It's hard because we don't know the full story. The manager clearly gives our youth players opportunity. After that it may be how they take that opportunity, where he thinks their heads are at at dealing with the pressure and when to give them that opportunity again or to send them out on loan for another stint. Everybody develops differently I guess, both physically and mentally.
It may be not a question of footballing ability right now but the ability to trust a youngster to perform under the lights and on the training ground at this level right now in his development.
