Novak Djokovic began his attempt to equal Roger Federer’s record number of ATP Finals triumphs with a straight-sets 7-6 (7/4), 6-2 win over Casper Ruud on Monday. 

World No. 1 Djokovic is looking to complete a remarkable year with a sixth Finals title after only just missing out on claiming all four Grand Slams in a single season, and got off to a strong start against eighth seed Ruud, winning in around 90 minutes.
