Le Parisien revealed information about Mbappe's contract
According to the French tabloid Le Parisien, Kylian Mbappe is likely to have the largest contract in football last May.

In the contract, Mbappe agreed to play for PSG for two more seasons with an additional -optional- year.
However, the small letters, and the astronomical figures made Mbappe's contract, is the highest sports deal ever signed.
Mbappe's highest contract ever

If Kylian Mbappe decides to fulfill his current contract, which expires in 2025, the French attacking player will get a total of 630 million Euros.

The contract is divided into three parts:

Mbappe's wage: 72 million Euros per season
Signing Bonus: 180 million Euros divided into three payments
Loyalty Bonus: If Mbappe stays in 2023 in PSG he will get 70 million Euros extra, 80 million more if he stays in 2024, and additional 90 million Euros if he stays until 2025.

Mbappe's contract compared to Messi's deal

In 2017, Lionel Messi renewed his contract with Barcelona and secured $138 million per season. Barcelona used similar clauses to pay Messi more than $550 million.

FC Barcelona paid Messi through a renewal clause and a loyalty clause. It was the same method used by PSG with Mbappe. Nevertheless, the Frenchman's contract surpasses Messi's by more than $100 million.

Mbappe and PSG signed the largest contract in football if he doesn't leave the French capital city.

Neymar secured $267 million over six years until 2023. Below him, other mega-contracts were Cristiano Ronaldo's with Juventus, Gareth Bale's with Real Madrid in 2016, and Pogba's when he returned to Manchester United in the summer of 2016.
