Federer seeking revenge over Djokovic at ATP World Tour Finals

Swiss tennis ace Roger Federer will start his bid for a seventh title at the season-ending ATP World Tour Finals in London with a match against Novak Djokovic, where he would be seeking revenge for the recent Paris loss.

According to Sport24, after one of the worst campaigns of his illustrious career, Federer arrives for the prestigious event at London's O2 Arena looking to finish the year on a high note and he has an opportunity to make an immediate impact when he faces world number two Djokovic on Tuesday.

Federer has tumbled to sixth in the world rankings this year and just barely qualified for the ATP's eight-man showpiece tournament, the report said.

Federer would dearly love to prove he can still shine against the sport's big guns by beating Djokovic in his opening match before further Group B clashes against Juan Martin del Potro and Richard Gasquet, the report added.

The Swiss master said that it was unusual to go back-to-back matches against Djokovic, but he was always excited about the challenge, adding that he has had a good couple of weeks now, and most important now is to recover as much as he can.
