Specially top teams, Unless you're a feeding club like Ajax who produces talent after talent and has no problem selling them, hence creating opportunities for youngsters to step up, then its really hard for a youngster to make his way through the first team.
From top teams the one I have most in mind its Chelsea. I think they're the one's producing the most quality players lately, but most of them make it outside Chelsea. Such as Ake, Guehi, Tammy Abraham, Lamptey, Traore, Livramento, Tomori, etc
Top teams usually have only special talents, Liverpools has only TAA starting, City only Foden, Chelsea Reece James and Mount (until now), Arsenal has Saka and Martinelli (I dont know if he counts as academy or not) we have Rashford. So its pretty even between all the top teams. Its really rare for top teams to have several academy players as starters.
