Moore has had (nearly) a full season at Rangers now, so yes there is a case to bring him back next season but only if he's guaranteed minutes and like it or not, he's still got more experienced players ahead of him in the squad.
As I said, a lot depends on De Zerbi but there's a good chance that Mickey will still have Madders, Xavi, Tel, Odobert and Kulu ahead of him in his favoured positions and if that is the case, I'd rather he was out playing every week than getting a handful of minutes here and there.
There's no rush to force him into the squad and at his age, continued development is the most important thing, which only comes with competitive, constant game time.
