British No.1 Jack Draper was left hailing an “unbelievable” practice session after spending time on court with Novak Djokovic. Just four days out from the start of the Australian Open, Draper joined forces with the 24-time Grand Slam champion, who is currently being coached by Andy Murray.

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.

Jack Draper has lined-up an intriguing practice session at Melbourne Park on Wednesday as he ramps up his preparations for the Australian Open. Draper, 23, is yet to go past the second round down under, a record he'll be expected to change this month having risen to No.15 in the world.

Novak Djokovic's former rival-turned-coach Andy Murray does not want the Serbian to suppress his emotions on court and is even willing to be the target of any angry outbursts as long as the 24-times major winner gives his all at the Australian Open.

Andy Murray jokes he's 'here to sabotage' Novak Djokovic after the Serbian star was 'single-handedly responsible' for him never claiming an Australian Open title
