They beat Ross County 2-0 at Celtic Park
Celtic continued their domestic dominance in Scotland with a 2-0 win over Ross County at Celtic Park to extend their lead at the top of the SPL to 16 points with a game in hand.
Goals from Erik Sviatchenko and Stuart Armstrong before half-time saw the hosts complete an unbeaten domestic start to the defence of their title.
Speaking afterwards, Celtic manager Brendan Rodger said: "Once we get the goal, then, of course, the opponent has to come out a bit more. Second half, we killed the momentum of Ross County and really controlled the opening 25 minutes and created more chances.
"Last 10 minutes, I thought we could have managed the game better. We gave away too many corners and got a little bit excited," he added.
They head into the weekend's Glasgow derby with Rangers at Ibrox in a dominant league position, having beaten their rivals 5-1 in September.
Speaking ahead of the game, captain Scott Brown said it was "always going to be hard going to Ibrox no matter how many points you’re clear.
"There’s a lot of pressure on them. We’re a few points clear but you still want to go there and get the three points," he added.
SB: "No matter who we play, I play with a smile on my face and enjoy winning leagues."— Celtic Football Club (@celticfc) December 28, 2016
