Novak Djokovic targets grand slams after 2012 heartbreaker
World No 1 aims to claim all four majors in 2013 after just missing target this year

Novak Djokovic believes he can become only the third man in history to hold all four majors at the same time in 2013 having come so agonisingly close last season.
The world No 1 missed out on joining Don Budge (1938) and Rod Laver (1962 and 1969) as just the third man to simultaneously possess the Australian Open, French Open, Wimbledon and US Open titles when he was beaten by Rafael Nadal at Roland Garros.
Having finished No 1 in the world for the second successive season, the 26-year-old Serb goes into the new campaign, which gets under way officially next week, with his confidence high.
"I won the last big tournament of the year in London [the ATP World Tour Finals] and I am hoping that I can continue playing well," said Djokovic.
"So, my ambitions are always high. I want to win every grand slam that I play."
The five-time major singles winner added: "Roland Garros is always at the top of my priority list and ambitions. It's the only slam I haven't won. I played in the final, which is a step further than ever before."
