It's Tsonga vs Fed Defending champion Roger Federer will take on France's Jo-Wilfried Tsonga in the singles final, looking to win the title for a record sixth time.
The showpiece, season-ending match at London's O2 Arena will be Federer's 100th final. Tsonga booked his place by downing Tomas Berdych of the Czech Republic 6-3, 7-5 to set up a rematch against Federer, who beat the Frenchman 6-2, 2-6, 6-4 last Sunday in the opening round-robin match of the event.
