I'm not sure why you're so convinced that we'll be able to "win anything with kids". Nowadays, clubs buy success. Successful clubs buy ready made players. Barely any sides rely on their academies for their best players. Even the likes of Saints sell them pretty early and still spend big amounts...
I don't think Bloom is that naive, as if he's going "I can't believe they still want more money at this club!"
While not complaining, it is very odd that we seemed determined to spend bazillions on the ground, the academy and everything else but not on the one place which will actually get us...
