People comparing this to Chelsea is interesting. Yes, it's always romantic and a proud moment when you have a few academy players come into the first team if not start. But if you look at who has won the league recently, those teams don't have many academy players playing a huge part in their success. It's usually just 1 or 2 at most.
Chelsea might have won CL last year or whatever, but they haven't challenge for the league since Conte(?) and are in a boat where their youth players a nice, but just not good enough to get them challenging at the very top year over year.
Tomori, Abraham, Livramento...all sold. Mount is a nice player. Gallagher is lost a bit in the shuffle now. RLC took years to establish himself as a reliable first team player, but he's also not good enough to where Chelsea wants to be considering their spend and expectations as a cup team. Reese James is their best youth player to first team player.
Where as United have allowed their youth players, whoever could make the grade, be part of the first team from the off such as Marcus, McTominay, former 11, Elanga now, etc.
Iqbal is what, 18/19, so he has plenty of time to develop and truly make the jump in the coming years. Same with Galbraith. They may not mature into a good enough first team player right now, but over the course of their career, they might and that's okay if they aren't good enough for United now or within the next couple of years. It's not easy.
