Murray handed tough draw for ATP Finals

Andy Murray has been drawn in the same group as world number one Roger Federer for the Barclays ATP World Tour Finals.

Murray and Federer are joined by US Open champion Juan Martin del Potro and Spain's Fernando Verdasco in Group A at the 02 Arena in London.

Group B features Rafael Nadal, Novak Djokovic, Nikolay Davydenko and Robin Soderling.

Soderling initially failed to qualify for the prestigious eight-man event but was handed a place when Wimbledon finalist Andy Roddick was forced to pull out through injury.

The round robin group format will decide the four players who advance to the semi-finals, with the group winners kept apart in the last four.

All singles matches will be the best of three tie-break sets and get under way on Sunday.

The final is scheduled for November 29 with a first prize of $770,000, although that rises to more than $1.6 million if the champion remains undefeated throughout.
