I guess the question is whether he would benefit more from playing at L1 level ( think Championship might be a step too high at this stage ) or train with the 1st team.
This is what pre-season will decide. He will get preseason with the first team and that can show what level he needs loaning too.
It’s quite hard to see how good he is as that level is so poor. We had plenty of young lads who were doing what he’s done, but they were doing it in the old reserves which is levels higher than he’s playing at, and they ended up struggling with the step up.
Unfortunately we have a lot of clowns who seem to think he should be starting now, that is a sure fire way to ruin him.
