Sure, though in some sense it's not that special of a case. An extreme case perhaps, but agents fees and the like are part of normal transfers too.I agree with all that, I was only speaking about true cost of a transfer, haaland is a special case due to the way he set up his contract. Mbappe would be the same
Net spend is a useful look at how a club is navigating the transfer market. But it doesn't correlate with success very well at all, unlike overall player expenditures.
