Nick Kyrgios let rip at "selfish" fellow tennis star Alexander Zverev on Monday after the German was seen partying despite promising to self-isolate following Novak Djokovic's Coronavirus-hit Adria Tour.

Djokovic, Grigor Dimitrov, Borna Coric and Viktor Troicki all subsequently tested positive for COVID-19. While Zverev tested negative, he released a statement afterwards vowing to self-isolate, only to be spotted at a busy bar, apparently over the weekend, in footage that went viral.
