Celtic survived a strong second-half fightback from Hearts to grind out a 2-1 victory in a pulsating cinch Premiership encounter at Tynecastle.
Ange Postecoglou's side looked in full control at the break after goals from Reo Hatate and Georgios Giakoumakis.
But Liam Boyce pulled one back after the break and the Northern Irish striker then missed a penalty as the hosts piled on the pressure in search of an equaliser.
