All eyes will be on Andy Murray and Novak Djokovic over the next fortnight at the Australian Open as the Scot sets his former rival a new challenge, having crowned him tennis' 'GOAT'

If Novak Djokovic can win a 25th major title in the coming days, he will bolster his claim to be considered the greatest athlete in history, according to his new coach Andy Murray.

John McEnroe believes Andy Murray could come out of retirement once he's done working with Novak Djokovic at the Australian Open. The tennis legend hung up his racket back in the summer after playing doubles with Dan Evans at the Paris Olympics.
