Roger Federer hopes being in the unusual position of underdog will help him add to his record tally of 17 tennis grand slam titles at the Australian Open.
The Swiss great has been overshadowed by Rafael Nadal and Novak Djokovic in recent years, with the 2012 Wimbledon crown his only grand slam title since his 2010 victory at Melbourne Park.
Federer's dropped to sixth in the world rankings, but the 32-year-old says he can now fly below the radar, and he's beginning to get used to being in the shadows of Nadal and Djokovic, who won three of the four grand slams in 2013.
