Reports earlier this month claimed that the Chilean was hoping to be recalled from his season-long loan deal by the Old Lady after failing to settle in England.
However, the 26-year-old has claimed not to have been in contact with Juventus since arriving at Loftus Road and is enjoying the chance to play regularly after a frustrating couple of seasons on the sidelines.
He said in the Evening Standard: "That was never going to happen. People talk but I've never spoken about it. I've not spoken to a single director at Juventus since I came to England, not even to the coach there, Massimiliano Allegri.
"It is important for me to stay here a long while because I need to get match fitness back after the cruciate knee ligament injury I had [while playing for Udinese in 2012]. After playing so many games for Udinese, it was a bit of a sad situation at Juventus.
"Because of the injury and other reasons, I didn't play all that much for Juve. On the other hand, I'm playing regularly here, so I'm really happy about it."
