A tremendous second-half performance gave Rangers a resounding victory over Aberdeen at Ibrox.
Steven Thompson knocked in the opening goal towards the end of the first half.
Midway through the second half, Peter Lovenkrands clipped the ball past Ryan Esson and then Nacho Novo rounded the keeper to coolly score.
Fernando Ricksen scored the fourth with a long-range effort before Novo made it five with a penalty after he had been fouled by Phil McGuire.
Fernando Pasquinelli tested Stefan Klos from 25 yards but the German gathered low down at his left-hand post.
Rangers applied concerted pressure to the Aberdeen goal for a 10-minute period but the Dons' keeper Ryan Esson was not really tested.
In fact it was Klos who was forced to race from his goal as Darren Mackie burst through following a Jean-Alain Boumsong misjudgement.
The Aberdeen striker got to the ball first and hit the deck as Klos came flying out, but the referee signalled for a goal kick.
There was a lengthy delay following a clash of heads between Scott Severin and Dado Prso, with the Rangers striker unable to play on because of a nasty gash above his eye.
Prso's replacement was the man who broke the deadlock shortly after his introduction.
Klos saved well from a close-range effort by Mackie and the ball broke to Thompson, who drove upfield and though Aberdeen appeared to have cleared the original danger, Severin took a clumsy touch as he kept the ball in play.
That allowed Novo to flash the ball across goal and Thompson stuck out a leg to divert the ball into the net off the post.
Thompson celebrates the opening goal
Aberdeen attempted to take the game to Rangers more at the beginning of the second half, but Klos was untroubled and it was Esson who had to block a near-post shot by Novo after 57 minutes.
The visitors did threaten shortly afterwards when Mackie burst through on the right. He cut the ball back to John Stewart who rifled a shot just off target from the edge of the box.
But Rangers made sure of the points in 68 minutes. Fernando Ricksen threaded the ball through to Lovenkrands and with the Aberdeen defenders claiming for offside, the Dane tucked the ball coolly past Esson.
Lovenkrands passed up the chance of a second when he blasted the ball into the side-netting and Novo dragged a shot wide.
But the Spanish striker did extend the lead with 15 minutes remaining as he collected a long pass from Zura Khizanishvili, rounded Esson and side-footed the ball into the net.
Thompson had a flashing header cleared off the line but Gregory Vignal tapped the clearance to Ricksen who thumped the ball past Esson from 22 yards.
Moments later Rangers made it five when McGuire held Novo down in the area and the striker made no mistake from the penalty spot.
