Chelsea hope their offer to make Eden Hazard the highest paid player in the club's history will finally fend off interest from Real Madrid.
Blues head coach Maurizio Sarri confirmed on Tuesday said that there is an offer on the table for the Belgium star to sign and it is now only up to him to complete the deal.
Reports emerged in Spain on Wednesday claiming Real Madrid have ramped up their efforts to tempt Hazard away from Stamford Bridge, with his contract moving into its final 18 months in the New Year.
Chelsea have made Hazard a huge offer to be the club's highest earner and they are not commenting on reports his wages could rise towards the £300,000-per-week mark.
