Aberdeen last beat Celtic in May 2018, the final game of a league season that saw Celtic win their 7th consecutive title and a result that was required for the visitors to finish second in the table. Since then, the teams have met 20 times, with the Pittodrie side avoiding defeat on only three occasions.
Recent games have been an exercise in Celtic only just getting the job done. A 2-0 win on the opening day of the season was the solitary occasion more than a goal has separated the sides in the last 8 outings.
The world changed for Aberdeen on one of those games. The last time the sides met, in December, an 87th minute Callum McGregor strike turned a potential backs-to-the-wall draw into a dispiriting defeat for manager Jim Goodwin. After that, the roof caved in. Home and away defeats to St Mirren paled into insignificant to the 5-0 and 6-0 drubbings at Hearts and Hibs, either side of the Scottish Cup exit at Darvel.
Goodwin made way for Barry Robson as interim manager. A 3-1 win in their last game, against Motherwell, kept them within a point of the top six, and led to Steven Hammell’s losing his Motherwell job. No Celtic fans were surprised fortunes picked up when Barry took control. His grit and professional pride will be out toughest obstacle tomorrow. Celtic Park has seen its share of his talent.
