With the arrival of Antonio Conte as the new Juventus coach, Barzagli became an integral part of the Juventus backline, and was one of the club's most consistent performers, culminating in a recall to the national team. Juventus finished the 2011–12 season with the best defence in Italy and in Europe, only conceding 20 goals in 38 appearances. Barzagli scored his first goal for Juventus on 13 May 2012, scoring a penalty against Atalanta in the last league match of the season, in a 3–1 home win. He helped Juventus win the 2011–12 scudetto undefeated, and the 2012 Supercoppa Italiana; Juventus also made the final of the Coppa Italia that season. His stellar season earned him a place in the Serie A Team of the Year. At the end of the season, he renewed his contract with Juventus until 2015.
