England U21 coach Gareth Southgate has heaped praise on Everton defender John Stones.
Stones is on stand-by for the World Cup.
"John has emerged from our programme of the Under 20s World Cup last year and been outstanding for us this season," said Southgate. "His composure on the ball is fantastic, we're looking for defenders to play out.
'His experience at full back probably helped that. Like any centre back he will have to learn the defensive positioning but nothing fazes him. Raheem and Luke we have had less of. They are in their first team anyway and it's been a different process.
"But the one that most pleased me was John. It is probably one that for club and country worked really nicely. The relationship we had with Roberto (Martinez) and Graeme (Jones) hopefully played a part in that.
"In the end it is down to the player and his fantastic attitude and his desire to keep learning. I have spoken with him and I expect he will go on to Miami with the seniors and then see what happens. It is a pleasure to work with boys like him."
