I did state so. Earning 30m per year, the highest in the world (or at some point was), isn't enough so also demand a massive loyalty bonus that is equal to three seasons worth of salaries. Clubs have to cave in to a demand from a player as great as Messi. I'm all for players getting whatever dollar that can, doesn't mean they're not greedy fecks though.
So is your issue is that player(s) get a massive final pay day for their [assumed] final contract from a club, or is it just the numbers with Messi that you find contentious?
It's simple relativity - he's the best, so he comes with the highest premium there is.
The numbers are eye-watering until you actually consider how much it would cost them to replace him outright whilst remaining as strong as they are with him at the club.
Given the way the market played out this summer, £80m won't even get you one top-end player and that's before wages are factored in, and to replace Messi, you're going to need two or three of those.
