Kylian Mbappe's PSG future risks becoming a major transfer saga yet again after his contract only runs until 2024 instead of 2025 as was originally thought, according to reports.

The French star signed a new jaw-dropping £650,000-a-week contract with the Parisian club in May, after prolonged questions surrounding his future dominated the headlines last season.

Upon signing the new deal, Mbappe, who snubbed Real Madrid in the process, announced he had signed a three-year-contract and proudly wore a shirt at the Parc des Princes, with 'Mbappe 2025' on the back, while possing with club president Nasser Al-Khelaifi.

Kylian Mbappe's deal at PSG only runs for an initial two years, with a third year at his discretion

However, according to L'Equipe, the contract Mbappe signed is actually only for two years, with the third year an optional extension at the hands of the French international. 

This means that at the end of this season, the forward will enter the final 12 months of his deal, and PSG will again be in the position of deciding whether to try to extend his contract or sell him, to avoid losing him for free at the end of his contract.

This was the case in the summer of 2021 when Real Madrid had made their interest in Mbappe clear when they submitted a final bid of £154million for the Ligue 1 star, in an attempt to pry him away from Paris.

Though the club rejected the proposal, it was widely anticipated that the French star would join Carlo Ancelotti's side a year later before he sensationally penned a new deal at PSG.

As part of the extension to his contract, it was also reported that Mbappe would have 'complete control' of the club's sporting project. 

Ahead of PSG's Champions League win against Juventus last week, Mbappe remained coy when asked about how things have been going since his extension.

He said: 'This is neither the place nor the time and I am not the best person to answer this question. We are here to talk about a Champions League match.' 

Mbappe has started the season in sensational form, scoring nine times in seven games so far this season, bringing his total PSG record to 180 goals in just 224 appearances. 

During his time in Paris he's won four Ligue 1 titles and three Coupe de France trophies, as well as being crowned the UNFP Ligue 1 Player of the Year for the 2021/22 campaign. 

Discussions about Mbappe's future will only raise further questions surrounding PSG's ability to meet Financial Fair Play regulations, with the club facing significant criticism over their dealings in the transfer market in recent years. 

Following the Frenchman's decision to extend his spell in Paris this summer, La Liga wrote an extraordinary statement detailing their intentions to report PSG's actions to UEFA and the French authorities. 

The Spanish league claimed that they would file a complaint as they believed the terms of Mbappe's new contract at PSG 'threatens the economic sustainability of European football.' 

LaLiga president Javier Tebas has spoken out frequently against the spending of Man City and PSG and the Spanish league also announced in June that it was planning to take legal action against both clubs for 'continuously breaching the current regulations of Financial Fair Play'.

In September, PSG were also fined £56m by UEFA after breaking FFP rules. 

However, despite having an annual revenue of £480M last year according to the accountancy firm Deloitte, they only had to stump up £8.7m, with the remaining balance conditional, depending on compliance with targets set in their settlement agreement with UEFA. 

The current FFP regulations are due to be altered next year, with UEFA putting in place rules that will restrict clubs to spending a certain percentage of their revenue across 12 months on wages, transfers and agent fees. 

This limit will stand at 90 per cent in 2023, will drop to 80 per cent the following year, before decreasing even further to 70 per cent from 2025.
