Neil Lennon’s side have made it four consecutive victories after defeating Ross County 2-0 at Celtic Park.
The Hoops were comfortable for the majority of the match, especially after David Turnbull gave the hosts a first-half lead, converting a Jeremie Frimpong cut-back.
Chances were missed after the break to put the game beyond doubt before Leigh Griffiths marked his first start in a couple of months with a goal, heading excellently back across Ross Laidlaw.
The Hoops remain 16 points behind Rangers but still hold three games in hand and are building up some momentum prior to the New Year clash between the sides.

1. Joe Hart
Seemed to be a little unsure of himself at the corner from which Celtic conceded but maybe his concentration had wavered with so little involvement till that point. 6 Photo: Alan Harvey - SNS Group
2. Josip Juranovic
The tight pitch at Dingwall wasn’t conducive to the sort of over-lapping runs that are a key feature of the Croatian right-back’s game but he certainly worked hard enough. 6 Photo: Craig Williamson - SNS Group
3. Moritz Jenz
A day to remember for the German centre-back thanks to his crashing 84th minute headed goal. It capped a thoroughly decent debut, the player purring through the opening half before a few splutters as he earned a booking in coming under a little more pressure in the second 45. 7 Photo: Craig Foy - SNS Group
4. Cameron Carter-Vickers
So much were County clamping down at the back, he took matters into his own hands with a mazy run into the box that almost led to a goal. Little to do defensively. 6 Photo: Rob Casey - SNS Group
