(CNN) -- Before the world's top tennis players enjoy a much-deserved break there is one last men's title to be decided in 2010: the ATP World Tour champion will be crowned at London's O2 Arena.
The season-ending championship takes place from 21-28 November and will see the eight highest-ranked singles players in the world clashing in the British capital for the second year in a row.
The prestigious tournament has existed in some form since 1969 and has been held at locations across the world including a 13-year stint at Madison Square Gardens in New York and most recently in Shanghai, China.
Each player contests a minimum of three matches in a round-robin style competition before the top two from each group progress to the semifinals and final, for the chance to compete for the $5 million prize.
In the 2010 line-up world number one Rafael Nadal is joined in group A by Serbia's Novak Djokovic, tournament debutante Tomas Berdych of the Czech Republic and eight-time finalist Andy Roddick.
While in group B home favorite Andy Murray has been matched with Spain's David Ferrer, Sweden's Robin Soderling and four-time tournament winner Roger Federer.
The top eight doubles pairings in the world will also battle it out at the World Tour Finals, with the reigning champions and nine-time grand slam men's doubles champions the Bryan brothers, the pair to beat.
In 2009 the then world number six Nikolay Davydenko of Russia took the much coveted singles title, beating fifth-ranked Juan Martin Del Potro of Argentina in the final.
But who will become the year-end champion in 2010?
