Both sides know that victory will guarantee second spot in Group B and a place in the last 16 of the competition, with Real Madrid already guaranteed to finish top no matter what they do in Copenhagen.
Gala have to win and end Juve's nine-game unbeaten run to progress, while Antonio Conte's side will still scrape through with a draw even if Copenhagen beat Madrid as they have the better head-to-head record.
Uruguayan goalkeeper Fernando Muslera should be available for Gala after making his return from a broken toe against Elazigspor on Friday night and helping the Turkish club keep their first clean sheet in 14 games.
Wesley Sneijder sat out that match but he should be fit to start tomorrow night, with both sides expected to field 3-5-2 formations.
In the reverse fixture on matchday two, the pair played out a thrilling 2-2 draw in Turin that finished with a goal for each side in the final five minutes.

Gala: Muslera; Zan, Guiselam, Chedjou; Eboue, Melo, Inan, Riera; Sneijder; Yilmaz, Drogba
Juve: Buffon; Barzagli, Bonucci, Chiellini; Lichsteiner, Vidal, Pogba, Marchisio, Asamoah; Tevez, Llorente
