Paris Saint-Germain has left Kylian Mbappe out of its squad for a preseason tour of Japan and South Korea, casting further doubt on the forward's future at the French champion.

PSG gave no reason for the omission of France's captain but 24-year-old Mbappe has said for weeks that he is refusing to sign a new contract.

His omission from the tour will fuel fresh speculation that he could leave to join Real Madrid before next season.
