Napoli were beaten 3-2 by Bologna as Arthur Rowe's injury-time goal snatched the points for the visitors on Matchday 36 of Serie A.
The Azzurri made a poor start and found themselves 2-0 down after Federico Bernardeschi's fierce finish and a Riccardo Orsolini penalty.
However, Antonio Conte's side rallied before the break and Giovanni Di Lorenzo – making his first start since sustaining a knee injury in January – pulled one back to make it 2-1 on the stroke of half time.
Alisson Santos levelled the scores soon after the restart with a fine finish from Rasmus Hojlund's pass but Napoli were unable to push on and find a third.
With the matched seemingly headed for a draw, Rowe scored a stunning acrobatic goal to clinch the win for Bologna.
