Tennis-Djokovic backs 'funny' Collins, says tennis could loosen up a bit
Novak Djokovic has backed Danielle Collins for her cheeky response to hostile fans at the Australian Open and said the sport could afford to take itself a little less seriously. Collins blew kisses at the booing crowd and thanked them for paying for her next five-star vacation after beating local Destanee Aiava in the second round on Thursday.
