St Mirren captain Mark O'Hara is on a personal mission this season, driven by the bittersweet taste of a trophy won from the sidelines. The midfielder was injured and unable to play in December's historic League Cup final victory over Celtic, a triumph he could only watch from the bench.

Now, with a Scottish Cup semi-final against the same opponents looming this Sunday, O'Hara is fueled by a sense of unfinished business. He's determined to help his team pull off another Hampden Park upset and earn his place on the pitch for a potential final, chasing what he calls "the stuff of dreams and the stuff of legends"—a remarkable cup double.

"Part of me, selfishly, felt it would have been nice to be playing," O'Hara admitted, reflecting on the League Cup win. "It does feel a bit like unfinished business... to win a cup with full involvement."

St Mirren will draw confidence from their recent performances against the Scottish giants. They've pushed Celtic close in league matches, including a narrow 1-0 defeat last weekend, and already know what it takes to beat them at the national stadium. "We've beaten them at Hampden already this season," O'Hara stated. "We're confident we've got enough in the building to go and cause an upset."

For O'Hara, these high-stakes occasions are not to be taken for granted. After years without a Hampden appearance, reaching two major semi-finals in one season is a special opportunity. His story is one of resilience and hunger—a captain leading from the front, eager to write his own chapter in the club's history from the center of the pitch, not the sidelines.
