The 20-year-old has long been linked with a move away from Lille and has impressed for the club in Ligue 1 this season.
“He has shown right from the start of this campaign that he can play for any of the big clubs, including Real Madrid,” Bico told Marca.
“It is clear to see that he has matured a lot recently and he looks ready to take the next step in his career.
“It’s true that Real Madrid have been watching him for quite a while. I don’t think that [Zinedine] Zidane’s presence will necessarily be the decisive factor. Zidane has always praised him but that, on its own, will not be sufficient.”
Hazard’s current contract with Lille is set to expire in the summer of 2015.
