Olympiacos are reportedly hoping to sign Fulham striker Bryan Ruiz on a free transfer.
The Costa Rica international, who has one year remaining on his contract, joined the Cottagers from Dutch outfit FC Twente for £10m in 2011.
Ruiz has failed to live up to expectations at Fulham, but has attracted interest from several clubs following a string of impressive performances during this summer's World Cup finals.
The forward is keen on a move abroad following Fulham's relegation to the Championship, but the club are reluctant to allow him to leave for nothing, according to the Daily Mail.
Ruiz found the net twice for Costa Rica as his country reached the quarter-finals of the World Cup.
