At this stage of the season, everything around Celtic feels heavier. Results matter more, margins shrink, and even the smallest details start to carry real weight.
A narrow 1–0 win over St Mirren at Parkhead did the job on paper, but it did not settle the mood. If anything, it left a lingering sense that things are not quite as comfortable as they should be.
And now, just days later, the same opponent stands in the way again. Only this time, there is no second chance.
Hampden Park is waiting.
Celtic head into their Scottish Cup semi-final knowing exactly what is at stake. League form can be corrected, performances can be improved over time, but knockout football is different. One mistake, one moment, and the entire campaign can shift.
That is what makes this particular clash feel so tense.
Because St Mirren have already shown they can hurt Celtic. Three of the Hoops’ wins against them this season have come by a single goal. Tight games, nervy finishes, moments decided by fine margins. And then there was that night in December, when everything flipped and St Mirren claimed a 3–1 victory at Hampden that still lingers in the background.
That memory has not gone anywhere. It has simply been waiting.
So the focus naturally turns to how Celtic respond. The players, the tactics, the intensity. All the usual talking points that surround a semi-final of this magnitude.
But quietly, another detail has slipped into the conversation.
And it is one that rarely gets ignored in games like this.
The Scottish FA has now confirmed the officials who will oversee Sunday’s semi-final, and Matthew MacDermid will take charge of the match. He will be assisted by Ross Macleod and David Roome, with Kevin Clancy handling VAR duties alongside Chris Graham.
On the surface, it is just another appointment.
But not everyone will see it that way.
MacDermid has already officiated three Celtic matches this season, and each one tells its own story. A defeat away to Dundee, a win over Livingston, and then the game that still raises questions, the 2–1 loss to Hibernian at Celtic Park.
That afternoon was shaped by key decisions. Auston Trusty was sent off, forcing Celtic to chase the game, and soon after, Liam Scales went down in the box without a penalty being awarded. The momentum shifted, and the result followed.
Those moments do not disappear easily.
They stay in the background, especially when the same official is handed control of another high stakes match.
At the same time, MacDermid has been involved in several St Mirren fixtures this season, adding another layer of familiarity heading into the contest. It does not decide the outcome, but it adds to the sense that everything around this game is finely balanced.
And that is the feeling that defines this semi-final.
Celtic know what is coming. Another tight contest, another game where patience will be tested, and another situation where taking chances could be the difference between progressing and falling short.
They have found ways to win these matches before. Late goals, moments of quality, flashes of leadership when it matters most. Callum McGregor’s stoppage time strike in Paisley is still fresh in the memory, a reminder of how thin the line can be.
But they have also seen how quickly things can turn.
That is what makes this occasion so difficult to predict.
Because it is not just about performance. It is about control, composure, and how the team responds when the game starts to slip into uncomfortable territory.
As Sunday approaches, everything feels on edge. Form, confidence, history, and even the officials all sitting in the background, waiting to influence the outcome in their own way.
In matches like this, it is never just about what you plan.
It is about how you react when the unexpected arrives.
And for Celtic, that could be where this semi-final is truly decided.
