Serie A champion Juventus came from behind to beat Genoa 3-1 on Sunday and extend its perfect record ahead of its return to the Champions League.
Ciro Immobile gave Genoa the lead against the club which still owns half his contract, and the home side had several chances to double its advantage as Juventus seemed headed for its first league defeat since May, 2011.
However, Mirko Vucinic and Kwadwo Asamoah came on in the second half to completely change the game. Emanuele Giaccherini leveled before Vucinic gave Juventus the lead from the penalty spot.
Asamoah sealed the result eight minutes from time.
Napoli, Lazio and Sampdoria also won to maintain their 100 percent records after three matches.
Roma gave up a two-goal advantage to lose 3-2 to Bologna, which picked up its first points of the season.
