Juventus striker Mirko Vucinic feels the title race is a battle between themselves and AC Milan.
The pair went into the Christmas break joint top of the standings, two points clear of Udinese and four ahead of Lazio. Inter, Napoli and Roma follow.
"In my opinion, the title will be limited to just us and Milan," he told the Corriere dello Sport on Monday.
"I think we have more desire to improve and work than Milan, while we also have Andrea Pirlo in our team."
Pirlo left the Rossoneri for Juve during the summer and he was followed to the club by Vucinic after he opted to leave Roma.
"Juventus, compared to Roma, is something totally different," the Montenegrin continued. "I'm not saying that there was no organisation in Rome, but here you feel the weight of history.
"I've also never trained so hard as under boss Antonio Conte."
