MELBOURNE, Australia — Novak Djokovic and Andy Murray have known each other for a quarter of a century. They played from the age of 12, meeting 36 times as professionals, including 10 Grand Slam matches. Yet they've never been able to talk shop and freely trade all sorts of thoughts — about tennis and otherwise — until now.

Andy Murray insists that he will be only too happy to face the wrath of Novak Djokovic, should he find himself on the receiving end of a few mouthy outbursts at next week’s Australian Open.

Nick Kyrgios says he is good for tennis and the sport will get a boost from his return to Grand Slam action at the Australian Open.
