Arsenal, Real Madrid and Manchester United have been put on red alert after Lille coach Rudi Garcia revealed that Eden Hazard is set to leave the club next summer.
Hazard, 20, is rated one of the best young talents in Europe and has been attracting interest from a number of top clubs.
Reports last week suggested that Real Madrid had already agreed a five-year deal to sign the Belgian superstar but he is still keeping his options open.
Lille will only consider an offer in the region of £35m and Garcia expects him to make a big-money move at the end of the season.
Garcia said: "We're thinking about it, of course. But it is still a little early at the moment. It would be very hard to replace a player of Eden's calibre. We'll see what we can do, but for the moment we are making the most of his presence here."
