The Chile international insists he is ready to return to Turin after the World Cup but that his coach will decide where he plays his club football next season
The 26-year-old has impressed at right-back at the World Cup so far this month, helping his country to victory over Australia and a famous 2-0 humbling of reigning world champions Spain.
But despite being a regular in Jorge Sampaoli's Chile side, Isla has struggled to merit a regular berth at the Juventus Stadium since arriving from Udinese in 2012 and made just 18 Serie A outings last term
"I am working hard for both Chile and Juventus, so everything is good for me,” he said.
"Will I stay at Juventus? I know that all the fans support me. Everything will depend on the coach.
"I have learned from many players at Juventus and will continue to work.
"If the coach wants me to keep me then I am glad, because I want to do my best at the World Cup and then return soon to Juventus."
Isla has been linked with a move to a number of European clubs including Arsenal and Liverpool.
