Arsene Wenger has sanctioned a formal approach for the Greece international after identifying him as a replacement for Thomas Vermaelen, who joined Barcelona last weekend.
The Gunners have been quoted a fee of €10 million by Olympiakos for Manolas during preliminary discussions.

The Frenchman has a long-standing Achilles problem and his availability for the early season matches is in doubt after he was substituted with the injury during the Gunners' Community Shield win over Manchester City.
Wenger wants a proven defender to join new signing Calum Chambers in providing cover for his established defensive pairing of Koscielny and Per Mertesacker, who only returned to Arsenal on Monday following the World Cup.

With three weeks of the transfer window remaining, Wenger is also in the market for a midfield anchorman who can provide cover for the centre-back position.
