Serbia’s Novak Djokovic has beaten Andy Murray to the International Tennis Federation’s (ITF) annual men’s World Champion award, with American Serena Williams taking the women’s prize for a third time.

Djokovic, who ended a second successive year on top of the ATP rankings, successfully defended his Australian Open title, reached the final at the French Open and US Open and claimed five other titles including the season-ending Tour Finals.

Britain’s Murray was a strong contender for the honour after beating Djokovic at the US Open to win his first major title.
