Novak Djokovic and Stefanos Tsitsipas will clash on Saturday at the Dubai Duty Free Tennis Championships final.
The World No. 1 saved three match points before defeating Gael Monfils 2-6, 7-6 (10/8), 6-1.
"It was an amazing escape," said Djokovic. "Gael was playing as well as he ever has. It was difficult to go through him. I have good defence, but what he did today was unbelievable."
Meanwhile, Tsitsipas cruised past Britain’s Daniel Evans 6-2, 6-3.
