Holders Celtic suffered their first defeat in almost a year in the Scottish Premiership after they were surprisingly beaten by home team St. Mirren on Sunday. Celtic had not lost for 364 days before they took on St. Mirren last weekend. Ahead of the game, manager Ange Postecoglou and his players were heavy favourites to take the three points on offer. However, they failed to live up to that status after the game ended in defeat. The defending champions were handed a 2-0 defeat by their hosts.

St. Mirren produced their best performance of the season to see off Celtic thanks to a goal in each half. Scottish star Mark O’Hara gave St. Mirren the lead with two minutes left to play in the first half before English midfielder Jonah Ayungawrapped up the win for the home team in the second half. Ayunga scored eight minutes into the second half to seal the win for St. Mirren.

Celtic had started the defence of their Scottish Premiership title with six straight wins before the defeat at the hands of St. Mirren. They were flying in the league especially after the thumping of rivals Rangers in the Old Firm Derby at the start of the month. Celtic had thumped Rangers 4-0 at home to open a five-point lead at the Scottish Premiership summit.
Ange Postecoglou and his Celtic players would have been able to maintain their five-point advantage at the top of the table on the Scottish Premiership scene with an away win over St. Mirren. However, they failed in this quest mainly due to the goals from O'Hara and Ayunga either side of the half-time break. Their lead at the Scottish Premiership summit over Rangers is down to just two points after their 2-1 win over Dundee United thanks to the brace from new striker Antonio Colak.
