I doubt that will ever happen formally, but there's no reason why it couldn't happen informally? I mean take Tranmere for instance. The club could easily strike up a partnership with them whereby Tranmere benefit from our coaching expertise (The Everton Way), maybe even use our facilities now and then.
That would ensure that Tranmere play in a way that educates our kids in the right way. We'd then make sure as many of our youngsters go there on loan as possible. Likewise, if Tranmere ever get any good kids on their books, they'd have a good route to the Premier League through us.
Could even use this for coach development as well, sending people doing their coaching qualifications to our partner clubs to get experience in professional environments.
Do that with a couple of clubs and you'd have as good as a B team in the lower leagues.
