Everton will allegedly insist on receiving £70m if any club shows an interest in Moise Kean during the summer transfer window.
The forward endured a disappointing first year at Goodison Park, resulting in the Toffees being happy to loan the youngster out to Paris Saint-Germain for the 2020-21 campaign.
The 20-year-old has taken his opportunity to impress, the latest of his 14 goals this season coming against Barcelona in the Champions League in midweek.
Club officials are determined to make a considerable profit on the Italian, who has contributed just four strikes for Everton since his £27.5m switch from Juventus.
Kean still has over three years remaining on his contract at the Merseyside outfit.
