City's academy was in danger of having its status downgraded to a centre of excellence over the last 12 months, but manager Coleman believes it is in good shape to safeguard its future after providing several teenagers for first-team consideration this season.
Defenders Curtis Wynter and Jermaine Grandison, central midfielder Adam Walker and winger Ashley Cain have been picked out as ones to watch, and could get first-team run-outs before the end of the season.
"What has struck me about the kids we have seen this year is that, on top of the obvious ability, is the way they have come and conducted themselves has been terrific - and that is down to Gregor Rioch," Coleman told the Coventry Telegraph.
"They have not been in awe of it and have coped with it very well and they are gentlemen, proper gentlemen who have been brought up the right way, and
that has impressed me.
"Adam (Walker) and Curtis (Wynter) have made their debuts this season and and we have got Ashley (Cain), who is going to come in with Jermaine (Grandison) and we will see how they go in the next 12 months."
