Wolff has regularly spoken of his confidence that Ocon will find a seat on the 2020 grid, and says he would be deserving of a return.
The Silver Arrows chief told Motorsport.com: "Everyone recognises Esteban's talent, and I truly believe he should have a permanent position in Formula 1 because he is one of the best talents of his generation.
"We need to make things clear to allow him to pursue his career in a way that respects the investment and support that Mercedes have given him, obviously without closing open doors from those who showed interest in him."
Ocon has once again been linked with Renault, as Nico Hulkenberg's contract is in its final year, and Wolff suggested that his time with Mercedes could be near its end.
Wolff said: "If he is in another team he will be released regardless, he will no longer be a Mercedes driver because if you drive for another team you will be called to give the best for that team."
