It was their fourth league title under the guidance of Massimiliano Allegri, who also becomes the first coach in Europe's four leagues to win four consecutive domestic doubles of league and Cup titles.
"They say we are old and ugly but we are always the ones who win".
"In the Champions League the difficulties are higher than those in the championship, but we have this goal ahead of us and we will definitely go for it again next season". "Credit goes to the lads for keeping their cool, taking things one step at a time towards our final objective".

Nainggolan received two yellow cards in the space of five minutes and from the 68th minute Roma were down to 10 men.
It mattered little as Juventus clinched the title with only a match against already-relegated Hellas Verona to play.
"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 is also a solid and united club, even in hard times".
A number of players could leave Juventus at the end of the season, notably club captain Gianluigi Buffon, although the veteran goalkeeper has yet to confirm his retirement. 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.
"When the next season begins, we all start from zero points and must continue proving we are competitive".
Meanwhile, Atalanta held AC Milan to a 1-1 draw, threatening the latter's hopes of finishing Italian league play in a Europa League position.
With this draw, Milan have 61 points and remain in sixth place, which secures them a berth in the next edition of the Europa League, while Atalanta are just one point behind Milan in seventh position.
