Minutes earlier Kabamba had put Kilmarnock back into the game with a brilliant header. So Christopher Jullien saw it fit to reply in kind with a header of his own.
Jonny Hayes won the corner for Celtic and Griffiths put an inviting ball into the box. And Jullien was in no mood to let the chance go begging.
He did well to lose his marker with some brilliant movement and then put a bullet header past the Kilmarnock goalkeeper to make it 3-1. Game. Set. Match.
