Striker Kostas Mitroglou has completed his return to Olympiacos on a season-long loan from Fulham.
He arrived from the Greek club for £12m in January but has made only three appearances.
His departure was confirmed on the eve of what Whites boss Felix Magath expects to be a busy transfer deadline day.
Magath said: “We have a problem in our club that we have some players who will leave. And if they leave I need new players.
“I am sure that we will sign two or three new players at the beginning of next week so we will have another squad at the end of this period.”
