Jali has found his opportunities limited this season, though he has started their last two games in the Jupiler League Championship play-offs.
Oostende have already exercised an option to extend the Bafana midfielder’s contract to the middle of next year.
“He has had a difficult season and is underestimated and undervalued,” Tountouris told the Belgian website voetbalnieuws.be.
“However, Oostende took the option until mid-2018. Jali misses the game because he played little, but you see in the recent play-off matches that he has many qualities. We think it’s time to move on and we are working on a solution. Return to South Africa? Those rumours do not have to be believed because he is only 27 years old and has many great years ahead.”
