Germany coach Joachim Low has confirmed Werder Bremen defender Per Mertesacker is set to sign for Arsenal.
Reports suggest he could be available for as little as around £8million because of Bremen's financial problems.
Wenger has long been linked with Mertesacker, who is currently on international duty.
Germany boss Low said on Tuesday: "Per contacted me last night and informed me (about Arsenal's interest).
"I told the player that I would release him for the day."
