Novak Djokovic said beating Alexander Zverev on Wednesday was a "testament" to his ability to compete at the highest level as the 38-year-old reached the semi-finals at Roland Garros to inch closer to a record 25th Grand Slam title.

Novak Djokovic continues his quest for a standalone record 25th Grand Slam title by swatting aside Alexander Zverev in the French Open quarter-finals and setting up a semi-final with Jannik Sinner.

Novak Djokovic is through to the French Open semifinals after outclassing Alexander Zverev in a 4-6, 6-3, 6-2, 6-4 win Wednesday night. Djokovic, 38, is a decade older than Zverev, but he made his opponent look like he was stuck in the past with a performance full of variety and inventive angles that contrasted sharply with the German’s one-dimensional baseline play.
