Schalke is close to signing Arsenal defender Shkodran Mustafi claims Sky Sport journalist Max Bielefeld.
The German footballer has agreed on a six-month period contract with the Gelsenkirchen club.
It is not clarified whether Schalke will buy Mustafi back from Arsenal or whether he will terminate his contract with the Londoners himself.
This would therefore allow Schalke to release 20-year-old Ozan Kabak to Liverpool. The English side is reportedly loaning him out with a buyout option for €30m.
