Basel's Urs Fischer has to play a makeshift back line, as Daniel Akanji won't be fit; fullback Michael Lang will get the start in the middle, although Walter Samuel has surprisingly recovered enough to make the bench. Jean-Paul Boëtius will make a surprise start over Shkelzen Gashi and Davide Callà. Former Fiorentina midfielder Zdravko Kuzmanovic is dropped from the starting eleven as well. Paulo Sousa, in contrast, will set out with his first-choice eleven.
Basel (4-1-4-1): Vailati; Xhaka, Suchý (c), Lang, Safari; Elnenny; Embolo, Zuffi, Bjarnason, Boëtius; Janko
Fiorentina (3-4-2-1): Sepe; Roncaglia, Gonzalo (c), Astori; Bernardeschi, Vecino, Badelj, Alonso; Ilicic, Valero; Kalinic
