The two clubs did hold negotiations about the transfer of a player who is co-owned with Udinese, but the Old Lady opted against closing the deal.
“I don’t know what will happen,” the wing-back’s agent Claudio Vagheggi told Sport Italia. “Football is unpredictable.
“They are saying that he will remain at Juventus, but you never know right up until the very last minute. We’re working.”
The Chilean joined the Old Lady from Udine a year ago, but he had a problematic first season in Turin.
Having returned to action after serious knee ligament damage, the 25-year-old appeared in just 11 League games for La Signora.
