You wouldn't have guessed it from the opening 20 minutes, but this became a walk in the park for Rangers by full-time.
Overcoming a couple of early scares, the Ibrox side marched into the next round thanks to a penalty from James Tavernier and goals from Ryan Kent, Filip Helander and Connor Goldson.
Kent was the undoubted star man of the game, playing a significant part in all four goals and coming through big at a time in the match when Rangers were still trying to find their feet, but what about the rest of his team-mates?

Both centre-backs played well but he stood out above his partner. Also got himself on the scoresheet. Photo: SNS Group Craig Williamson

Strolled through the match with an air of poise. Passed it very well. Photo: Ross Parker - SNS Group
7. Ianis Hagi - 5
Not the best of nights for the attacking midfielder. His passing was off and he missed a great chance to make it 5-0 near the end. Photo: Craig Foy - SNS Group
8. Glen Kamara - 7
European football suits him much more than the rough-and-tumble nature of Scottish football. Great first half but faded a little after the break. Photo: Craig Foy - SNS Group
