That’s a Napoli fan channel (the moron with the microphone is Carlo Alvino, massive anti-Juventino POS) they were following the Lazio V Juve game which was being played just before Napoli V Roma.
They were convinced the game finished 0-0 and were prematurely celebrating that fact, as Napoli was to play Roma straight after and they had a chance to gain more ground on us in the league race.
They then soon realise that the game hadn’t finished 0-0 and that Dybala had scored in the 95th minute and their joy was very short lived indeed

And anyway, Napoli lost 4-2 against Roma straight after to make matters worse

Was a classic night.
