Jordan Pickford is facing an uncertain future as Everton's first-choice goalkeeper.
The Daily Star says Carlo Ancelotti is running out of patience with the England international after a number of mistakes this season.
The Italian wants to push for European qualification next season and Pickford could be sold to raise funds for other transfers.
Chelsea are reportedly one of the several teams who would look at the 26-year-old if he became available.
Pickford joined the Toffees from Sunderland in 2017 in a £30m deal.
