Which is why we managed to buy Pogba and Lukaku the way we did? City and PSG are p*ssing money around, but what exactly did they win apart from diddly-squat? How many of their players were in the BdO shortlist? The Mbappe deal aside (reminiscent of Ronaldo in some ways with his love for Madrid), how many top players move where we're not linked? Neymar's move is indeed an exception; if PSG do indeed pay 220 Mn for him, that'd be more than a third of their revenues (520 Mn of so). That's not normal and would not be sensible for any club that actually runs like a business. Throw in the wages mentioned and it's downright stupid.
Add also the factor that PSG (and City) have a long way to go in terms of market penetration (fan numbers globally) and genuine endorsement maximization. Overspending in the hope of catching up there could be viable for them. For us, the math is very different.
Now, coming back to reality, even if you accept that City and PSG could outspend us, that still leaves us ahead of the vast majority of clubs in the world. No club barring these two can realistically expect anything but being blown away in a straight financial fight. And I'd wager that there are more world-class players available than they can buy - and that a decent number of those that we want may even prefer us to them.
Finally, he's a CEO of a massive brand. What do you expect him to say? "Yeah, we're the richest and biggest, but well, we're not quite the top of the world, because these plaything-clubs can actually outgun us whenever needed"?
