In Tennis, Alexander Zverev upset world number one Novak Djokovic in straight sets to claim the season-ending ATP Finals and earn the biggest victory of his career. Djokovic was the heavy favourite but outclassed 6-4, 6-3 by the German last night in London.

The 21-year-old Zverev became the youngest champion of the season-ending event since Djokovic claimed the first of his five titles a decade ago and the first from Germany since 1995.

Djokovic was attempting to tie Roger Federer’s record of six titles but followed the same path as the Swiss great, who lost to Zverev in the semi-finals at the O2 Arena.

Zverev also became the first player to beat both Djokovic and Federer in the same ATP Finals.
