Novak Djokovic has backed Danielle Collins for her cheeky response to hostile fans at the Australian Open and says the sport could afford to take itself a little less seriously.
Collins blew kisses at the booing crowd and thanked it for paying for her next five-star vacation after beating local Destanee Aiava in the second round on Thursday. Djokovic, who endured constant heckling from one fan throughout his third-round victory on Friday, said he had every sympathy for Collins and thought she had handled the situation well.
