Kylian Mbappe is left out of PSG's pre-season tour of Japan

Kylian Mbappe has been left out of PSG's pre-season squad to tour Japan, according to a report.

Mbappe has caused controversy over the last few years with the French side, regularly expressing his frustrations with the club about various topics.

His latest complaint came when he said he would be leaving the club when his contract expires next year if he is not sold in this transfer window.

PSG have since pleaded with him for a decision that suits both parties to be reached, but little progress has been made on a call that is important to both club and player.

According to L'Equipe, the French champions believe Mbappe has an agreement in place to join Real Madrid.

Mbappe has been long linked with Madrid, opting to sign a new contract with PSG rather than join the Spanish side last summer.

But things have been negative since, with the Frenchman regularly speaking out against the hierarchy and threatening to walk away for free when his contract expires.

PSG president Nasser Al-Khelaifi asked Mbappe to sign a new deal or leave this summer, with the thought that he has agreed to move to Spain next year for nothing.

The 24-year-old came off the bench to score in PSG's friendly win over La Havre on Friday, but was later left out of the travelling squad.

Thanks to the eye-watering extension he signed to stay with PSG, Mbappe is set to pocket a mammoth loyalty bonus, believed to be in the region of £68m according to El Pais, if he stays with the club for another year.

All signs point to that happening with a potential move to Madrid on the cards next summer, but PSG will do all they can to fight it this transfer window.

The French side will take on Cristiano Ronaldo's Al-Nassr in their next pre-season friendly in Japan on Tuesday before games against Cerezo Oasaka, Inter Milan and Jeonbuk Hyundai Motors.
