Juventus coach Antonio Conte expects an ultra competitive Serie A title battle.
Juve will start the campaign as favourites.
"The values of clubs are changing, our rivals are getting stronger," he told the Gazzetta dello Sport. "It will be a very open championship.
"Juve, Milan and Inter are traditionally title contenders. Napoli have spent 75m-80m and have reinforced with Rafael Benitez, a great Coach who has won it all.
"Fiorentina have legitimate hopes. Not only do they have Mario Gomez, but also Giuseppe Rossi, who some are maybe underestimating.
"Lazio have amplified their squad and are tough, tactically strong.
"Roma, meanwhile, will try to invest the money they got for Marquinhos [32m from Paris Saint-Germain]. They should be complimented for that move, that was a great deal."
