World number one Roger Federer has played down suggestions he could complete a clean sweep of Grand Slams in 2010.
Rod Laver is the only other tennis player to have achieved that feat back in 1969 but 16-time major winner Federer says he is relaxed about the possibility of a medals haul.
Tennis experts have argued it could be the Swiss superstar's last chance to make such a landmark because Rafael Nadal - his French Open nemesis - continues to be dogged by injury.
Federer, 28, said: "I won't put the entire calendar just around trying to win the calendar Grand Slam.
"It's something if it happens, it's great, but it's not something that's my number one goal. Whatever happens, happens."
