Juve are expected to launch a serious challenge to the two Milan clubs this year and made a big statement in their first league fixture at the Juventus Arena.

Stephane Lichsteiner (15), Simone Pepe (58), Arturo Vidal (73) and Claudio Marchisio (83) were the scorers in a match that also saw Andrea Pirlo excel.

Paolo Di Ceglie was sent off for a last-minute foul, allowing Sebastian Giovinco to pull back a consolation from the penalty spot.

Fiorentina were 2-0 winners at home to Bologna, Alberto Gilardino putting a summer of transfer speculation behind him with the 20th-minute opener.

Alessio Cerci then followed up two minutes into the second half and the visitors could not respond.

Roma boss Luis Enrique's awkward start at the club continued with a 2-1 home defeat at the hands of Cagliari.

Daniele Conti gave Cagliari the lead after 68 minutes and Roma's Jose Angel saw red moments later before Moestafa El Kabir and Daniele De Rossi traded late goals.

Udinese enjoyed a 2-0 victory at Lecce.

Goals from Dusan Basta and the impressive Antonio Di Natale inside 16 minutes settled any nerves but there was to be no further scoring.

Genoa and Atalanta shared four goals in an entertaining draw at the Stadio Luigi Ferraris.

Miguel Veloso put the home side in front after only six minutes, but Maxi Moralez then scored twice to turn the tables.

Giandomenico Mesto earned Genoa a draw with the fourth goal of the game in the 55th minute before the hosts lost Valter Birsa to a last-minute red card.

Novara celebrated a point in their first top-flight fixture for 55 years after a 2-2 draw at Chievo.

Sergio Pellissier and Cyril Thereau gave Chievo a two-goal lead after 25 minutes before Francesco Marianini and Massimo Paci, four minutes from time, hauled the new boys level.

Elsewhere Catania and Siena shared a goalless draw.
