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.
