Charles De Ketelaere will likely rest in Atalanta’s away Europa League game against Strum Graz and the same is true of Nico Gonzalez in Fiorentina’s Conference League match against Čukarički at the Stadio Franchi.
Atalanta meet Strum at 17:45 BST.
Only two players are not available for Gian Piero Gasperini: José Luis Palomino and El Bilal Touré.
Teun Koopmeiners has travelled with his teammates to Austria after missing the most recent Serie A game due to an injury. He or Mario Pasalic will start behind Gianluca Scamacca and Ademola Lookman.
On the other hand, Fiorentina host Serbian side Čukarički at the Stadio Franchi, where Vincenzo Italiano is expected to rotate more than Gasp. It kicks off at 20:00 BST.
Oliver Christensen will likely replace Pietro Terracciano in goal. Nikola Milenkovic and Nico Gonzalez are expected to start on the bench, while Lucas Beltran will be given a new chance in attack.
Cristiano Biraghi is injured and Giacomo Bonaventura is not available, so Antonin Barak will replace the ex-Milan man as an attacking midfielder with Maxime Lopez and Rolando Mandragora in the middle of the park.
