Meatwad this is one of those nature vs nurture arguments that casts Edu and Arteta as complete bystanders.
You will recall that when our kids were breaking through that Chelsea had possibly the most heralded academy in Europe. Lampard was brought in as coach during the transfer ban to introduce heralded academy players including Mount, Gilmour, James, Guehi, Lamptey, Broja. He also had CHO, RLC and Abraham at his disposal. Of that group, only James remains. The rest have since been turned over - a compete dissolution of one of the best academy classes in recent memory in England. That’s incredibly bad management.
It’s not just about the luck of having good players. You need to integrate and develop them. We’ve done that.
