I am 100% sure that although the signing bonus and transfer money are different expense items in an accounting sense, they are both still taken into account by the FFP. But Real can afford such expenses because its income exceeds expenses, they have not made major purchases for a long time (before Bellingham) and have accumulated a good financial reserve.
In addition, I am sure that Mbape will receive his signing bonus not just once, but as the contract is fulfilled, that is, this payment will be spread over several years.
Because in the end management was important and Madrid was smart in managing their money so that even though there were some players who did come to Madrid but it would not make them inconvenience because Madrod would not dig his own grave just because a player they would not sacrifice the club.
When Mbappe is in the SAMUAD regardless of the bonus or whatever the name is definitely Madrid Sudaj predicts what they have to do so as not to be a problem in the future until it also happens this time because it is impossible for Madrid to give a gap, especially in FFP only for a mbappe because in the end It was not a Madrid style at all that was famous for luxury both from performance and from management who did carry out their duties correctly.
The presence of Mbappe will not affect anything, and FFP will only be a bullshit for Madrid.
