Serbia's Novak Djokovic won a record seventh ATP Finals tennis title with a 6-3 6-3 victory over Jannik Sinner in Turin, Italy. Djokovic overtook Roger Federer's haul of six ATP Finals titles and becomes the first man or woman to spend 400 weeks as No.1.
This year he won three Grand Slam titles to draw level with Australian Margaret Court's all-time record of 24 and became the only man to win a career Grand Slam - all four major titles - three times.
