The timing was perfect, and the midfielder racing in finished it off.

That goal didn’t just give Celtic the lead; it blew apart St Mirren’s defensive game plan. The visitors suddenly had no choice but to ditch their disciplined approach and push up in search of a goal.

Celtic vs St Mirren: Tactical Breakdown: How Celtic’s 4-3-3 Unlocked St Mirren’s Compact Shape

Let’s talk tactics. This match played out like a chess duel. Celtic stuck with their tried-and-true 4-3-3, staying wide and moving the ball quickly. Their full-backs surged forward, pushing St Mirren’s wingers deep and squeezing the visitors into a compact 4-2-3-1. The first half? Pretty tight, with both sides working hard but barely any clear-cut chances.

But here’s something most folks missed: when Celtic had the ball, their three midfielders kept rotating, always pulling St Mirren’s double pivot out of position. It wasn’t just about effort; it was smart play. With a pressing intensity measured at a PPDA of 7.2, Celtic kept St Mirren from building attacks, a stat BBC Sport highlighted.

Once they went behind, though, St Mirren lost their tactical shape. They switched to two up front, leaving the defense exposed. Celtic saw this, and started doubling their progressive passes per sequence in the last 30 minutes. Honestly, that’s how you force an opponent to take risks.
