I really hate to end up defending Miguel fuckjng Delaney of all people but that list does show one thing very clearly, which is that PSGs Neymar purchase massively inflated the transfer market.
Neymar and Mbappe speak for themselves, Coutinho and Dembele were Barcelona panic spending and Griezmann was a continuation of that. Joao Felix was Atleti spending that money and the reason an 18 year old with 1 good year went for 120m was because people wanted the next Mbappe.
Van Dijk and Alisson both went for their world record fees because Barcelona paid so much for Coutinho and Maguire cost 80m because of VVD resetting the value of centre backs.
So I think he is absolutely right to say PSGs 2018 inflated the transfer market considerably.
Now the thing you've taken offence to is that he said City could compete.....but that's not really wrong. City haven't chosen to compete but we could have. A lot of the transfers involving other clubs (liverpool, atletico) are really them spending PSGs initial 400m they dumped into the market.
We have it from decent sources that City would have spent the money on Mbappe and we tried to get Messi in 2017 which would have been a world record fee.
City haven't competed with the top 10 transfer fees, but that's different to jot being able to. We are able to and it's only a matter of time before we make a top 3 or top 5 transfer IMO.
