The 19-year-old may snub the advances of bigger clubs next year and remain in Gelsenkirchen, according to the club's general manager
The 19-year-old has been heavily linked with a move to Chelsea during the off-season, before the Germany international drew a line under his short-term future by signing a contract extension until 2018 with the German outfit.
And Heldt is increasingly optimistic that the teenage prospect could even snub the advances of some of Europe's biggest clubs next summer as well.
He told Bild: "It is definitely possible that Draxler could stay with us for another season.
"He can get better, and of course he is in great demand, but Schalke also have the potential to improve. I don't think a 2014 is certain."
Draxler himself, though, admits he will carefully consider his future next summer should clubs prolong their interest in him.
"If there are any offers next summer I will look at them and decide what is best," he said.
"I know what I have got from my time with Schalke, but anything is possible - even a poor season."
The youngster helped his club reach the qualification stages of this season's Champions League after netting 10 times in 30 Bundesliga appearances last season.
