It has been a wild ride for the Greek side, who have traipsed across the continent pulling off a number of upset on the road to, of all places, Athens.
After finishing third in their Europa League group, Olympiacos managed to pull off a comeback from 4-1 down in their Conference League last-16 tie with Maccabi Tel-Aviv before downing Fenerbahce on penalties and upsetting favourites Aston Villa.
By contrast, Fiorentina have enjoyed a relatively smooth journey to their second successive Conference League final and are yet to lose a game in Europe this season.
This evening’s game has been made free to watch, so fans without a subscription to TNT Sports can still tune in online if they make an account.
