Here's a short story:

(CNN) -- Novak Djokovic is on course for a "fab four" of Australian Open titles when the tournament begins in Melbourne next week -- and the defending champion says all he needs is love. 

The Serbian second seed could become the first man to win four straight titles at the opening grand slam of the season and he says he has been in unstoppable form since popping the question to his girlfriend Jelena Risti. 

"I got engaged in September," Djokovic told the media assembled under Melbourne's sunny skies Friday. "But since we got engaged I haven't lost a match so I guess the wedding should come very soon!" 

The 26-year-old says the couple have yet to set a date for the big day so for now he is able to focus on beginning his on-court campaign in Australia. 

Djokovic may be engaged but he is also exploring an on-court relationship with new coach Boris Becker, himself a two-time Australian Open champion. 

"It's great to see Boris as elegant as ever he's a legend of our sport," said Djokovic, nodding to Becker, who was watching in the crowd wearing a smart beige blazer. 

"He's not been in Australia for 15 years so he's surprised to see how much has been done since then and for me it's an honor to have him alongside other team members. 

"We're going to try and make a success of our partnership, it's just the beginning." 

Djokovic, who won his first grand slam in Australia in 2008, faces Slovakia's World No.90 Lukas Lacko in the first round.  (End of story)
