Rangers edged out Hibernian with a 1-0 win on Saturday afternoon, earning a remarkable 18th victory in league 20 matches as Steven Gerrard's men took another step towards ending Celtic's grip on the title.
The Gers faced off against Hibs in a huge top-of-the-table clash, where Celtic boss Neil Lennon would have been hoping for a favour from his former employers.
It wasn't to be for Hibs or Lennon however, after they slipped to a 1-0 defeat at Ibrox, thanks to Ianis Hagi's first-half strike. The decisive blow was dealt in the 33rd minute, when Kemar Roofe's low ball across the face of goal was turned into the net by the Romanian at the far post.
Rangers restricted the visitors to only one shot on target over the 90 minutes, extending their incredible defensive record for another week. That shutout meant that Gerrard's men have only conceded an unbelievable five times in 20 league matches, which, combined with the impressive 54 goals scored, gives the league leaders an incomparable goal difference of 49.
This stunning set of results since the beginning of the new season has thrust Rangers into the most commanding of leads at the top of the Premiership, standing 19 points above Celtic, although the Hoops do hold four games in hand on the pace-setters.
Having said that, Celtic would still be languishing seven points behind Gerrard and co should they collect a maximum return from those matches - something which remains far from certain given their own poor form this year.
The games in hand may offer Celtic supporters hope that the title race is not over just yet, but that flicker of optimism may be extinguished come 2 January, when they travel to Ibrox to take on the undefeated leaders.
The Hoops' ambitions of securing an unprecedented tenth successive league title are hanging by a thread, but with the unstoppable form that Rangers are showing, those hopes may already be dashed.
Brace yourselves Scotland, you might be witnessing a new set of champions for the first time in a decade.
