Novak Djokovic on Eurosport: "Definitely one of the best ways to start a year. When he turned it around, wow, I thought I hope this is not payback time for yesterday.
"All the way, to the last shot, you never know with Andy. It's no strange occurrence for both of us to play three sets for three hours. It's a very physical battle. We're both going to need a little time to recover.
"To win here, against the biggest rival, is a dream start."
Well. That was fun. A thoroughly absorbing match that could have gone either way. Murray battled his way back into it in the second set but a few errors cost him. Djokovic will retain his title. We're nicely set for the Australian Open.
