Elizabeth France.. wife of David France.. an Everton histrorian. Toffeeweb did their annual interview with her.. excellent read. An excerpt of the point:
Despite our success with the Under 23 team, our young players struggle to progress – perhaps the Premier League standard is too high and our patience too short. Tom Davies, Dom Calvert-Lewin and Jonjoe Kenny have yet to fully embrace their opportunities. So much potential, so few results. Possibly, we have unreal expectations. After all, we develop only one youngster of real merit every couple of seasons. The past 20 years or so have produced Jeffers, Anichebe, Branch, Ball, Dunne, Hibbert, Osman, Rodwell, Barkley and, of course, Our Wayne. How many of them – in their prime - would get into our first-team today? I hope I’m not alone in thinking that youth teams should not be judged by the trophies they win, but by how many players make it to the first-team or are sold for a handsome profit. Which makes me fret about Lewis Gibson whose contract expires in June 2020.
