Roger Federer, Rafael Nadal and Novak Djokovic will face the challenge of the fast-rising gen-next of tennis players at the ATP Finals.
The "Big Three" remain the men to beat at the season-ending tournament in London -- as they were when they first all played together at the event in 2007.
But the eight-man field at the O2 Arena contains a crop of exciting young players who have their eye on smashing the dominance of the old guard.
Germany's Alexander Zverev, who triumphed last year, is joined by Russia's Daniil Medvedev, Stefanos Tsitsipas of Greece and Italy's Matteo Berrettini.
Dominic Thiem of Austria, at 26 slightly older than his young rivals, completes the field at the tournament featuring the year's best players, which starts on Sunday.
