If we are buying the finished article how come they need a season to acclimatise prove unsuited to the league ? At least you know most of your U23 side are suited to the league but unless you play them you won't know . Holgate , Davies and Kenny are well capable of covering and in time being first choice .
It has only been Davies that had cemented a place in the team. Others are just covering as you say and as soon as the injured player is fit they are out again.
The other issue, as ever, is experience. Young players can be good enough physically and technically but they dont have the games of an older player. This is what limits a lot of their chances. The fact that Everton have been struggling as a team anyway makes their involvement even less likely.
To be fair we do give more chances than most but the queue of players ahead of the kids is always going to be an issue.
The lad I know isnt so bothered about leaving Everton as he wants and needs games. His chances here would be very limited.
