Paris Saint-Germain have received a world record bid of 300-million-euro ($333 million) for Kylian Mbappe from Saudi club Al Hilal, a source close to the negotiations told AFP on Monday.
"The club has given permission to Al Hilal to speak with Mbappe," the PSG source said.
Mbappe, 24, has one year left on his contract with PSG, who want him to leave now rather than for nothing next summer.
The standoff between Mbappe and the French club reached a new peak at the weekend when they dropped him from their squad to tour Japan and South Korea.
There have been suggestions that Mbappe would not be selected for an entire year if he fails to find a solution with PSG.
Mbappe, the club's all-time top scorer with 212 goals in 260 appearances, remains the second most expensive player in history behind his PSG teammate Neymar.
"In the group so far that have expressed their interest there are Manchester United, Inter Milan, Barcelona, Tottenham and obviously the Saudi club and Real Madrid," the source said.
Riyadh-based Al Hilal are one of the clubs owned by Saudi Arabia's Public Investment Fund (PIF).
