Switzerland's Roger Federer answers questions during a press conference at the Australian Open tennis championship in Melbourne, Australia, Saturday, Jan. 14, 2012.

MELBOURNE, Australia — After taking three of the four majors and gaining the No. 1 ranking last season, Novak Djokovic is going for prizes beyond Grand Slams in 2012.

An Olympic gold medal, he thinks, would go nicely in his collection.

Djokovic told a news conference Saturday, only days before he starts the defense of his Australian Open title, that the Olympics are "one of the biggest priorities this year."

The Serbian star won the Olympic bronze medal in 2008 at Beijing, when then No. 1-ranked Rafael Nadal took the gold.

Roger Federer also has an Olympic gold medal from Beijing, although his is in doubles.
