From what I’ve read, they’ll be playing as wing backs so 50/50 responsibility for attacking & defending.
Your favourite positions of full back and defensive midfielder look to be ditched with Potter going 3-5-2. This could be a very very difficult season for you; might be worth declaring...
At 18, his got time on his side to develop.
However, the quality of assists in the below showreel suggest that he’d not be spending much time with the U23s should we sign him up.

Potter seems to like working with talented young players that he can mould. I’d be surprised if there are any ‘tried and trusted’ signings at all.
In addition, it’s likely that Bogle would be a wing back. His ‘assists’ column from last year is very very good for a full back.
