Quote MessageIt was a brilliant run from Ryan Flynn. He saw the space and went for it. Now they have the extra man, they can afford to make those sort of runs

HT: St Mirren 0-0 Celtic
St Mirren will definitely be the happier of the two sides at the break but slightly disappointed they have not gone ahead - they've had the chances.
Celtic did come close to scoring before losing Olivier Ntcham to a red card. The visitors are still very much in this game, despite only having that one Dedryck Boyata effort on target.

It looks like Celtic have moved to a back four with Kristoffer Ajer moving to right-back and Kieran Tierney moving back to left-back.
Tierney had started further up the field with Ajer alongside Dedryck Boyata and Filip Benkovic in central defence.

Quote MessageAbsolute madness. When you are on a booking, you know you don't lunge into tackles. It's almost as if he was on a death wish to get sent off. You don't go for the ball in that type of manner when you are on a booking

Quote MessageIf Craig Gordon got a finger to it, it was a brilliant save, because it was hit with venom

Quote MessageHow can Kristoffer Ajer be out-jumped at the back post? He is 6' 4"
St Mirren 0-0 Celtic
