Frank Fielding - England Number 1?

With Frank Fielding preparing for the U21 European Championships with England do you think he could one day become England's number 1?
The 23 year old goalkeeper has already had a 1st team call up in 2010 against Hungary and is now securing his number 1 spot for the U21 team. His two loan spells this season in which he impressed a lot of fans earn't him a contract at Derby to the relief of a lot of supporters as a lot of his performances were outstanding.                             
With Ben Foster and Paul Robinson retiring from international duty to concentrate on their club duty's is this the chance for Fielding to really impress during this summer? I believe it is, despite Joe Hart having the England number 1 shirt could Fielding mount a challenge for 2nd or even 3rd choice goalkeeper? Only time will tell but if the current England goalkeepers carry on dropping out like fly's you never know what could happen.
