Rafael Nadal will play Novak Djokovic as Spain take on Serbia in the inaugural ATP Cup final in Sydney.
Top-ranked Nadal came from a set down to beat Australia’s Alex de Minaur 4-6 7-5 6-1 and give Spain an unassailable 2-0 lead over the hosts.
World number two, Djokovic, had earlier beaten US Open finalist, Daniil Medvedev, 6-1 5-7 6-4 as Serbia beat Russia 3-0.
Djokovic beat Nadal in straight sets in last year’s Australian Open final and leads their head-to-head 28-26.
He has also not lost to Nadal on a hard court since the 2013 US Open final.
The Australian Open, the first Grand Slam of the year begins on 20 January, eight days after the ATP Cup finishes.
