Former Manchester United defender Rio Ferdinand says John Stones would be a "lunatic" to leave Everton for Chelsea.
The Englishman believes the 21-year-old should make a move to Old Trafford in order to enjoy regular first-team football in Louis van Gaal's squad.
And that's because he will always be behind John Terry and Gary Cahill in the pecking order at Stamford Bridge.
"If he goes to Man United, he plays every week so that's the right club for him," Ferdinand is quoted as saying by The Guardian.
"If he goes to Chelsea, he's not playing every week.
"He's at that stage of his development where he wants to play every week. If you say to any young footballer to leave a club to sit on the bench, you've got to be a lunatic. You have to be."
