Nice have turned around a 2-0 deficit to Evian to snatch victory at the death through a last-gasp Neal Maupay winner.
It was a fantastic start for the visitors and after just three minutes Sagbo opened the scoring with the first chance of the game.
Nice started to up the pressure and won a series of corners but it was Evian who went 2-0 up instead, Cedric Barbosa finishing from Saber Khalifa's assist in the 14th minute.
Nice reduced the deficit on the 20-minute mark with Dario Cvitanich being set up by Romain Genevois to get the hosts back in the game.
Nice started to get on top with Cvitanich heading wide and Eric Bautheac having a shot well blocked in the 30th minute.
Just two minutes into the second half and the hosts were level and it was again Cvitanich, this time set up by Valentin Eysseric.
Nice were now looking most likely to win and Khalifa shot wide before Brice Dja Djedje's shot was saved.
The scene was set for a late winner and Maupay duly obliged deep into stoppage time.
