The status of the Old Firm was also challenged,[16] following the logic that since Rangers 'died' during the events of 2012, the rivalry also expired and any matches played since that point would be between Celtic and a 'new Rangers', albeit playing at the same stadium, in the same colours, with the same supporters and some of the same players as before.[2][105] Adherents to this point of view refer to the club disparagingly as Sevco (the original name of the post-2012 holding company),[106] and Rangers supporters as 'zombies' or 'the undead'.[107] This difference of opinion became a new factor in the rivalry.[105]
