Moore is probably a decent player who, for whatever reason, didn’t fit the systems that Adams and Lowe wanted to play. He’s still young and so has time to prove himself capable of being a pro footballer.
Maybe a year out of the match day squad wondering if you will have any kind of career really does give you a massive wake up call and the incentive to grasp any opportunity.....which it looks like he has!
Good luck to him.
Probably thought he had it made being at Arsenal.....now realises life can be tough
