Stones, 20, broke into the Everton first team last season and was rewarded with an England call-up by national coach Roy Hodgson, making two friendly appearances prior to the World Cup.

He has now followed team-mates Ross Barkley -- a fellow fledgling England international -- and Irish right-back Seamus Coleman in agreeing a new deal at Goodison Park.

"I am over the moon," Stones told the Everton website.

"It's just been such a great last season and to get pen to paper on a new deal is a dream come true.

"The last 12 months have been so enjoyable thanks to the faith that the manager (Roberto Martinez) has shown in me and all the players.

"What we achieved was unbelievable. It was a very memorable season and hopefully there's more to come."

Stones joined Everton from Barnsley in January 2013. He made 26 appearances last season as Everton finished fifth in the Premier League.

"It is an important signing for the club and a really good reward for a young footballer with a fantastic future," said Everton manager Martinez.

"He had an excellent season in 2013-14 and it's really good news all round. It is very important that we continue to let our youngsters continue to develop into bigger roles."
