The latest news is that Mattia Perin will start in goal for Juventus and that Pjanic will be fit enough to start, but Bernardeschi and Khedira are out. Matuidi is only fit enough to make the bench. Cristiano Ronaldo and Mandzukic are expected to start in a 4-4-2 formation, which means Dybala will be on the bench. Cuadrado and Douglas Costa will play on the wings.
Here are the formations:
Juventus (4-4-2): Perin; De Sciglio, Bonucci, Benatia, Alex Sandro; Cuadrado, Pjanic, Bentancur, Douglas Costa; Mandzukic, Cristiano Ronaldo.
SPAL (3-5-2): Gomis; Cionek, Djourou, Felipe; Lazzari, Kurtic, Schiattarella, Missiroli, Costa; Petagna, Antenucci.
