Being a L2 backup but then playing 22 Championship games in one season is going to pique interest in him for sure.
I'm sure it will get his name mentioned in conversations but that doesn't necessarily result in offers for his services, even if he is available for free. Clubs will look at his previous record and see he's hardly played before that, be aware he came in due to injury to our main keeper and that, although he did keep the shirt ahead of the emergency signing of Camp, during that time he did also make a fair few mistakes, especially towards the end before he was dropped again.
I could be wrong and someone would approach the club about his availability. I'm just not entirely convinced it'd happen.
