If you think about the contract as a whole it is not too much money. It will be about 160 million for 6 years if its true that his base salary rises by 2 million per year. It will be below 200 million for 6 years of the best player in the world.
For comparison, Liverpool will pay around €250 million for Wirtz for five years (including the transfer fee), assuming a gross salary of €24 million per year. And Lamin is much better than Wirtz, with much higher marketing potential. Great from Deco. Another comparison: Messi earned €138 million gross per year between 2017 and 2021. That was a disaster.
