Paris Saint-Germain have been linked with a move for Thibaut Courtois, while Eden Hazard remains a target for the French giants.
Chelsea, who were dumped out of the Champions League by PSG earlier this week, could face a battle to keep hold of some of their players following a disappointing campaign.
The Blues were knocked out of the FA Cup by Everton on Saturday and a top-four finish looks highly unlikely as they trail fourth-placed Manchester City by 11 points.
Chelsea could well miss out on European football altogether and PSG hope to use that to their advantage this summer.
The Parisian outfit have long been linked with Hazard and now keeper Courtois has emerged as a target, reports ESPN.
Chelsea may be prepared to cash in on Hazard after a lacklustre campaign but they will be eager to keep hold of Courtois, who has impressed despite his side’s struggles.
Previously a price tag of around Â£80million has been mooted for Hazard and it may take a similar bid to force the Stamford Bridge side to listen to offers for their goalkeeper.
