There is every chance that he will be used next season, maybe it is the perfect chance, division and timing for him to get in the squad and force himself in.
I don't buy into Warnock not playing him due to his age. If he feels he can trust the lad to take care of the responsibilities put on a player given the game plan and position he takes on the field then he will play him.
Warnock is all about responsibility on the pitch over imagination or flair. If the lad can perform the job asked of him then he will play, that is first and foremost. If he is capable of doing that then he will have the chance to showcase the more enterprising assets to his game.
