Djokovic leads the duel 25:11, but Murray took memorable victories over him and won the duel US Open in 2012 And Wimbledon a year later.
However, he lost to Djokovic at the Melbourne shows in 2011, 2013, 2015 and 2016 and also lost the French Open final in 2016.
Murray replaced Djokovic as world number one at the end of the 2016 season and finished the year on a 24-match winning streak, but a hip injury a year later would ultimately derail his career.
Murray announced in the summer that the Paris Olympics would be his final tournament, and he made it to the men's doubles quarterfinals alongside Dan Evans before being eliminated.
“I will be joining Novak’s team in the off-season and helping him prepare for the Australian Open,” Murray said.
“I’m really excited and looking forward to spending time on the same side of the net as Novak for a change and helping him achieve his goals.”
Djokovic made changes to his team this year and, among other things, parted ways with long-time coach Goran Ivanisevic.
The Olympic medal was the only title he won in 2024, and he ended his season early after suffering an unspecified injury.
It is the first season since 2005 in which he has not won an ATP event and only the fourth since 2008 in which he has not won any of the four Grand Slam titles.
“I am looking forward to starting the season with Andy and having him by my side in Melbourne, where we have shared many extraordinary moments throughout our careers,” Djokovic added.
