After a good 2010–11 season, Vidal was linked with various clubs, including Bayer's Bundesliga rivals Bayern Munich. On 22 July 2011, however, Vidal joined Serie A club Juventus for €10.5 million on a five-year contract. He made his competitive debut in the opening league game of the season against Parma on 11 September 2011, coming on as a second-half substitute for Alessandro Del Piero; he marked his first appearance with a goal six minutes after his introduction in Juventus' 4–1 win at the club's new stadium. It was initially speculated that he would compete with Claudio Marchisio for a spot alongside Andrea Pirlo, but Juventus manager Antonio Conte instead played all three effectively in a three-man midfield in his 3–5–2 formation. Vidal was an integral part of the 2011–12 "Scudetto"-winning side that went undefeated the entire season. He contributed seven league goals and three assists, including crucial goals against Napoli and a double against Roma.
