Chelsea coach Jose Mourinho has said he has helped Eden Hazard to improve his game so much that he is now an important member of the squad, and added that his club would not sell him for any amount.
Reports in France claim Paris Saint-Germain are contemplating making a bid for Hazard this month.
Hazard's talent has never been in doubt but in the early stages of this season it was not certain whether he and Mourinho would thrive together, as the midfielder's inconsistency and occasional defensive frailty frustrated the manager.
Mourinho said he convinced the 23-year-old to focus more and become a complete player, The Guardian reports.
He said Hazard has made progress in everything and has become a good professional.
Chelsea will go top of the Premier League, at least temporarily, if they win at Hull City on Saturday.
