England manager Roy Hodgson has named a 23-man squad for the World Cup with seven players on stand-by.
A youthful squad has been chosen by Hodgson, with eight players confirmed under the age of 24.
"These youngsters have imposed themselves upon me and my thinking because they've been so effective and successful for their clubs," Hodgson was quoted by Sky Sports.
"A lot has changed since we qualified back in October and you can't ignore what they've have been doing on a week-to-week basis. Some of them may have been deemed fringe players last year but not any more."
Experienced players have also been selected, including 35-year-old Chelsea midfielder Frank Lampard.
Hodgson said: "Frank is still a very important part of our set-up. His leadership qualities and his ability means he fully deserves his selection."
Jon Flanagan of Liverpool and Everton's John Stones - who are both yet to win a cap for England - are surprise picks by Hodgson that have been put on the stand-by list.
England will play a friendly against Peru at Wembley on May 30. The final squad will then go to Florida where they will play friendlies against Ecuador and Honduras on June 4 and 7.
England's opening game at the World Cup will be against Italy in Manaus on June 14.
