The former Bayer Leverkusen man committed his future to the Bianconeri and admitted that it will be hard for the club to retain their Serie A crownJuventus midfielder Arturo Vidal is not paying attention to speculation over his future and insisted he is happy with life in Turin.
The Chile international has been associated with Real Madrid in recent weeks after impressing for the Serie A champions in his first season at the club following a €10.5 million (£8.2m) transfer from Bayer Leverkusen last summer.
"I am not interested in any other clubs," Vidal told reporters at the Bianconeri's pre-season training camp in Chatillon. "I am happy at Juventus.
"The groin problem which affected me at the end of last season is gone. I am fine, but also tired.
"These days we are working hard to be prepared for the start of the new season."
Juve enter the new campaign as favourites to win the Scudetto after an impressive title-winning campaign in the league in 2011-12 in which they were unbeaten.
"We have improved further now and we know that we are strong," the Chilean added. "But we must prove it on the field and not by talking.
"We know that this will be a difficult season, in which we will be playing in several different competitions. That is why we are working so hard now.
"The Supercoppa Italiana against Napoli? We have not forgotten the defeat against them in the Coppa Italia final and we want revenge."
