The Frenchman has been heavily linked with a move away from Selhurst Park this summer, with Newcastle, Bayern Munich, Arsenal, Liverpool and both Manchester clubs cited as being among his suitors.
Olise has a ‘complicated’ release clause in his contract with the Eagles, but Chelsea remain determined to strike an agreement to lure the versatile winger to Stamford Bridge – having failed to persuade the former Reading star to join the club just 12 months ago.
The Blues have already been in contact with Palace to request permission to speak with Olise’s entourage, though it remains to be seen whether Maresca’s project is more of an exciting proposition than proposals elsewhere.
