I kind of mentioned this the other day but isn't it a bit early to say you've not paid over the odds (I'm not saying you have btw) on x, y or z? You've gave PSG their money back on a player that flopped for them and paid a fee (and contract) for Yoro that other interested clubs wouldn't. Whether what you've paid is good or bad value will become clear over time but as manic hints at it seems because it's not the Glazers you're automatically saying it's great.
Regarding sales, I really don't see it. Selling players in isolation isn't a challenge (you sold players before), it's selling the ones you want or need to that's the challenge and or getting good fees for those that do leave. Other than Sancho Utd haven't really moved on anybody you'd say they really needed to move on* and the reported future fee of £20m odd isn't a good deal (that's before any possible pay-off to Sancho). And the fees for the easier sales? You hardly cashed in.
*As you say that's not easy given their contracts.
