Everton have completed a deal for John Stones from Barnsley in a £3m deal.
The 18-year-old right back has signed a five-and-a-half year deal.
The 6ft 2ins player has made 28 appearances for the Tykes, scoring his first goal in a 4-3 League Cup victory over Rochdale in August last year.
He said: "I am very excited to be joining Everton. I've been very impressed with everything I have seen at Finch Farm already. Now the hard work begins."
