Celtic's 100 per cent start to the season is OVER as St Mirren caused a major upset in Paisley.
Ange Postecoglou and his troops arrived for the Sunday lunchtime kick-off with six wins from six under their belts, scoring a whopping 25 goals in that run. The Aussie boss decided to ring the changes with six faces from the midweek Champions League draw with Shakhtar Donetsk in Warsaw including Reo Hatate and Jota dropping to the bench with key defensive duo Cameron Carter-Vickers and Josip Juranovic missing out completely.
Mark O'Hara and Jonah Ayunga were the heroes for the home side as Stephen Robinson and Co picked up a major scalp. The results means Celtic failed to restore their five-point advantage at the top of the Premiership standings with Rangers' home win over Dundee United coupled up with this defeat meaning the gap is down to two points ahead of the international break.

Here are three things we learned from Celtic's first defeat of the domestic season.
Too many changes?
Ange Postecoglou rang the changes for this one with six in total.
The likes of David Turnbull, Aaron Mooy and Liel Abada came in with Reo Hatate, Matt O'Riley, Jota and Giorgos Giakoumakis amongst those on the bench.
The Hoops struggled in the first 45 minutes to create any real openings or play with that usual attacking style. Things didn't improve in the second in an afternoon to forget for the champions.
A lesson learned for the future?
Unbeaten run gone
Celtic's 100 per cent start to the Premiership season is officially over.
They had won six from six going into this one and had only conceded one goal.
But St Mirren fired home twice in Paisley to cause a major upset.
Mark O'Hara and Jonah Ayunga were the men on target for the home side.
It also brings an end to a long unbeaten run that stretches just shy of a year by a single day.
Title battle twist
Rangers returned to winning ways at Ibrox on Saturday as they defeated Dundee United 2-1.
It brought an end to three heavy defeats on the spin and it turned out to be a big result.
The gap at the top is now reduced to two points after Celtic's failure to win at St Mirren.
There will be plenty more twists and turns to come across the course of the season.
