Re-read what you've just written and tell me any part of it that would provide any sort of platform for a young pro to try and establish themselves at first team level. The entire club is toxic. He'd get 20 mins at a push, in a side bereft of confidence and lost for how to score.
Or you send him on loan, where he's becoming a central part of Cardiff's attacking line, getting consistent games and starting to produce output, whilst gaining confidence in his ability.
