The goalkeeper has been linked to several exit links this window and might likely be heading towards the door as Schalke open talks.
Emiliano Martinez is the subject of interest from Schalke – according to Sky Sports.
The 27-year-old is contracted to remain at Emirates Stadium until 2022, but it has been suggested that he could leave the club this summer.
Schalke are ready to pounce, but Aston Villa have also been linked with Martinez in recent weeks.
Martinez who has been backup to first-choice Bernd Leno, sees his Gunners deal expire in 2022.
