Who are these emerging young players? Edwards is the only one currently good enough and definitely an Albion player next season. Add Field if we're aspiring to mid table Championship (though he's unlikely to be suited to a high energy pressing style anyway).
Harper, Field, Edwards. Those three should be integrated into the first team.
Leko no not good enough, Tulloch the same. Morgan Rogers maybe in a years time. Louie Barry has possibly more potential than any of them (Barcelona allegedly watching him) but he's only fifteen so realistically two or three years away at least depending on his physical growth.
The likes of OShea, Fitzwater, Ferguson and Wilson I think will struggle to make the grade.
Just my opinion at this stage.
