A group of Monaco supporters has criticised Kylian Mbappé and his entourage for their conduct during the summer transfer window as the teenage France forward edges close to joining Paris Saint-Germain.

Reports in France have suggested PSG are in talks over a €140m (£128m) move that would see the 18-year-old join initially on loan in a bid to avoid financial fair play sanctions from Uefa after the £198m transfer of Neymar. The Brazil forward Lucas Moura would also move to Monaco as part of the deal.

Mbappé was dropped for the win over Metz on Friday following a training ground argument with his team-mate Andrea Raggi and has not been able to agree terms on a new contract worth a reported £130,000 a week.

That led Ultras Monaco 1994 to issue a statement on Monday that condemned his behaviour and warned the player who scored 26 goals in 44 matches during his first full season as a professional.

“In recent times we have witnessed with astonishment and indignation the figures quoted by the media about the transfer of Mbappé but also about the salary to renew his contract with our club,” read the statement.

“We think that no player is worth so many millions of euros. We believe football is for everyone and values such as the love of the shirt and respect for the club where you been your career. We cannot accept that one of our players has acted in that way and demand such figures, without having disputed more than a few dozen matches at professional level.

“We would like to remind Kylian Mbappé and his clan that nothing and nobody is above the institution of AS Monaco FC. We therefore strongly hope our representatives will take the necessary decision to close this case if these requirements are confirmed while taking into consideration that it is essential not to strengthen the competition for the title.

“Since their arrival, they have shown us their ability and we fully believe in them to build a team capable of defending the title, with or without Mbappé.”

Mbappé has attracted the attention of most of Europe’s biggest clubs, with Real Madrid confident they had secured a deal to sign him last month. It is understood the player and his father have made it clear PSG is their preferred destination given concerns over how often he would play at the Santiago Bernabéu with Cristiano Ronaldo, Gareth Bale and Karim Benzema all vying for starting spots.

With PSG under pressure to balance the books after the world-record purchase of Neymar, they are believed to have requested a deal for Mbappé that would see them pay a small percentage of the transfer fee this year, with the balance due next summer.

The Brazil midfielder Fabinho is also understood to have told Monaco he wants to move to Paris, with a deal worth an additional £40m being discussed.

The Lyon president, Jean-Michel Aulas said this week: “I’m afraid that we get into a bicep surge, which is not useful. Will it improve the performance of PSG if Mbappe arrives? If you stack, with supernatural money, the best players in a team, you do not have any more competition.”
