The lack of context makes it cherry picking
Their backups cost most than most teams starters
, Rodri was the most expensive DM ever at the time and so was Ederson for GK's.
Main difference is also when they buy, they can afford to take their time with them or replace guys immediately if it doesn't work out while a lot of these other clubs are stuck for years with the same guys.
Even Grealish was able to be eased in slowly despite being the most expensive PL player ever, that's not the case anywhere else.
What he's saying sounds nice but they have a massive advantage in terms of recruitment when you actually look into it further. Only 1 other club in the world could've afforded Haalands wages + 3rd party/agent fees (about 200M) even with his low release clause at BVB, that's P$G.
