Juventus won a fifth consecutive Serie A title after Napoli failed to beat Roma on Monday.
Napoli had to claim all three points at the Stadio Olimpico to keep their slim hopes of catching Juve alive but were defeated 1-0 by third-placed Roma as Radja Nainggolan struck a late winner.
Juventus have officially won 32 Scudettos, and two more league titles were later revoked following a referee scandal.
Massimiliano Allegri’s side last lost on Oct. 28, when a 1-0 defeat to Sassuolo left them 11th in the table, but they have since taken 73 points from a possible 75 to move clear at the top.
Following the Sassuolo result, the Old Lady had 12 points from 10 games and were 11 points off the summit.
Juventus watched the game at their Vinovo training centre on Monday and later came outside to celebrate with fans at the gates.
Juventus lost in the Champions League to Bayern Munich in the round of 16, but they are also looking to defend the Coppa Italia in the final against AC Milan on May 21.
This is the fourth time a team have won five straight Scudettos. Juventus previously accomplished the feat from 1931-36, while Torino were champions from 1943-49 and Inter Milan from 2006-2010.
Among Europe’s top five leagues, only Real Madrid in Spain (1960-65 and 1985-90) and Lyon in France (2001-08) have also won at least five league titles in a row.
