Standard Liege insist defender Oguchi Onyewu is not for sale. The USA international is off contract in June and attracting big interest from Olympique Marseille.

However, Standard chief Pierre Francois insists: "His contract expires in June next year and we can hardly extend it, however the player will not leave in January.

"We know that we're giving up money, but right now the technical issues matter more than the economic."
