Rangers have begun to put consistent results on the board under new boss Michael Beale and are unbeaten in eight domestic fixtures following a poor start to the season.
Minor tactical tweaks and personnel changes have made a noticeable difference in performances, though they still find themselves second in the Scottish Premiership, nine points behind league leaders Celtic.
Last time out, goals from Fashion Sakalaand Malik Tillman granted Rangers a 2-0 triumph against Dundee United at Tannadice Stadium last week.
Clean sheets have been a big part of the improvement seen at the club in recent times, as Rangers have kept three in their last six matches.
All focus will now turn to events at Hampden on Sunday, where a stiff test in Aberdeen lies waiting for Beale and his side.
Aberdeen look to have come out of a malaise just in time for the semi-final encounter against Rangers and will hope to book a place in the final against Celtic or Kilmarnock.
The Dons sit fourth in the Scottish Premiership table, having accumulated 29 points from 21 matches so far under boss Jim Goodwin.

In their most recent outing, Luis Lopesfired home a double, which gave Aberdeen a 2-0 win over St Johnstone at Pittodrie Stadium in a match that presented chances for both sides to claim three points.
That was a first three points for the Dons since November, in a run that saw Aberdeen pick up just one point from their previous five encounters.
Aberdeen will now prepare for Hampden as they look to reach the final of the Scottish League Cup for the first time since 2018-19, though Rangers will be a difficult challenge to navigate.
