Well, at the time he was 23 and he is still 23.
Since tournaments are every two years no player can be 24 and play for the u21s. 23 is the maximum age.
Ings is not in the squad as he is no longer eligible.
I don't think there are any over 21s in the squad since the first qualifier isn't until September.
They are only allowed players over 21 if they were 21 at a certain time e.g. when qualification began. I don't know the exact rules/timings but I seem to remember at a tournament a few years ago a couple of players who were 23 were still eligible.
That's for the Development League, not...
