Congolese international midfielder Delvin Ndinga has joined Olympiakos on loan for the remainder of the season from Monaco for an undisclosed fee, the Greek champions announced on Saturday.

Greek press reports said that Olympiakos have an option to purchase the former Auxerre player next summer for 3 million euros ($4m).

"I am very happy to have joined Olympiakos and I am ready to give my best for the team and the supporters," said Ndinga, who was a personal choice of the Piraeus club's strategic advisor and former France midfielder Christian Karembeu.

The 25-year-old Ndinga played in 27 matches last season as Monaco won the Ligue 2 title but has fallen down the pecking order this summer after the principality club signed Jeremy Toulalan and then Geoffrey Kondogbia.
