Callum McGregor fired a spectacular winner deep in stoppage-time as Celtic cut the gap on Scottish Premiership leaders Hearts to four points with a 1-0 victory over St Mirren.

The Celtic captain struck into the top corner from 25 yards to earn a win that looked unlikely for the majority of the game in Paisley.
