Arsenal have rejected an attempt from Inter Milan for Shkodran Mustafi.
Sky Sports says Gabriel left the Gunners to join Valencia for £10 million after two-and-a-half years at the club.
And Inter made an enquiry to take Shkodran Mustafi on loan.
The German only moved to north London last summer for £35m and Arsenal will not let him leave on loan.
Mustafi was on the bench for his side's 4-3 win over Leicester last weekend.
