Serie A champion Juventus came from behind to beat Genoa 3-1 yesterday 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.

In Naples, Napoli got off to the perfect start when Parma goalkeeper Antonio Mirante brought down Goran Pandev in the third minute. Edinson Cavani stepped up to the spot and fired his penalty into the right hand corner, past Mirante's outstretched hand.

Pandev got on the scoresheet in the 39th minute after Marek Hamsik raced clear and unselfishly slotted the ball across goal for the Macedonia striker to stroke home.

Marco Parolo got Parma back into the game on the stroke of halftime, shortly after Napoli midfielder Blerim Dzemaili had hit the right hand post with a free kick.

Lorenzo Insigne, who had a fantastic debut for Italy midweek, scored his first Serie A goal to seal Napoli's 3-1 win.
