It was an uncomfortable first 45 minutes for Celtic in Paisley, but their relentless streak continued as they ensured there wasn't to be repeat of September's defeat against St Mirren with a 5-1 win.
Just six minutes in, Celtic would have had a distantly familiar feeling on this latest jaunt to this stadium. They took their time, but those in the VAR studio eventually suggested that David Dickinson might want to have another look at a handball claim from St Mirren that had been made minutes earlier. Alex Grieve flicked the ball on to Greg Taylor's hand from close range and after seeing a few replays, the ref pointed to the spot.
Mark O'Hara stepped up and the Buddies skipper drilled low past Joe Hart to give his side the lead. He's now scored in all three games he's played against the champions this season. Reo Hatate was presented with a big chance to draw Celtic level. The Japanese midfielder come on a netted a double when these two met in the Scottish Cup, but his accuracy was off on this occasion as he fired over from the edge of the area.
