Connor Goldson
The defensive stalwart missed over two months earlier this season. The ex-Brighton man hasn't been absent a whole lot in his Rangers career and his comeback was a welcome one. After he returned in the 3-2 win over Aberdeen at Pittodrie, Goldson has helped Rangers keep clean sheets in three of their last four games, the outlier being the 2-2 draw with Celtic. He'll have his hands full on Sunday against a potent Aberdeen attack featuring leading goalscorer Bojan Miovski. Limiting the threat from the Dons will give Michael Beale's men the perfect platform to win the game.
James Tavernier
The captain is a regular goalscorer, both from the penalty spot and open play, and he's someone Aberdeen will need to be mindful of as he makes those thunderous runs from deep to attack the opposition area. Tavernier, too, will have to focus on his defensive duties as he goes up against one of the most exciting players in the league - former Benfica B winger Duk, who netted twice in the 2-0 win over St Johnstone last weekend.
Ryan Kent
It's likely to be Alfredo Morelos who starts in the central striker role, although it could be top scorer Antonio Colak. What we do know is that Kent will play on the left flank. The former Liverpool winger has all the talent but one criticism of him would be his lack of consistency. If this can be one of the games in which he dominates the opposing full-back and terrorises the defence then Rangers will be very difficult to beat at the National Stadium.
