Juventus played out a goalless draw with 10-man Roma on Sunday to seal a seventh consecutive Serie A title and their 34th top-flight feat.
The Turin side needed a point to wrap up the title regardless of the result of the game involving second-placed Napoli, who won 2-0 at Sampdoria.
The Old Lady, thus, added to Wednesday’s Coppa Italia success.
Head coach Massimiliano Allegri has now won the Italian double in each of his four seasons in charge.
Roma ended with 10 men at Stadio Olimpico following Radja Nainggolan’s red card.
