The Bianconeri recently purchased the remaining half of the player’s contract from Udinese for €4.5 million, but they have no plans to keep him in the squad.
Following some good performances for Chile at the 2014 World Cup, Juventus hope to cash in on Isla for a fee of €8 million.
Atletico Madrid and Valencia appear to be leading the chase at the moment, although the two La Liga sides have yet to make concrete moves.
After impressing at Udinese, the 26-year-old hasn’t quite managed to prove his worth in Turin, making just 29 league appearances in two years at the club.
Isla featured in every minute of Chile’s 2014 World Cup campaign that ended with a Last 16 stage clash defeat to Brazil, who are now 23/20 to beat Holland in the third place play-off match.
