United will turn the corner when they stop converting elite talents (Sancho, Rashford et al.) into midtable misfits and stop paying elite fees for midtable talents.
Check out the Transfermarkt market value analysis of our squad versus theirs (always debatable, but indicative in aggregate):

It's obviously a bit rough (this tabulation lets us off easy for what we paid for Havertz, Vieira, White, Zinchenko among others), but there's been an obscene amount of value appreciation in our squad due to the conditions we've been creating, from Hale End through to the first XI.
United: Antony, Onana, Højlund, Zirkzee, Mount, Maguire … they've been recruiting like absolute idiots for pretty much a decade. I'm not even counting bizarre decisions like signing Casemiro for £60m at the age of 30.
