Schalke would be open to bringing Mesut Ozil back when his Arsenal contract expires.
Ozil left Schalke in 2008 to join Werder Bremen, where he stayed for two years.
The German then moved to Real Madrid, spending three years in the Spanish capital before moving to Arsenal in 2013.
Ozil is out of contract next summer, and while Schalke accept a deal would not be possible immediately, they would be open to bringing their former player back in the future.
“I still have a great relationship with Mesut,” Schalke’s supervisory board head Clemens Tonnies told kicker. “We would definitely consider it [a return]. If it fits for both sides, it would be nice.
“The player could say that he returns to his roots, and that he plays football in this stadium and for those fans and the region once again. But it will certainly not happen next season.”
