Celtic manager Martin O'Neill will meet his former protégé, Neil Lennon, in the upcoming Scottish Cup final after the Glasgow side eventually triumphed over League Cup holders St Mirren with a 6-2 victory in extra time during the semi-final clash. The match began with Celtic racing to a 2-0 lead thanks to goals from Daizen Maeda and Anthony Ralston, but St Mirren produced a dramatic resurgence in the second half. Mikael Mandron sparked the comeback, netting twice, including a last-gasp equaliser in the 91st minute that forced the game into extra time.

Once the additional period began, the record champions responded emphatically. Kelechi Iheanacho scored a brace, while Luke McCowan and Benjamin Nygren each added a goal, sending the final score to 6-2 and ensuring there would be no repeat of the December League Cup final where St Mirren had emerged victorious.

The final will be staged at Hampden Park on May 23, pitting two Celtic legends against each other. Lennon's side, Dunfermline Athletic, earned their place after a dramatic shoot-out win over bitter rivals Falkirk in the other semi-final on Saturday. The stage is set for an emotional showdown that will see O'Neill's Celtic face Lennon's Dunfermline in a repeat of the 2007 Scottish Cup final – a match that also marked Lennon's last appearance as a Celtic player. The semi-final began disastrously for St Mirren when their backup goalkeeper Ryan Mullen was charged down by Maeda inside the opening minute.

The Japan international pounced on the loose ball and slid it into the net, giving Celtic an early lead. Mullen, who was covering for the injured Shamal George, made a heavy touch that proved costly. Fourteen minutes later, Mullen suffered an injury of his own and was forced to leave the field, prompting the 17-year-old Grant Tamosevicius to make his senior debut. Celtic's own defense faced a moment of danger when Viljami Sinisalo, the Finnish centre-back, was dispossessed by Mikael Mandron inside his own six-yard box.

Fortunately for Celtic, Killian Phillips failed to capitalize on the ensuing close-range chance, sparing Sinisalo from a potential early concession. Earlier, Sinisalo had produced a superb save to deny Liam Donnelly's powerful header from a corner, showcasing his composure under pressure. Tamosevicius, despite the high stakes, appeared unfazed. He made a smart save from Maeda and displayed confident footwork before eventually being beaten by Ralston just before the half-time whistle.

Ralston's strike rattled the crossbar after a clever backheel from Yang, highlighting Celtic's attacking intent. The second half saw St Mirren revive their hopes when Mandron, who had previously contributed seven goals on the team's journey to League Cup glory, headed in a well-placed cross from Declan John. This marked his first goal since December and reignited the contest.

Celtic attempted to regain control but struggled to create clear-cut chances, while St Mirren pressed hard in the final 15 minutes of regulation time. In the 87th minute, Sinisalo produced an excellent double save, yet he could not prevent Mandron's second goal in stoppage time. The French forward latched onto a through ball and blasted it into the far corner, sending the tie into extra time.

Extra time saw Celtic dominate from the outset. Substitute Kelechi Iheanacho headed in James Forrest's cross six minutes in, followed by a calm finish from Luke McCowan two minutes later. Iheanacho then struck again, finding the top corner in the 100th minute for his second goal of the period.

Benjamin Nygren completed the scoring spree shortly thereafter, sealing a comprehensive win for Celtic. Looking ahead, Celtic will face Dunfermline Athletic in a repeat of the 2007 final, a fixture that holds personal significance for both managers. Lennon's Dunfermline boss described the upcoming encounter as "an honour and a privilege" to meet his former mentor.

He reflected on his decade-long relationship with O'Neill, recalling their first meeting in 1996 when O'Neill signed him for Leicester and later at Celtic. Lennon emphasized the personal and professional bond that has endured over the years. O'Neill, for his part, expressed excitement about the reunion, praising Lennon's punditry work and his achievements at both Leicester and Celtic, as well as his recent success with Dunfermline. He looks forward to a compelling final that promises high drama and a showcase of Scottish football heritage.

The semi-final also featured several notable moments beyond the goals. Celtic's goalkeeper, after a solid performance, made several key saves that kept the scoreline respectable during St Mirren's surge. Meanwhile, St Mirren's young keeper Tamosevicius showed promise, handling high-pressure situations with composure beyond his years.

The match demonstrated the depth of talent across both squads and set the tone for a final that will likely be contested with equal passion. Fans can anticipate a thrilling climax to the Scottish Cup campaign, with both teams eager to add another trophy to their storied histories.

The final will not only be a battle for silverware but also a celebration of the enduring relationships and rivalries that define Scottish football.
