The Frenchman has been involved in a standoff with PSG after refusing to sign an extension to his contract, which expires next summer.
PSG believe that Mbappe has already agreed to sign for Real Madrid at the end of next season, and they want to sell him this summer rather than allow him to walk away for nothing in June 2024.
They gave Mbappe permission to speak with Saudi Arabian club Al-Hilal after accepting a world-record bid of £259m last month.
However, the forward had no interest in completing a move to the Saudi Pro League, and subsequently refused to meet with Al-Hilal delegates.
The stalemate between player and club resulted in Mbappe being left out of PSG’s squad for the pre-season to Japan and South Korea.
Luis Enrique’s side are set to return to their training base on Monday, but according to BBC Sport, the 24-year-old has been barred from working with the main first-team squad.
The report claims that the France international will train with the ‘loft’ group rather than the ‘A’ training group, as they finalise their preparation for the new season.
There are no signs that a resolution is close to being reached after Mbappe supposedly turned down PSG’s latest offer, which included a sale clause in his contract for the end of the season.
The Parisians have considered sending Mbappe out on loan for the season, an idea that has seemingly caught the attention of two Premier League clubs.
Chelsea are believed to be interested in a loan move, while a recent report claimed that Mbappe would consider joining Liverpool on a temporary basis.
With Mbappe’s future shrouded in uncertainty, PSG are reportedly set to strengthen their forward line with the addition of Goncalo Ramos from Benfica.
The reigning French champions will begin the defence of their title on Saturday when they welcome Lorient to the Parc des Princes.
