Federer set for Djokovic O2 showdown

Six-time record champion Roger Federer has been drawn in the same round-robin group for the ATP World Tour Finals as defending champion Novak Djokovic.
Djokovic defeated Federer to win the season-ending event for the second time in his career. The pair are in Group B alongside Basel champion Juan Martin del Potro and Richard Gasquet - who is playing at the tournament for the first time.
In Group A, world No. 1 Rafael Nadal returns to London's O2 Arena for the first time since 2011 and is seeking a maiden triumph. The reigning French and US Open champion is set to face David Ferrer, Tomas Berdych and debutant Stanislas Wawrinka in his opening three matches.
