Mbappe received a big bonus from "Real" – what is the reason?

In recent days, Kylian Mbappe has been in high spirits. According to El Nacional, a large sum of money has been deposited into the French striker's bank account.
According to the source, the management of "Real" Madrid paid him a bonus of 117 million euros for attracting Mbappe as a free agent. This amount is given as an additional reward, apart from his annual salary.
Despite the PSG club making every effort to retain the striker, the 25-year-old footballer decided to leave Paris in the summer and join "Real".
Since joining "Real", Mbappe has played in 39 matches across all competitions, scoring 27 goals and providing 4 assists.
