Also watch a spectacular tennis tournament with world top players LIVE on this site on Sunday

No warm-up, no second serve, no let, coaches with a microphone, interviews during the game and throwing your racket is allowed. That is the Ultimate Tennis Showdown, a fast and spectacular variant of traditional tennis. The three-day event in London, including Holger Rune, Gaël Monfils, Andrej Roeblev and Alex de Minaur, can be seen live on this site from Friday evening. Exclusively for subscribers.
