Novak Djokovic had his mistakes cheered by disrespectful fans during his defeat to Roger Federer on the ATP Finals on Thursday. The Serbian was beaten 6-4, 6-3 by a flawless Federer at the O2 Arena in London, subsequently bringing to an end his hopes of winning the tournament for a record-equaling sixth time. A portion of the crowd, which was awash with red flags in support of Federer, was heard cheering Djokovic s errors throughout the match, and clapping loudly after each of his three double faults. Former England number one, Greg Rusedski, slammed the behavior, calling it too much. I think it s disrespectful when you re clapping double faults. That s too much, Rusedski said during the live broadcast on Amazon Prime. I don t mind fans supporting one guy over the other — that s your choice — but there s a certain etiquette you have to have out there. Annabel Croft, a former British number one, echoed Rusedski s comments, saying: I felt sad for Novak tonight. What does he have to do to get a crowd on his side? He was playing some beautiful tennis and it was just met by polite applause. Some of his double faults were being clapped and cheered. I did feel a tinge of sadness for him because he looked a little lost out here and it can t be easy when you re taking on 20,000 people.
