Rangers head into this weekend's Old Firm clash against Celtic second in the Scottish Premiership table, but anything other than a win could see them drop to fourth at the end of matchday 35.
The Light Blues have the same number of points as Aberdeen, with only a superior goal difference separating them, while fourth-placed Hibernian trail the duo by three points.
Neil Lennon's side are looking to upset the odds by clinching the runners-up spot, and Celtic skipper and midfielder Scott Brown has tipped them to get the job done.
“They came up from the Championship and have shown everyone how good they can be."
“They definitely have given us our toughest games this season. They play good football, but they’re up for the battle."
Hibs became only the third side to beat Celtic domestically this term after securing a 2-1 win over them on Saturday.
Both teams have met on five occasions this term, with Celtic narrowly winning twice, while they were also held to 2-2 draws twice.
Rangers, on the other hand, have drawn only once with the Hoops this term, losing on three other occasions, including a 4-0 drubbing last time out.
Aberdeen have lost all three of their encounters with Celtic this term, failing to score once, while the Hoops put eight goals past them.
While Brown's dig at Rangers clearly stems from their bitter rivalry, Graeme Murty's men have failed to prove that they are really the best of the rest thus far.
However, Sunday's game gives them another chance to prove otherwise, and getting a first win in their 11th attempt will go a long way in handing them a massive boost going forward.
