10-time champion Novak Djokovic has broken his silence after refusing to give customary on-court interview after his Round of 16 win on Sunday. Djokovic crushed Czech Republic's Jiri Lehecka in straight sets (6-3, 6-4, 7-6)to set up a blockbuster quarterfinal tie with third seed Carlos Alcaraz. Taking to social media, Djokovic cleared the air on his refusal to give a post-match interview, accusing a 'famous sports journalist' of insulting him and Serbian fans during a live broadcast on Channel 9, the official broadcaster's of the Australian Open.
