Rangers strolled to victory over dismal and managerless Aberdeen to move above Celtic and just three points behind leaders Hearts in the Scottish Premiership.
It was critical for Danny Rohl's men to back up Old Firm victory to continue their momentum in this intriguing title race and they took the points with ease at Ibrox.
They got the start they wanted when Emmanuel Fernandez rose highest to power home from a corner 11 minutes in, and Nicolas Raskin did the same before the break from another Connor Barron corner.
It was efficient stuff from Rangers, but in truth they were given an easy ride by a meek Aberdeen, playing for the first time since the dismissal of Jimmy Thelin.
Dimitar Mitov's calamitous attempt at gathering the corner for the opener left the goal open for Fernandez, then Nicky Devlin allowed Raskin to trot across the front post and nod home the second.
Aberdeen fashioned two golden chances on the break but failed to have a strike from either as Kenan Bilalovic's touch let him down twice.
After the interval, Rangers continued to dominate and, although they could not add another goal, they nonetheless leap above Celtic in the Premiership table.
Aberdeen, who did improve offensively after the break, stay in eighth.
