I get Ings as he might be a late developer who maybe has something but obviously not going to be risked for the full team. But given that we're almost guaranteed to qualify, why not give those who are 17/18/19 a go? Unless we have an amazing full team, don't like seeing players of 20,21,22 etc...
But they've clearly bought in quite a few who are within the right age group, could they not have bought in a few more and not bothered with Ince, Zaha, Lingard and Ings? Doesn't make sense to me.
