The 21-year-old joined the club on loan from Chelsea at the start of the season and he has enjoyed a decent start.
Traore has scored five goals and picked up four assists so far this season but some sections of the club's support have voiced their disappointment at his displays.
Maas and Traore worked together at Vitesse last season and his former coach believes Ajax need to be patient if they want to get the best out of him.
He told reporters: "When I saw him for the first time, I thought, look at him go… But at the first training session he showed unprecedented things. I really never forget.
"Dropping him isn’t an option. Why not? Because as a 21-year-old he can only learn by playing a lot."
