Tennis icon and world number one, Novak Djokovic beat Alexander Zverev 6-3 7-6(4) on Friday to seal a last-four spot in the London ATP finals.
The 33-year-old Serb will face U.S. Open champion Dominic Thiem in Saturday’s semi-final while Rafael Nadal plays Daniil Medvedev as tennis fans brace for an expected mouth watering clash between Nadal and Djokovic in the finals.
Djokovic was defeated by Russian Daniil Medvedev in his group on Wednesday so  he needed to beat Germany’s Zverev to avoid a group stage exit, which he did comfortably.
Sunday’s final will end the tournament’s memorable 12-year stay in London before it re-locates to Turin.

“In contrast to the match against Daniil I found the right shots at the right time,” he said. “I have tremendous respect for Sascha, a great player and not easy to return 140mph first serves. It was anybody’s game for most of the match.”
Djokovic wants to equal Roger Federer’s record of six ATP Finals titles, while Nadal seeks a first ATP finals title in his career.
