England coach Roy Hodgson wants a full-strength squad to compete in next summer's U21 Euros.
Providing they get through a two-legged play-off against Croatia, Gareth Southgate's Young Lions will take part in the eight-team tournament in the Czech Republic next June.
Hodgson said: "I am certain there will be players (there) who will have made a (senior) appearance or will have been with us.
"We are going to say - 'Look, just because you have been with us for a while that doesn't make you a 100% bona fide senior that never plays anywhere else. It just makes you an England player and we are going to use you where we think best'."
