Video: Kilmarnock 0 Celtic 2
Celtic emerged with a 2-0 victory at Kilmarnock despite making a number of changes to their starting line-up.
The visitors went in front when James Forrest finished after Tom Rogic broke into the area five minutes before the break.
However, their second wasn't to arrive until the closing moments as Rogic this time set-up Callum McGregor.
A third straight triumph leaves the champions currently top of the table on goal-difference.
