The result also completed another double for Juventus, who had beaten AC Milan 4-0 in the Italian Cup in the same stadium on Wednesday.
"They say we are old and ugly but we are always the ones who win". You reach the final objective with one small step at a time. "It's hard to see these four years being repeated", Allegri said.
"If you get overwhelmed by enthusiasm, you're going to collapse three days later". Eusebio Di Francesco's Roma, in third, had already sealed their Champions League place next season after Inter Milan's 2-1 loss against Sassuolo.
"What Juve have more than anyone else in Italy is the mentality that has been built up over the years", Di Francesco told Sky Sport Italia.
"It's a club that succeeds in remaining united through difficulties". I think it's decisive that they are able to wash their dirty laundry in private and that is something all clubs ought to do, taking this mentality as an example.
Juventus had early chances with Edin Dzeko firing over, a Lorenzo Pellegrini right footer flying wide and Aleksandar Kolarov's free-kick hitting the side netting.
Paulo Dybala had put the ball in the back of the net at the start of the second half but the Argentina forward was narrowly offside. As things stand, Higuain and Dybala aren't in that category because they've not asked to leave and, as a outcome, Juventus are not putting them on the market. "We want to celebrate all together in Turin", added Allegri.
In-demand Juventus head coach Massimiliano Allegri said he will stay in Turin if he is not sacked by the Italian champions.
Chiellini is one of five players who have been involved in all seven title-winning campaigns alongside goalkeeper Gianluigi Buffon, defenders Stephan Lichtsteiner and Andrea Barzagli and midfielder Claudio Marchisio.
