World No.1 Rafael Nadal's coach and uncle Toni Nadal has said that winning the Australian Open would be the biggest challenge for the player in 2014.
According to TennisWorldUSA.org, Toni Nadal said that it would achieve something that only Rod Laver did, which is twice winning the four Grand Slams.
He added that he does not put Nadal on a pedestal because he was part of his family, but because he knows that the World No.1 is one of the best ever.
Nadal had won this prestigious event in Melbourne four years back in 2009, after defeating Swiss ace Roger Federer in the title clash, the report said.
