Novak Djokovic has set a new record with 378 weeks in total as the world No 1, eclipsing Steffi Graf’s record of 377. The 35-year-old marked the moment on court at the Dubai Tennis Championships by watching a video of himself as a seven-year-old talking about his dream to be world No 1. Djokovic said he was ‘thrilled to be among tennis’s greatest’ and acknowledged the support from his family and his team that helps him continue to perform at the top level of tennis.
