Clearly during the summer/fall, Djokovic really struggled, but everyone has at one time or another. However the Serb just knocked out No. 1 Andy Murray in Doha. Novak has been phenomenal at the AO, winning 2016, 2015, 2013, 2012, 2011 & 2008. Will the No. 2 be the favorite next week at the Aussie? Sure he will, but Murray is extremely confident, having shocked Djokovic in the ATP Final. At the 2017 AO, if they reach the final again, who ever wins, it should go for hours. Delicious.
