Olympiakos manager Ewald Lienen is expecting to sign Liverpool winger Albert Riera by the end of the week.
The 28-year-old Spaniard joined the Reds for €12million (£10.1m) two years ago from Espanyol, but his Anfield career never got going.
He was frozen out last season after openly criticizing then manager Rafa Benitez, and new boss Roy Hodgson is expected to let him leave the club.
Manager Lienen says the Spaniard will sign unless there is a major turnaround. He said: "Unless there is a major surprise then he will be our player.
"He is a great player who has proven his worth both at club level and for the Spanish national side."
Riera played no part in Wednesday's friendly draw with Grasshoppers in Switzerland, and manager Hodgson confirmed negotiations with Olympiakos are ongoing.
He said: "Albert Riera did not play as a precaution because negotiations are ongoing with Olympiakos."
