Djokovic still the biggest rival, says Murray

World number one Andy Murray insisted Sunday that Novak Djokovic will remain his biggest threat in 2017, as the pair prepare for a potential first clash of the season in Doha this week. Newly-knighted Murray, speaking ahead of the first round of the Qatar Open which begins on Monday, said the Serb would continue to make life tough for him on court this year. "In terms of the number one ranking, Novak would be (the biggest threat)," Murray told reporters.
