A 20 year old right back, if they were going to make it would have at least had a game or two by now. The fact that he hasn't and hasn't been sold when he has some value is insane.
We (rightfully) complain about the RS doing well in getting young players out the door at top $, but there's a structure in place there where players go out on loan and get game time at clubs that suit them and either get in the shop window or come back to play for the first team.
Our approach to loaning players is ridiculous, I can't think of the last player who went out on loan and came back a better player. We seem to have a large number though who go out and either don't get a game (indicating we don't vet the clubs properly) or regress (again with the vetting and style of play).
If you look at Chelsea/Man City/Liverpool - the whole point of a youth setup is to generate income through player sales and create players for the first team. We do neither.
I don't know why Unsworth hasn't been binned off yet, but this is entirely on him and Brands. The talent is there - we have players from U16 onwards who play representative football, they just seem to hit a wall and lose their way. To my mind this is the biggest failure of the current regime.
