Roger Federer and Novak Djokovic in same group for ATP Finals in London

Fitness concern: Rafael Nadal PICTURE: GETTY

NOVAK DJOKOVIC and Roger Federer have been drawn in the same group for the ATP Finals in London.

The pair will do battle in the Bjorn Borg group at the O2 Arena and are joined by Dominic Thiem and Italian debutant Matteo Berrettini.

Top seed Rafael Nadal avoided Federer and instead finds himself in a quartet with US Open runner-up Daniil Medvedev, Australian Open semi-finalist Stefanos Tsitsipas and defending champion Alexander Zverev at the year-ending tournament, which begins on Sunday.

Doubts remain about Nadal’s fitness but he is hopeful of being able to compete.

The Spaniard, who suffered an abdominal injury at the Paris Masters last week, tweeted: ‘Despite having a small strain, I will travel to London. Thursday or Friday I will start serving. The idea is to be able to play in London.’

Nadal, 33, has overtaken Djokovic at the top of the world rankings but would need to reach the final and win all three of his group matches to guarantee staying at No.1.
