Champions Rangers are on course to finish the season with the biggest gap they have ever had over Celtic in the league.
Steven Gerrard 's side put in a dominant display at Ibrox thanks to a Kemar Roofe double and strikes from Alfredo Moreos and Jermain Defoe against the 10-man Hoops.
It puts the Premiership winners on course for an unbeaten season with just two games to go, but they are on course to pick up even more records along the way.
The Light Blues are closing in on the 100-point mark and have the meanest defence in Scottish league history - surpassing Martin O'Neill's 2001/02 Celtic.
As it stands Rangers have conceded just 13 goals this season when compared to 18 by O'Neill's side.
However, the win on Sunday also opens the door to another bragging right between the Glasgow rivals.
The biggest margin of victory in a title win
If they win their remaining fixtures against Livingston and Aberdeen, Rangers close in on some Scottish league records.
Six points would match 29-point winning margin of Neil Lennon's team of 2014 and Celtic lose the last two.
If that scenario does happen they will fall still narrowly fall short of the Brendan Rodgers' record breaking 30-point margin of victory over Aberdeen in 2016/17.
