You are adding the bonus to the maximum he can get again.
Including bonuses and winning everything the most he gets for a season is 138m.
Ok, but knowing Messi, his maximum was 138, but a fixed amount was probably at least 100m, right?
There is no way that Messi plays for less even if don't win anything.
And then I guess that majority of bonuses are easy to achieve, like in Dembele's and Cou's transfer, where we needed to qualify for a CL and similar.
Ok, there is winning a CL bonus, but also there are bonuses for playing more than 60% of matches where in his case even 45 minutes counts as a match played.
So, I am just guessing, but out of 138m, he will get probably 110-120-125m this season with a fixed base + easily achieved silly bonuses.
So, let's say 115 or 120m plus 66m loyalty bonus for leaving us = 181 or 186m to be paid this season.
So, even if spend "only" 180-185m for Messi this season, that is still around Halaand's price.
The most expensive transfers in a history were Neymar 220, Mbappe 180, Cou 165, Dembele 145, Felix 130, Griezz 120, Cr7 120, Hazard 115.
So, literally, we have lost Halaand/Felix or Salah just for keeping Messi for 1 year.
Was it worth it?
Hell no.
A guy needed 80 shots in the first part of a season to score 1 goal from an open play.
Now imagine some election's candidates who want to keep Messi in the next season.
120m this season and 120m in the next plus 66m for leaving is =306m for 2 seasons.
That is almost Halaand + Felix.
Would you guys rather have BOTH Halaand and Felix or a 35 years old Messi?
