The decisive moment arrived in the 83rd minute when Naderi redirected a shot from James Penrice into the net. The goal marked the 23-year-old’s eighth of the season and ensured Rangers maintained their unbeaten run of 10 matches.

Aberdeen, hampered by a lengthy injury and suspension list, adopted a defensive approach for much of the game. Despite facing relentless pressure, the Aberdeen goalkeeper Marius Müller kept his side in contention with several key saves throughout the second half.

Rangers dominated the latter stages of the match as the Aberdeen defence began to tire. Before the breakthrough, Kevin Kelsy missed a golden opportunity from six yards out, while Müller produced vital blocks to deny efforts from Badredine Bouanani and Nico Raskin.

Naderi, who has become known for his clinical finishing from close range, expressed his delight after the match. He credited the team's persistence, noting that they believed they could find a winner right up until the final whistle.

The forward said: "It feels amazing. I’m happy to be the one who scores the goals, but happy for the team. I think we deserved it. We believed we could score right up until the very end and we did."

Rangers manager Derek McInnes made tactical adjustments for the clash, moving Penrice into midfield and starting Bouanani in place of Djeidi Gassama. The changes eventually paid off as the side increased the tempo significantly after a quiet first half.

Aberdeen struggled to create clear-cut chances, though captain Kevin Nisbet went close with a header and a deflected effort that forced Rangers goalkeeper Ivor Pandur into action. The Aberdeen side was further disrupted when Emmanuel Gyamfi was forced off with an injury.

The victory sets up a final showdown for Rangers, who will face the winner of the second semi-final between Hearts and Hibernian. The final is scheduled to take place at Hampden Park later this season.

Rangers entered the contest as firm favourites, and their ability to sustain pressure ultimately proved the difference. Aberdeen will now turn their attention back to league duties following a resilient defensive display that fell just short.

The match was part of a busy weekend of Scottish football action, which also saw St Johnstone secure a 2-2 draw against Kilmarnock despite playing with ten men, and Motherwell claim a 1-0 win over St Mirren.
