promise of an unforgettable climax to the Scottish Cup campaign.
