Kylian Mbappe 'to quit if Paris Saint-Germain don't win Champions League'

Kylian Mbappe will allegedly request to leave Paris Saint-Germain next summer if they do not win this season's Champions League.

While Mbappe has a contract until the end of the 2021-22 campaign, speculation has persisted regarding a future transfer to Real Madrid.

According to reports in Spain, the World Cup winner is ready to express a desire to take on a new challenge elsewhere if PSG do not end their wait for the Champions League.

Despite the money spent by the club's owners, PSG have not progressed past the quarter-final stage in recent years, which has allegedly left one of their star men frustrated.

The French champions are currently on course to reach the knockout stages as group winners, with a five-point advantage being held over Real after two games.

Mbappe missed out on PSG's 3-0 victory over Los Blancos last month due to injury.
