"I am of the opinion that Julian should play for Schalke next season. That's my personal advise to him," Tonnies told Bild.
"He should not let the interest from abroad play with his head. It's best for his development when he can play without much pressure and with a clear mind.
"Looking back, at the start of the season he was under a lot of pressure then and the exact same thing will happen again if he moves.
"There are a number of big clubs after him, but we have no intention of selling him this winter. Even if we do not qualify for next year's Champions League, that doesn't mean we will have to sell Julian."
Last summer, Draxler signed a new contract which will run until 2018 and contains a €45.5 million [£37.5m] buy-out clause.
