Although I would like the youth players to be worth their introduction into the first team, I think more realistically speaking the next season is going to be:
Davies (squad)
Holgate (squad)
Lookman (maybe around 1st team, maybe teddies out of pram and transfer - all depends on him and manager/DoF)
Vlasic (squad or loan in Europe)
Kenny (squad or possible transfer)
DCL (squad)
Dowell (loan or possible transfer - I have an odd suspicion he could end up with the porn barons)
Baningime (squad)
Williams (loan or transfer)
Connolly (squad or transfer)
Robinson (squad or loan)
That's even me, who is an enthusiastic backer of youth players, doubting that you are going to get nine out of a planned squad of 25 being youth players. So on the negative side, some of those I have as squad above could well leave. On the other hand, squad means that they are not automatic first choice but could convince new management to give them a chance over existing players.
(The ones I think have most of a chance are actually Baningime and Connolly. Davies and DCL are existing first team/squad players but could get crowded out as signings are being contemplated in both their positions. Holgate and Kenny are potentially having a battle for Coleman's back-up position and Holgate wins by also being back-up central defender. Out of all those my favourites are Williams and Kenny - unfortunately I don't see either of them making it here long term although I'm sure they will have good professional careers.)
