The second-placed Gers can move to within five points of the table-topping Bhoys with a victory over Hearts at Tynecastle tonight.
But if that materialises then Celtic - who have won 11 of their 12 Premiership matches this season - will still have three games in hand, meaning that they could potentially hold a 14-point gap over Mark Warburton's side.
Rangers have an excellent chance to consolidate second spot somewhat over the next couple of days.
Beating fourth-placed Hearts would see Rangers move six points clear of them, while they host Aberdeen - who sit two points back in third - on the weekend.
It would certainly seem as if those two are the Gers' main rivals in a campaign where Celtic have looked head and shoulders above the rest.
Asked during a press conference on the club's YouTube channel whether he is worried about Brendan Rodgers's side stretching away, he said: "No. We just focus on ourselves. The gelling process is well underway and we're learning every single day.
The Hoops have already beaten their Old Firm rivals twice this season in very simple fashion - a 5-1 Premiership win back in September, and a one-sided 1-0 League Cup victory last month.
