Arsenal and Leicester are keeping tabs on Monaco defender Marcel Tisserand, according to reports in the Daily Mirror.
The 23-year-old is under contract until June 2019 with the French side.
It is understood the Gunners made Valencia's ace Mustafi their top target but they would reportedly consider a move for the Congo international if they failed to land the German international to the Emirates until the transfer market's deadline.
