Serena Williams has insisted that she can win all four Grand Slams in 2013 ahead of the Australian Open in January.
The American, who is a 15-time Grand Slam champion, held all four trophies in 2002-03 and enters the Australian Open having won 31 of her last 32 matches.
When questioned on whether she should claim all four majors next year, she told reporters: "Absolutely, Whoever wins the Australian Open will have that same thought.
"There is no way that Victoria (Azarenka) or Maria (Sharapova) or maybe some other players don't feel the same way. So I think I definitely feel that way."
Williams won 58 of her 62 matches in 2012, including titles at Wimbledon, the Olympics and the US Open.
