The Dutch winger found first-team chances limited throughout the season and has been tipped to leave Anfield.
But his representative, Winnie Haatrecht, insists that is not the case and he hopes to hold talks soon with Reds manager Rafael Benitez.
"He is not done here yet," Haatrecht told AD Sportwereld.
"I will sit down soon with Mr Benitez to evaluate the season. We haven't found time to do that yet.
"Ryan went from Ajax to Liverpool to win trophies. So far that hasn't happened. Ryan wants to leave Liverpool as a regular starter with a trophy in his pocket."
The 22-year-old made six starts all season and was a substitute 21 times.
