After a nervy and tense first 50 minutes at Ibrox, Celtic fans were soon going wild thanks to two goals in the space of 15 minutes which made things a lot more comfortable for the champions.
After Rogic thumped one home from close range thanks to an awful mishap in the home side's defence, Lee Griffiths added the second thanks to a beautiful through-ball from Patrick Roberts.
The man on loan from Man City picked up the ball on the right wing before cutting inside and sliding a perfectly weighted pass into the path of Griffiths who finished excellently on his weaker foot.
He then picked up a Celtic scarf for the celebrations and really took time to drink in the misery he had just compiled on the Rangers fans.
Such a lovely ball through from Roberts, it's no surprise they love him so much up there.
As for Griffiths, you can tell he really enjoys playing in these games, and after keeping his cool in front of goal it was clear to see what the insurance of a second goal meant to everyone involved.
