Philippe Clement has named his Rangers starting XI to take on Celtic this afternoon.
The Light Blues were made to sweat over the fitness of key defender Connor Goldson after the Englishman picked up a knock against Motherwell last weekend.
And it's good news for the visitors, as Goldson is fit to start the game, along with John Lundstram who has also been struggling of late.
Of course, there is no spot in the matchday squad for Fabio Silva who officially joins on loan from Wolves on January 1.
Here is how the teams line up for the big game at Parkhead...
RANGERS XI: Butland, Tavernier, Goldson, Balogun, Yilmaz, Lundstram, Sterling, Cantwell, McCausland, Sima, Dessers
Subs: McCrorie, Souttar, Lammers, Cifuentes, Matondo, Dowell, Wright, King, Devine
CELTIC XI: Hart, A.Johnston, Welsh, Scales, Taylor, McGregor, O'Riley, Bernardo, Maeda, Palma, Kyogo
Subs: Bain Abada, Yang, Turnbull, Nawrocki, Oh, Hatate, Ralston, M.Johnston
