Paulo Sousa returns to face his old club Basel as Fiorentina target Europa League Round of 32 qualification.
It kicks off at 18.00 GMT, follow all the build-up and action from this game, Lazio-Dnipro and Club Brugge-Napoli on our LIVEBLOG.
This is a very complicated group, as Basel lead with nine points, followed by Fiorentina on six, Belenenses and Lech Poznan four each.
Basel will qualify if they win, or if the other game ends in a stalemate, while the Viola will only book their ticket today with a victory and a Belenenses-Lech Poznan draw.
Fiorentina have bizarrely lost both their home fixtures in Europe this season and won the two away (scoring six goals without conceding any), so are eager to make up for the opening 2-1 defeat to Basel.
Sousa hopes to be back here again on May 18 2016, as the Europa League Final will be held at the St. Jakob-Park.
Among the familiar names in the Swiss side are ex-Inter and Roma defender Walter Samuel, plus former Pescara and Sampdoria midfielder Birkir Bjarnason.
Samuel is not passed fit to start in the back four, but watch out for Juventus transfer target Breel Embolo in attack.
Ante Rebic sits out a ban with injured Jakub Blaszczykowski and dropped Mario Suarez, while the hosts miss trio of defenders Philipp Degen, Daniel Hoegh and Manuel Akanji.
Nikola Kalinic is supported by on-form Josip Ilicic and Borja Valero, while Federico Bernardeschi is in an attacking wide role on the right.
