Rangers cut the gap at the top of the Premiership to two points after winning 1-0 away to Celtic.
Derek McInnes’ men recorded their second Old Firm win within seven days, backing up last weekend’s 3-0 Premier Sports Cup triumph at Ibrox with this deserved triumph in the league.
German striker Ryan Naderi scored the only goal of the game on 33 minutes, reacting quickest inside the penalty box to net after Kim Minsu’s strike was parried back into the danger area by Celtic goalkeeper Viljami Sinisalo.
Rangers created the better of the chances and had a second-half goal by Olwethu Makhanya disallowed for handball in the build-up.
Rangers remain in second place in the standings, but are now just two points behind the champions, who suffered their first league defeat of the campaign.
The spotlight will now fall on Celtic boss Martin O’Neill, who has presided over three poor defeats in the space of a week.
The domestic game now shuts down for three weeks, with an international break coming up.
We give the players a mark out of ten for their performances at Celtic Park.

13. James Penrice
The usual left-back was asked to push into midfield once again and lock on to Celtic's forward-thinking players. He was combative and part of a Rangers unit that harried Celtic all game. Emptied the tank and was replaced by Godfrey. 7 | Getty Images
14. Nicolas Raskin
Showed all his experience of previous Old Firm games. Was up for the fight all afternoon. 7 | SNS Group
15. Luke McCowan
A surprise starter, the maligned midfielder had a rotten afternoon. Wasteful with the ball and irked the crowd with his performance. Understandably hooked at the break for Hogh. 3 | SNS Group
16. Benjamin Nygren
Another big match where the Swedish attacking midfielder played on the periphery. Rarely involved in attacking moves. Threw his hands up in the air in frustration after being subbed on 62 minutes. 4 | SNS Group
