Chelsea are interested in Lille star Eden Hazard and have reportedly made an enquiry to the Ligue 1 club about the availability of the promising winger. However, Lille's vice general director Frederic Pacquet has warned the Blues not to approach star man behind their backs, and intends to keep hold of the 20-year-old Belgium international.
Pacquet, speaking to French sports paper L'Equipe said: "If Chelsea directly contacted Eden, we would take offence at it.
"That is not the right custom.
"No one is up for sale - that is very clear. We want to keep as many players as possible."
