Iyour first point is very hypothetical, given what’s gone on before, but of course not impossible - however, neither is falling out of favour at Chelsea on that basis.
If memory serves me correct their academy scored lower than ours, which was the highest in the country until City came along.
That might be possible but Declan Rice, Reece James, Mason Mount, Jamal Musiala, Fikayo Tomori, Tammy Abraham, Marc Guehi, Something Livramento, Tariq Lamptey, Nathan Ake, Conor Gallagher, Eddie Nketiah, Rhian Brewster, Dominic Solanke, Levi Colwill and probably forgetting some... sort of speaks for itself imo.
