John Stones not for sale - Roberto Martinez

Everton boss Roberto Martinez has insisted that defender John Stones is not for sale at any price this summer.

The England international has attracted interest from the likes of Chelsea and Manchester United in recent weeks.

However, Martinez has stated that the 21-year-old will remain at Goodison Park beyond the summer, as the club have no interest in cashing in on his services.

"I have said before the player is not for sale and that is the end of it.Our situation has been very clear from the beginning. We are not a selling club who will lose our best performers." he told Sky Sports News.

"He is very important player for us and we are looking forward to seeing the best of John over the next few seasons, not just the next few weeks."

Stones joined the Merseyside outfit from Barnsley in 2013.
