Daniil Medvedev’s dramatic comeback win over Alexander Zverev in the pair’s Australian Open semi-final clash is just another epic chapter in one of sport’s most bitter rivalries.

With Medvedev ranked third in the world and Zverev seventh, the pair often cross paths both on and off the court, but have made no secret of the bad blood that exists between them.

Last season Zverev angrily branded Medvedev ‘one of the most unfair players in the world’, while his counterpart firmly shut down claims that they were once close friends.

The rivals met six times last year, including an explosive showdown in Monte Carlo. The verbal sparing that followed sparked the most pointed and public spat to date, with every moment laid bare in the behind-the-scenes Netflix documentary Break Point.
