LONDON — Swiss maestro Roger Federer will have an early chance to disprove the notion that Novak Djokovic is untouchable when they meet in their second round-robin match at the ATP World Tour Finals on Tuesday.
Federer outclassed Tomas Berdych 6-4 6-2 to kickstart his 14th consecutive appearance at the season-ender on Sunday, a few hours after world number one Djokovic had demolished Japan's world number eight Kei Nishikori 6-1 6-1.
Both already look odds on to take the top two spots in Stan Smith Group but Tuesday's 43rd meeting between the pair (both have won 21) looks set to decide who will advance to the semi-finals as group winner.
