UNITED could test Lyon's resolve to hang onto £30m-rated striker Karim Benzema after the deposed French champions left the door ajar for potential suitors.

Although Lyon have insisted they want to keep the French international hitman, their chairman Jean-Michel Aulas has said Benzema is "not untransferable".

The 21-year-old Benzema has stuck by his desire to remain in France until he is ready for the big stage and says he won't be asking for a transfer.

But Lyon finally relinquished their French title after seven years as champions to Laurent Blanc's Bordeaux last month and will now have to qualify for the Champions League next season.

And, if a top European club coming calling, he may be tempted by the lure of guaranteed Champions League football.

He said: "If there is a huge offer and the chairman tells me I have to go, I would probably leave.

"But I will not go and see him to ask to leave.

"I am 21 and have time to play for another club.

"The clubs are going to carry on calling, everyone is looking for forwards. But I am fine at Lyon."

However reluctant he is to quit his hometown club it is clear Lyon would be interested in cashing in on a player they have nurtured.

"He said he wants to stay. I don't want to sell. So he is here at 99 per cent," says Aulas.

"However, Kaka should have not left Milan and he will join Real Madrid. We have entered spiral madness. Anyway, I am relaxed. I won't say Karim is untransferable."

United boss Sir Alex Ferguson has long been an admirer of Benzema's goal talent and is set to be looking for forwards with the likely departure of Carlos Tevez and the uncertainty again over Cristiano Ronaldo's immediate future.
