No, I am not disputing that it makes sense for Madrid to get Mbappe, I am saying it makes no sense for Madrid to pay upward 200m to get him NOW when they can get him for free next summer. Smaller financial package? Sure Madrid will avoid a hefty signing bonus, but I'd imagine it will be a lot less than 200m. Getting on good terms with PSG and Qatar might be important (I don't know, the two are already having a chilled relationship due to ESL), but it certainly is not worth 200m plus.
I am claiming that it makes ton of sense paying cash now, instead of dealing with Mbappe being free agent with ton of leverage which would definitely go over 100M just in terms of signing bonus let alone other factors such as wages, question of image rights and other bonuses. Hence, even if it goes over 200M, who cares?
PSG gets cash. Mbappe gets his dream club. While Madrid does not go to war with PSG and instead gets a post CR7 / Messi generational player to present at New Bernabeu.
