Chelsea have joined the race for Everton defender John Stones but will face a difficult task prising him away.

Arsenal also have an interest in the 19-year-old, who is being tipped as an outsider for Roy Hodgson's World Cup training squad.
Stones was bought from Barnsley by David Moyes in January 2013 for a £3million fee, heading off interest from then-Wigan manager Roberto Martinez and Sir Alex Ferguson at Manchester United.

Although he was playing as a right back, Moyes and Martinez recognised Stones would become a centre back and he is showing how in his performances of late.

Arsenal have watched the England U21 defender closely and like his ability to bring the ball out of defence which has come to the fore this season.
