Medvedev is the defending champion, having won all five of his events last year. The event takes place between November 14-21.

Medvedev joy at 'one of the best victories of my career'

Match of the Day

Hubert Hurkacz has had a breakthrough season and he pulled off a big shock when he knocked Daniil Medvedev out of Wimbledon in the quarter-finals.
The Pole will be hoping to pull off a similar result on day one.
Matteo Berrettini has not had the best few months since his spell on grass, but he has home advantage - and that will put pressure on Alexander Zverev.
