It's so easy to use City's name as an agent because the assumption is always we have loads of money and will give massive contracts out.
What irks me a little bit is that some of the most respected transfer 'gurus' have no problem doing an agent's bidding for them. Castles is another one (like Ornstein) who keeps his relationships alive by happily peddling whatever they want him to.
Hence the Athletic glossed over Haaland, and didn't mention Daka or Nunez. Instead focussing on players in the middle of contract renewals. Very transparent.
