The fight really begins for Kilmarnock and every side in the bottom six now in the five post-split fixtures.
The Rugby Park side have not won away to Celtic since 2012 and ending that run was always unlikely. Within 10 minutes it was a crisis management exercise in damage limitation.
Kilmarnock barely had the ball, couldn't get away from their box and very rarely got over halfway. It was the sort of afternoon no footballer wants to experience, never mind fans.
Goal difference may prove crucial - second-bottom Dundee are just a point behind before facing Hibernian on Sunday - and the second half game-management may prove helpful.
You look at this Kilmarnock squad and think they should have enough to avoid trouble, but they are right in it as things stand.
This was an afternoon they'll want to forget, regroup and get on with the job in hand.
