John Stones has told Everton he wants to leave the club to join Manchester City this summer, the Daily Mail is reporting.
Everton are believed to want £50million for the England international which would make him Britain’s most-expensive defender.
Stones is wanted by City boss Pep Guardiola and has informed the Toffees of his wish to move to the Etihad.
The 22-year-old centre back was the subject of interest from Chelsea last summer but the west London side failed to convince Everton into selling one of their prized assets despite tabling a £38m bid.
Stones, who moved to Goodison Park from Barnsley in January 2013 for a fee believed to be in the region of £3m, did not play a minute of England’s failed Euro 2016 campaign.
Everton boss Ronald Koeman has his eye on a number of defensive reinforcements with Scott Dann and Porto centre back Bruno Martins Indi among the names being considered.
Koeman made his first signing as Everton boss last week when he brought in compatriot Maarten Stekelenburg from Fulham.
He has been tipped to raid former side Southampton for striker Graziano Pelle but faces competition from Chelsea.
