Lille admit they will find it increasingly difficult to keep hold of Eden Hazard if he continues to improve.
The 19-year-old winger has become an integral member of the Ligue 1 side's first XI since breaking onto the scene in 2007 and starred in Sunday's success over Monaco to further enhance his growing reputation.
Hazard scored against Liverpool in the Europa League last season and has been linked with a January transfer switch to Merseyside with Roy Hodgson a keen admirer of the teenager's talents.
Manchester United are also said to be monitoring the Belgium international's movements and Arsenal are another Premier League team to have expressed an interest in the mercurial flyer.
President Michel Seydoux insists the warning signals that they could lose Hazard are already ringing, but Les Dogues are not concerned with the midfielder's future at the present time.
"For now, we take pleasure in watching him play, we take advantage," Seydoux told La Voix du Nord after Lille went top of the French table at the weekend. "But you know, the sirens did not start this morning.
"On Sunday, he was incredible. He has warmed us in this cold weather.
"We will not hide - it seems obvious that there will be requests for such a talent. But the player has already understood that he works well here, and that there are people who help him reach his level."
Seydoux then offered a cryptic message of a potential switch to England adding: "A nugget is good, but in the middle of the desert it is useless."
