Sly cannabis smoker puts off Novak Djokovic day before he crashes to Andy Murray final defeat (Video)

We have found Novak Djokovic's weakness. Cannabis.

The imperious tennis star isn't a fan of people smoking weed while he's playing tennis. The world No.1 complained vehemently that someone was toking a joint during his Rogers Cup semi final match with Jeremy Chardy on Saturday. "Someone is getting high, I can smell it. I am getting dizzy," Djokovic told the umpire in his semi-final match against Jeremy Chardy (which he won), according to the Telegraph. https://youtu.be/ZAmfrQy2saI Afterwards he told reporters: "You can't believe how bad it was. Whoever it is, I hope he doesn't come back tomorrow. He's probably on the seventh sky somewhere." It's was the second time that Djokovic complained a spectator was enjoying a sly reefer on court, after sniffing it out during his and Janko Tipsarevic's doubles loss to Edouard Roger-Vasselin. We don't know if the mystery marijuana fan was back at Sunday's final, but the Serb ended up losing to Andy Murray 6-4, 4-6, 6-3, with the Brit ending an eight-game hoodoo in the process. Everyone knows what to do at Wimbledon next year then...
