Last season’s runners-up Fiorentina endured a tough night in Athens, falling 3-2 to Panathinaikos in a dramatic contest.
The Greek side made a lightning-fast start, racing into a 2-0 lead within 19 minutes thanks to early goals from Karol Swiderski and Nemanja Maksimovic.
However, Fiorentina responded swiftly, equalizing in a stunning four-minute spell through Lucas Beltran and Nicolo Fagioli.
The decisive moment came in the 55th minute when Tete restored the home side’s lead with a well-taken, left-footed strike, handing Panathinaikos a slim advantage heading into the second leg.
