Juventus chief Marotta says Isla not for sale
Isla has been linked with Inter Milan this summer.
Marotta told the Gazzetta dello Sport: "Mauricio has been the subject of interest from Inter. We sat around a table to look at the proposal from both a financial and technical point of view.
"At this time, in agreement with the coach, we won't be putting the player on the market. Isla remains our player in every way."
