Andy Murray will step into the unknown when he takes to the court at the Australian Open as a grand slam champion.

Murray ended his long wait for a maiden major at the US Open in September by beating Novak Djokovic in an epic five-setter.
The Scot has been candid about the fact the success has led to a more relaxed build-up to Melbourne but he admits to having no idea how it will affect him when he meets Dutchman Robin Haase in his opener.
"I have no idea how I'm going to play here," he said.
"I have no idea how I'm going to feel when I go on the court.
"I said I feel more relaxed but I don't know the day when I play my first match, I could be unbelievably nervous.
"I don't know what effect it will have on me until I'm put in that situation."
No player in the Open era has ever followed up his first grand slam title by winning the next one and Murray conceded it was a tough task to go back to back.
He added: "I know how hard these events are to win.
"If I don't win the Australian Open, I don't think it will be down to having won the US Open. It's down to the level of competition and how tough it is to win these events rather than what happened four or five months ago."
Murray could have hoped for an easier opening assignment.
Haase may be 53 in the world rankings but his big-hitting style makes him a tricky opponent.
Murray experienced that first hand at the 2011 US Open when he had to come from two sets down to win their second-round encounter.
"He's a very good player, very talented," said Murray. "I had a tough match with him at the US Open, he likes playing on big courts.
"He tends to come out firing and going for big shots, playing extremely aggressive. So I'll need to be prepared for that.
"When I played him in New York it was a very, very tough match and I expect the same thing here."
Murray won the warm-up event in Brisbane and appears primed to make another serious challenge in Melbourne after reaching the last four here 12 months ago and the final in both 2010 and 2011.
"I feel good just now," he said.
"I've been practising well, moving well in practice."
