Schalke chief Horst Heldt admits several clubs are keen on defender Kyriakos Papadopoulos.
The Greece international has attracted an approach from Liverpool this summer, while he is also interesting Manchester City and Chelsea.
"He actually has many clubs interested (apart from Liverpool). If it becomes concrete, we will discuss it with him," Heldt said.
"So far it's not concrete, and we are planning the season with him. Above all, he wants to really get going in training."
