Arsenal are being linked with Olympiakos defender Kostas Manolas.
The Daily Express says the Gunners are preparing to step up their interest in Greek defender Manolas - previously linked with Tottenham and Sunderland - as a replacement for Thomas Vermaelen.
Vermaelen signed for Barcelona last week after Arsenal accepted a £15m offer from the Spanish giants.
But Arsene Wenger has made no secret of his desire to bring in another centre-back following Vermaelen's exit.
Manolas has impressed at Olympiakos - including in the Champions League - since joining the club on a free transfer from AEK Athens last summer.
Manolas nearly joined Everton at the start of 2012 after AEK agreed a fee with the Toffees, only for the player to decline to opportunity to move.
