England U21 boss Stuart Pearce has selected several new names in his squad for next week's friendly against Poland.
Coventry defenders Scott Dann and Daniel Fox and Hull forward Fraizer Campbell, currently on loan from Manchester United, are the three new faces in a squad, while Matt Derbyshire and Michael Johnson return.
The former Manchester City boss revealed he plans to use next Tuesday's clash at Molineux, and a further friendly against Wales in May, to take a look at his fringe players in order to give as many youngsters as possible experience of the international stage.
He said: "The biggest risk would have been not to do this in my eyes.
"As we stand at the moment, we look as if we are in the play-offs so the result of the Portugal game will probably dictate who wins the group.
"My big risk would be to take a team to the finals and maybe having 12 or 13 players that have got real experience and caps behind them. I think that's a dangerous thing to do.
"It would be a massive risk for me not to use this game and probably the Welsh game and put players in and say 'are you good enough for this level or are you not'? because I don't want to be going to a final and trying to find that out."
