The Germany midfielder has been linked with Manchester City and Liverpool as his contract expires in 2026.
But Dreesen told Abendzeitung: "It is not new that we naturally want to extend the contract with one of the world's best players.
" Jamal has developed extremely well with us. He has become a player who inspires the crowd and performs spectacular things.
"Now I really hope that the good, initial talks that Max Eberl and Christoph Freund have had with Jamal lead to a final agreement.
"I don't want to set a time horizon. The most important thing is that we land an agreement."
