Andy Murray failed in his bid to make it a hat-trick of titles at the Shanghai Masters after losing a three-set thriller to Novak Djokovic.
In their first meeting since Murray's win in the US Open final, Djokovic triumphed 5-7 7-6 (13-11) 6-3.
Murray edged the first set, which had seven breaks of serve, with Djokovic reacting angrily by smashing a racket.
Djokovic saved five match points in the second set before taking the tie-break and breaking Murray twice in the third.
