Former world number one Novak Djokovic is through to the last four at the Fever-Tree Championship at Queens after he defeated Adrian Mannarino of France in straight sets to record his 800th career win.

The Serbian world number 22 defeated his French opponent 7-5 6-1 in their last eight clash on Friday evening.

He will now face another Frenchman Jeremy Chardy for a place in the final on Saturday after he defeated American Frances Tiafoe 6-4 6-4.

Top seed Marin Cilic of Croatia and Nick Kyrgios of Australia will meet in the other semi-final.

On his 800th win, the 12-time Grand Slam champion said: “It’s a milestone, and of course it’s a great achievement.”

“Every achievement is a great achievement. I should be happy for it and proud of it.

“When you work all your life for something and then you get rewards for it, of course it’s obviously very positive and I’m thrilled.

“I’m grateful, as well, as I’m able to play so many matches and to win so many matches in my career.

“It’s still the sport that I love with all my heart. I put in that heart every single day, and I’m very glad to be able to play semi-finals here after Rome and Roland Garros tournaments that went pretty well for me.” He concluded.

Novak Djokovic has struggled for form since returning from an elbow injury which kept him out for the better part of the last one year but recent displays suggest that he’s gradually regaining the form that made him the best player in men’s tennis.
