Djokovic has won the most men’s grand slam titles of any player with 24 and will be hoping that Murray can help him reach a record-extending 25th title at the Australian Open in January.

“I am excited to have one of my greatest rivals on the same side of the net, as my coach,” said Djokovic in a statement, per the Associated Press.

“Looking forward to start of the season and competing in Australia alongside Andy, with whom I have shared many exceptional moments on the Australian soil.”

Murray shared Djokovic’s excitement around the new role.

“I’m going to be joining Novak’s team in the offseason, helping him to prepare for the Australian Open,” Murray said, per AP.

“I’m really excited for it and looking forward to spending time on the same side of the net as Novak for a change, helping him to achieve his goals.”

Murray enjoyed a successful playing career, winning three grand slam titles and two Olympic gold medals.
