Albert Riera is expected to complete his transfer from Liverpool to Olympiacos later this week.
The 28-year-old Spaniard has spent the last two seasons at Anfield following his switch from Espanyol but struggled to hold down a regular first-team place during that time.
He scored five goals in 45 starts and 11 substitute appearances for the Reds but was frozen out of Rafa Benitez's starting eleven after criticising the former Valencia coach.
The Greek club's coach Ewald Lienen said on Wednesday: "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."
Liverpool suspended Riera in March after he said: "If I'm doing something wrong and you are my boss and you count on me, then why not come and tell me what I need to do to play? That's what really hurts.
"Torres and Reina encourage me. They tell me that they know that if I play, I will do well. But a week goes by and then another and another and nothing has been achieved. There shouldn't be a lack of communication either, because I speak Spanish and my English isn't bad either.
"In the two years I have been here Benitez has never managed a situation with a player by talking to him. He thinks he is the boss and everyone else is deaf. The dialogue with the players is practically zero."
