Borussia Monchengladbach director Max Eberl says the club have an option to extend Thorgan Hazard's contract.
But Eberl says Gladbach could retain the former Chelsea winger should he want to remain at the club.
"He told us he wants to see where we play in the end," Eberl said according to Transfermarkt.
"Yes, he is interesting for other clubs. Nevertheless, we have a chance to extend with him if we succeed on the field. But if Thorgan still says he wants to take the next step, then it must be next summer.
"I can not do without this money. Of course we will have to be creative if we want to extend it with him. But there are situations right now, you have no chance."
