Chelsea chiefs fear they face a major exodus this summer.
The Mirror says there is a growing fear that Eden Hazard and keeper Thibaut Courtois could follow Antonio Conte out of the exit door if last season's title winners club fail to achieve the top four finish that gets them back among the European elite next season.
Boss Conte looks certain to leave Stamford Bridge this summer — even winning the FA Cup, in which they have a quarter-final away to Leicester on Sunday, would not be enough to save him after a disappointing campaign.
Belgium internationals Hazard and Courtois are both likely to be big-money targets for Real Madrid this summer, while French champions-to-be Paris Saint-Germain are watching developments closely.
Hazard has yet to commit himself to a new contract, despite Chelsea being ready to make him the best paid player at the club with a £300,000-a-week deal.
Courtois is potentially an even bigger and more immediate concern as he will enter the final year of his contract this summer. Unless he signs a new deal, the Blues may have to sell.
