It was probably best to get this game out of the way and give HH more of a view of what players he has, and the shapes they take up.England are ranked 4th in the world, Ireland 59th. 4th ranked Premier league team last season was Aston Villa, 59th was Bristol Rovers. Thats the gulf in class and won't change overnight.
Great win for the u21s though.
The real benchmark will come against Greece and Finland and they need to be better in terms of organisations, tactics for those games.
