Oh it is hurting their development.Poch's dislike of loaning out players could be hurting their development. Townsend, Kane, Rose all broke into the first team after having decent loan periods at other Premier League clubs. Pritchard did excellent at Brentford; but it seems the championship was his level, and our coaches spotted that.
To follow up on your point. If we have them out on loan getting games it will be much easier to judge were their level is.
KWP has been actively derailed by not going on loan years ago. Regular minutes is so important at that age.
