Celtic twice came from behind earn a share of the spoils at Parkhead.
Ange Postecoglou's side were never really at the races in this one with St Mirren deservedly picking up a point on the road. Curtis Main opened the scoring by capitalising on a horrible mistake at the back between Anthony Ralston and Tomoki Iwata before firing beyond Joe Hart - who really should have done better with the effort.
However, Kyogo Furuhashi levelled with his 31st goal of the season by firing high beyond Trevor Carson but the visitors, who impressed in the contest, once again found themselves in the lead as Main headed beyond a helpless Hart. Skipper Callum McGregor rescued a draw with a fine effort from outside the box in the final stages. Here's how we rated the champions.
