Fiorentina thrashed Hearts, putting Hearts’ Conference League progression hopes in jeopardy.
In the first half, Luka Jovic, Cristiano Biraghi, Nicolas Gonzalez, and Antonin Barak all fired past Craig Gordon for Robbie Neilson’s side in Florence.
Inside the first two minutes of the second half, Stephen Humphrys pulled one back for the visitors, but Gonzalez restored the four-goal lead from the penalty spot.
Hearts must now win their two remaining group games against RFS and runaway group leaders Istanbul Basaksehir, while Fiorentina can only take one point from their remaining fixtures.
Fiorentina have struggled in Serie A this season, winning just two games.
They were coming off a 4-0 loss to Lazio on Monday, and Hearts, sensing a potential weakness, could not use that to their advantage.
