German defender Christoph Metzelder has revealed that he will leave Schalke at the end of this season.
The 31-year-old's current contract runs out next summer and he admits that there is little chance of him being offered a new deal by the Royal Blues.
"I assume that I am leaving Schalke next summer," he told Bild. "That is my plan.
"It's really your duty when you see young talents knocking on the door.
"It is not clear [where I will be playing next season]. It will depend on what options I will have at the time."
Metzelder joined Schalke from Real Madrid in 2010.
