Gutsy St Mirren have already defeated Celtic this season and they had the natives restless last March - will they do so again tonight?
Celtic haven't tasted defeat since Stephen Robinson's side produced a performance as bold as it was emphatic back in September. Ange Postecoglou's men were outworked in the 2-0 defeat but the Irishman is acutely aware the Buddies haven't been able to produce their excellent home when out of their Paisley comfort zone.
St Mirren lost for the first time in seven games when they went down 1-0 at Hearts last Friday night and, while the Buddies boss believes confidence remains intact. They are priming themselves for a challenge at Celtic Park where the Hoops have won all 10 league games this season. But can he pull off a major upset once again in front of a packed Parkhead?
