Paris: Kristina Mladenovic called for a football-style VAR system to be introduced in tennis after her opponent profited from a double bounce to help knock the Frenchwoman out of her home Grand Slam.

Mladenovic was 5-1 up and with a set point against Laura Siegemund when the German scooped a winner despite the ball appearing to bounce twice. 

The incident was missed by chair umpire Eva Asderaki.

World number 44 Mladenovic pleaded in vain before Siegemund took full advantage, racing into the next round with a 7-5, 6-3 win.
