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?

Even though Rangers won by four, it could have been very different without Kent. Won and scored penalty at a time where Willem were on top. Assisted on the third. Photo: Rob Casey - SNS Group
