Chelsea, Newcastle United and Bayern Munich have all contacted Crystal Palace to register their interest in signing Michael Olise.
Palace will only entertain offers of £60m or more for the 22-year-old winger.
Olise has a release clause worth in the region of £60m and any deal will be complex, with percentages due to his former club Reading, Olise himself and Palace.
Chelsea unsuccessfully attempted to sign him for a fee in the region of £35m last summer, thinking they had activated his release clause.
He joined Palace from Reading in 2021 but was in the Blues youth system before leaving aged 14.
