At half-time it stood 0-0 between Perugia and Juventus while Lazio were 2-0 up at home to Reggina.
But due to heavy rain in Perugia, the second half was delayed as the pitch was becoming increasingly heavy.
In Rome, Lazio's final league match of the season against Reggina was suspended four minutes from time after a pitch invasion by around 500 Lazio fans. Referee Gennaro Borriello ordered the players to return to the changing-rooms. Many of them had their shirts and shorts ripped from them by supporters as they tried to leave the pitch. After a delay of around 10 minutes order was restored and Lazio won the game 3-0.
The game between Perugia and Juventus restarted after an hour's delay and with just a few minutes left of the game Perugia is leading 1-0, which means that Lazio are Italian champions.
