Federer perfect in Perth but fears Djokovic domination Down Under

PERTH, Australia - Roger Federer kept up his impressive early-season form after another flawless week of singles performances at the Hopman Cup in Perth - and then declared Novak Djokovic the man to beat at the Australian Open.

Federer will be aiming for a third successive Australian Open title and looked in good shape as he and Belinda Bencic retained the Hopman Cup for Switzerland with victory over Germany's Alexander Zverev and Angelique Kerber in the final. Federer won all four of his singles matches in the mixed-team competition.

The 37-year-old used the Hopman Cup as his launching pad for his last two Grand Slam successes in Melbourne.
