The Rangers v Hearts encounter was a top-of-the-table clash for the ages and Rangers' comeback ensured they very much remain in contention for the title.
It was a performance and result that simply could not have happened earlier in the season as Rangers showed a grit and determination along with a clinical edge that had been missing under Russell Martin.
That short-lived era has been gradually erased from the memories of the club's supporters who are now revelling in the possibility of a turnaround in their season most would not have deemed conceivable when Danny Rohl took over in late October.
But since then, Rangers have taken 11 points more than Hearts and nine more than Celtic (from one game more) to give themselves a fighting chance of reclaiming the Premiership title.
His January signings all made significant contributions to Sunday's victory. Tuur Rommens' energy and strength on the left flank, allied to good crossing ability, make him a force to be reckoned with. Tochi Chukwuani has also added a powerful edge to the midfield as well as an element of guile that had been lacking previously.
In attack, Andreas Skov Olsen is improving with every passing game and could have a huge role to play in Rangers' quest for a league and cup double, while Ryan Naderi - although not on the scoresheet against Hearts - showed terrific positional awareness and a desire to put himself about.
Questions remain over Rohl's team selection against Motherwell last midweek. Rommens and Skov Olsen might have made the difference and Rangers could be in an even better position but the manager has earned the right to make the calls he believes are best for the team and given what he has achieved so far, it's difficult to be too critical.
