TBH, if he was good enough for the England squad he would have been called up by now (being our most capped U21 player ever).
I just dont think he is going to get a chance under Mr Constipated because of the likes of Young & Downing.
IMO, he has got to be worth a go against Estonia, to see how he fares at that level.
It can only do NUFC a favour in the long term.
