Novak Djokovic is often portrayed as the bad boy of tennis, but stars at Wimbledon have shared a different view on the 20-time Grand Slam champion's on-court behaviour

Novak Djokovic has been a professional tennis star for over 20 years, and is revered as an icon of the game - but his behaviour isn't always as professional.

Novak Djokovic expressed pride in his performance Thursday, telling the crowd he "executed perfectly" in a 107-minute sweep of Daniel Evans, which helped him advance to Wimbledon's third round a record 19th time.
