The news comes following reports in the Daily Mail, suggesting that the Swiss international midfielder would be on his way out of West London. Despite featuring 29 times in the Premier League last season, Kasami only scored three goals, and head coach Felix Magath is prepared to let him leave as the 60-year old German prepares his team for Championship football.
Magath, who has a reputation for favouring hard-working players, clearly does not see the 21-year old midfielder as an important component of his team, and Olympiacos have made a move to bring the twice-capped international to Greece.
Kasami, who arrived from Palermo in 2011, has just one year remaining on his current contract, and club officials want to cash in on his talents whilst they still can.
And now, it has been revealed on Twitter that Kasami is in Athens to complete his proposed move, with a formal announcement to be made later today.

No details have been released concerning the deal, although it is believed that the arrival of Kasami is the catalyst for Portuguese midfielder Paulo Machado to complete a move to Dinamo Zagreb.
The midfielder's low scoring season is one of the reasons he has failed to make the final 23-man Switzerland squad for the World Cup, although his absence will allow a move to be wrapped up early, benefiting both club and player.
The move represents the second piece of business between Fulham and Olympiacos in recent months, following the January arrival at Craven Cottage of highly rated Greek forward Konstantinos Mitroglou.
