Arturo Erasmo Vidal Pardo is a Chilean footballer who plays as defensive midfielder for Juventus and Chile. Vidal is a versatile box-to-box midfielder capable of playing in defensive and attacking roles and was nicknamed Il Guerriero ("The Warrior") by the Italian press for his hard-tackling and tenacious style of play.

After a good 2010–11 season, Vidal was linked with various clubs, including Bayer's Bundesliga rivals Bayern Munich. On 22 July 2011, he 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, 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. It was initially speculated that he would compete with Claudio Marchisio for a spot alongside Andrea Pirlo but Conte instead played all three effectively in a 3-man midfield. 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.
