Interesting he is commenting on Liverpool, Liverpool/Klopp are bringing through younger players like TAA/Gomez etc, but he doesn't comment on Angel Gomes who is reluctant to sign a new deal with Utd as he has hardly played, so might be off to Dortmund, he won the U20 World Cup as well.
There's so much pressure on managers now for results, it's hard for them to risk young players, a few losses and the fans are on their back and the chairman gets twitchy. I think the only way this will get resolved is if the PL bring in a rule, where say 3 U21 players have to be in the matchday squad, then the price for young players will go even higher, but they will probably just sit on the bench.
It's the old saying, if there good enough they will play, if we had a Gerrard/Fowler/Owen coming through now, they'd be getting games as they were that good at 17-18.
