Lawyers argued last month before the Conseil de prud'hommes de Paris in a judicial saga involving colossal sums. The court sided with the player amid accusations of betrayal and harassment surrounding the breakdown of his relationship with PSG
Mbappé's lawyers claimed PSG owed him more than €260m ($305m), and PSG was seeking €440m from Mbappé, citing damages and a "loss of opportunity" after he left on a free transfer.
The court's ruling can be appealed and is unlikely to end the dispute.
Mbappé's representatives said the ruling "confirms that commitments must be honored. It restores a simple truth: Even in the professional football industry labor law applies to everyone."
There was no immediate reaction from PSG.
The relationship between the 2018 World Cup winner and the reigning European champion turned bitter when Mbappé decided in 2023 not to extend his contract, which was set to expire in summer 2024.
This deprived the club of a huge transfer fee despite having offered him the most lucrative contract in club history when he signed a new deal in 2022. He was sidelined from a preseason tour and forced to train with fringe players. He missed the opening league game but returned to the lineup for a final season after discussions with the club -- talks that are central to the dispute.
The club accused Mbappé of backing out of an August 2023 agreement that allegedly included a pay reduction should he leave on a free transfer, an arrangement PSG said was meant to protect their financial stability.
PSG claimed that Mbappé hid his decision not to extend his contract for nearly 11 months, from July 2022 to June 2023, preventing the club from arranging a transfer and causing major financial harm. It accused him of violating contractual obligations and the principles of good faith and loyalty.
Mbappé's camp insisted PSG have never produced evidence that the striker agreed to forego any payment. His lawyers claimed the club failed to pay wages and bonuses for April, May, and June 2024.
"Mbappé scrupulously fulfilled his sporting and contractual obligations for seven years and right up to the final day," his advisers said on Tuesday. "He did everything possible to avoid litigation, even going so far as to withdraw a harassment complaint in a spirit of conciliation. In total, he had been seeking payment of his salaries and bonuses for more than 18 months."
PSG rejected all accusations of harassment, highlighting that Mbappé took part in over 94% of matches in 2023-24 and always worked under conditions compliant with the Professional Football Charter.
PSG were seeking a total of €440m in damages, including €180m for the lost opportunity to transfer Mbappé because he left as a free agent after declining a €300m offer from Saudi Pro League club Al Hilal in July 2023.
Mbappé joined Real Madrid in the summer of 2024 on a free transfer after scoring a club-record 256 goals in seven years at PSG, who won the Champions League this year without him.
