The Eagles attacker is emerging a serious target for the Blues this summer and the west London side have now enquired about the attacker.
Olise has a complicated release clause in his contract, which he signed last summer after Chelsea failed in their attempts to sign him last summer.
Chelsea are now trying to ascertain the accurate details of Olise’s buy-out following their botched move in 2023, Mail Sport reports .
Manchester United are also interested in Olise, but have a limited budget to work with.
Chelsea look to freshen up their front line under new manager Enzo Maresca, but there will be a battle for Olise’s signature after his impressive performances with Crystal Palace, scoring 10 and making 6 assists despite injury struggles.
