Les Girondins coach Laurent Blanc has declared his interest in the France international, whose season has been disrupted by knee injuries.

Silvestre's contract at United runs until the summer of 2009, but the former Rennes player is not discounting a return to his native country if the offer is good enough and told a press conference: "It isn't impossible."

He added: "Bordeaux is a club which is close to my heart. When I was little, I followed their exploits in Europe. Moreover, I have family in the Gironde region.

"But each player has to be satisfied in a sporting sense as well as financially.

"There are no gifts handed out here. I am not a good Samaritan."

Silvestre, who has also played for Internazionale, missed most of United's latest title-winning campaign with a knee injury he suffered in September.

He returned towards the end of the season but he is unlikely to make France's squad for next month's European Championships in Austria and Switzerland.
