The Chile international is looking forward to linking up with compatriot Arturo Vidal and is hoping that the pair can lift the Champions League trophy together
The Chile international is expected to sign for the Bianconeri next week, having already undergone a medical in Turin, and admits that he cannot wait for the transfer to be officially confirmed.
"This is a dream come true: I am going to the strongest team in Italy," Isla told Tvn. "It is important for me as a player. But it is also vital for my family. I have been working for years to get to this point.
"In Udine I became a professional. But I have always said that sooner or later I would go to a bigger club like Juve. There I can challenge for trophies. I want to play in and win something important, like the Champions League."
Isla is also looking forward to linking up with compatriot Arturo Vidal, who joined Juve from Bayer Leverkusen last summer and played a key role in the club's Serie A success.
"Two Chileans at Juve; it's historic," the 24-year-old enthused. "A great opportunity. I am very happy, he already knows everything [about the club]."
Isla, who first came to prominence during the Under-20 World Cup in Canada five years ago, is also expected to be joined at the club by his Zebrette team-mate Kwadwo Asamoah.
