Craig Beattie came off the bench to score a late winner and snatch three points for Celtic in a 3-2 win at Motherwell.
Ireland's Aiden McGeady tucked home Celtic's opener on 41 minutes and Alan Thompson added a penalty on 65 after Stilian Petrov was felled by former Celtic midfielder Phil O'Donnell.
But Motherwell continued pressing and scored twice in four minutes against a Celtic side who have conceded 10 goals in four games.
Martyn Corrigan netted with a long-range strike after 67 minutes and ex Shelbourne star Richie Foran levelled four minutes later with another penalty before Beattie ended the revival when he smashed into the net on 77.
Celtic move on to 31 points from 12 games. Second-placed Rangers, with 24 from 11, face Aberdeen, in third on 22 points, tomorrow.
