Everton have told Crystal Palace they are prepared to pay £60 million plus striker Cenk Tosun for Wilfired Zaha, but fear they could miss out to Chelsea.

Telegraph Sport understands that Chelsea are weighing up a bid for Zaha that would take him to Stamford Bridge once the club have served their transfer ban.

Chelsea are currently serving their two-window ban and cannot sign players this summer. They have lodged an appeal to the Court of Arbitration for Sport, but the fear remains they will also be prevented from making any new signings in January.

That may suit Palace, as it would most likely allow Zaha to spend the coming season at Selhurst Park and would also improve their chances of signing Chelsea striker Michy Batshuayi, who spent last season on loan with the Eagles.

Chelsea are yet to make any firm move for 26-year-old Zaha, but the playersis thought to be aware of their potential interest in setting up a transfer for when their ban ends.
