The 32-year-old Frenchman is just one of several players Juventus are expected to sell at the end of this season.
"We are waiting to see what will happen at Juve in the next few weeks and then we'll make a decision," agent Antonio Caliendo said.
"It's true that Lyon and Corinthians are after him, although his objective is Milan. After all, who wouldn't go there?
"I believe that the price will be around 5m and 10m. The contract for David would be for two years."
