The draw for the Nitto ATP Finals has been set with world number one Novak Djokovic and US Open champion Daniil Medvedev leading the field.

Djokovic, who has displayed his dominance at the big events, will be joined by Stefanos Tsitsipas who reached his first grand slam final losing in five sets to Djokovic in Paris.
Completing the Green group will be Andrey Rublev, who reached the Cincinnati final and showed another consistent season, and Casper Ruud who won five titles this season as well as showing his versatility on non-clay courts.
Headlining the Red Group is US Open champion Daniil Medvedev who won his first grand slam in New York beating Djokovic in a dominant final from the Russian.
Medvedev will be happy with his group with former ATP Finals champion Alexander Zverev joining him in the Red Group.
