The Scottish Championship winners will face Peterhead at Hampden Park.
Mark Warburton has insisted that Rangers are determined to win the Petrofac Training Cup despite the fact that they have a Scottish Cup semi-final against Celtic coming up the week after Sunday's final, STV reports.
The Light Blues will face Scottish League One side Peterhead at Hampden Park this weekend with a chance to win a trophy they have never lifted in their illustrious history.
And while the game the week after may carry more prestige - given the opposition that stand between the Gers and a place in the final, as well as the fact that the Challenge Cup only includes teams from outside the top flight - and thus, some may have expected the club to keep one eye on the Hoops, Warburton has claimed that his side are desperate to get their hands on silverware this weekend.
"It's an honour to come here and to lead the team out," he told STV. "It's fantastic and it's really pleasing for the Rangers fans. And for the players, they've worked so hard.
"It's a trophy we haven't won as a club and it's important for us. So we're desperate to go there, deliver the performance that pleases the fans and send them home happy, hopefully."
With Rangers' recent form being shaky in comparison with the way they have played for most of the campaign - having won two of their last four games, conceding nine along the way - Warburton will know that switching off and assuming that they will dispatch their opponents from the division below could be a dangerous strategy and may result in a major psychological blow ahead of the Old Firm contest.
But by winning the game against Peterhead, they will surely have a much more positive mentality when they come up against Celtic, as well as the trophy that has eluded them during their time away from the Premiership.
