Andy Murray's mother Judy says her son can enjoy even more success in 2013, and has praised the impact that coach Ivan Lendl has had on his career.
Murray enjoyed his best year in tennis,
winning Olympic gold
his maiden Grand Slam title
at the US Open, and was
runner-up at Wimbledon.
"It's been a significant year for him," Judy Murray told the BBC.
"It's given him a lot of confidence. He's worked even harder than before to go after another Slam in Australia."
joined forces with eight-time major winner Lendl 12 months ago
and the partnership has been a huge success, as Murray threatens to reach the top of the world rankings.
Sharing the SW19 stage
"The speech he made at Wimbledon showed everyone at home who thought he was a hard, heartless competitor what it meant to him."

"He's been a crucial factor in Andy's improvement and success this year," said Judy.
"The wonderful thing about Ivan is that he's very similar in character to Andy, not least they have the same awful sense of humour! But seriously, he's very driven, very dedicated and he absolutely has his eyes on the prize.
"He knows what you have to go after and he knows that you have to be very single minded about going after it.
"He's got a real sense of direction, a real toughness and he's really helped Andy with the mental side of the game, about being able to reset if you suffer a disappointment, a bad call or a run of bad games. That's allowed him to play his best tennis for much longer periods of time."
Murray, from Dunblane, recently
finished third in the BBC's Sports Personality of the Year award
and has been in Miami for his annual pre-season training camp, but will take a short break before flying east.
"He's come home for Christmas for a couple of days for the first time in about four years. He leaves on Christmas night to go to Abu Dhabi to play in an exhibition event and then on to Brisbane for the warm-up tournament before the Australian Open," his mother explained.
And Judy, who
captains Great Britain's Fed Cup team,
feels there is a crop of young Scottish players ready to step onto the world stage.
Maia Lumsden, a 14-year-old from Glasgow, beat fellow Briton Gaby Taylor, from Hampshire, in the final of the Orange Bowl event, considered one of the most prestigious in the world junior game.
The Fed Cup skipper added: "Anna Brogan is the best girl in Britain in the 1997 age group. Maia is the best born in 1998. For 1999 there's Anastasia Mikheeva who's the number two in Britain. And born in 2000, there's Ali Collins from Dunblane who's the British number one under 12.
"There's a bright future ahead for British girls' tennis if we can get the next stage of the players' development right."
