"Having spent some time with Andy Murray in the locker room earlier today, he is very relaxed and will now just spend some time on his own to get his thoughts together. In the practice session he was hitting the ball great.

"His level has remained high and consistent so he is feeling good going into this. He's in a really good frame of mind and he knows he is playing well."

And to continue the theme of social interaction, now is an opportune time to inform you that our BBC Sport vote is up and running.

We've gone with the obvious question - who is going to win? Andy Murray? Or Novak Djokovic?

In a week where plenty of focus has centred around Winton Churchill - considered by many to be the greatest Briton, Andy Murray was asked to name his greatest sporting Briton yesterday.

The Scot initially blurted out the names of golfer Rory McIlroy and boxer Joe Calzaghe, before sticking cyclist - and fellow Scot - Chris Hoy into the mix.

So that has got us thinking. If Murray wins his third Slam today, leaving him just a French Open victory away from a career sweep of the major tournaments, would that leave him as one of Britain's all-time sporting greats?

Yes? No? If not, who else should be in the top three and why? We want to know. So cram your thoughts into 140 characters on Twitter using #bbctennis, or text 81111 if you need more space. You can also tell us on the BBC Sport Facebook page., external Go, go, go!

Twelve months after that emotional defeat by Roger Federer (see 07:44), Murray was back in the final on Rod Laver Arena. And he may have been pleased not to see previous nemesis Federer facing him.

However, he was facing Novak Djokovic. The Serb was at the start of a season in which he would win three Slams and establish himself - at Federer's expense - as the world's best player.

Djokovic was far too strong with his power and movement, although Murray did not help himself in a nervous display.

Whether you're still lazing around in your comfy bed, out walking the dog in the freezing cold, or sat at the Rod Laver Arena wearing colourful facepaint, this is your 30-minute warning.

The stadium is filling up nicely, a whiff of excitement filling the Melbourne air. Andy Murray and Novak Djokovic are due to stroll out on court in about half an hour.

The boss is hovering around our desk, demanding to know why we haven't yet told you about the many ways which you can follow this humdinger across BBC Sport. So here is the lowdown.

Television coverage begins on 08:15 GMT on BBC One, while our colleagues at BBC Radio 5 live start slightly earlier at 08:00 GMT. That's in six minutes.

And of course, don't forget you can read about every serve, volley and mop of the brow right here. Never forget that.

If statistics make you all excitable and giddy, then you are going to be shaking uncontrollably with fact-based hysteria today. We have Djokovic/Murray-related numbers coming out of our ears. Here are a few to whet your appetite...

• Four-time champion Djokovic is aiming to become the second man to win five or more Australian Open titles (Roy Emerson is the other)

"Bright lights on a gloomy day. But roof expected to be open (to let the wind in) for Murray v Djokovic.

"It feels a bit like the early May bank holiday in the UK: cool, overcast, and a wind of about 20 mph. Murray won't mind."

2010: Federer 6-3 6-4 7-6 Murray

Eighteen months after defeat by Roger Federer in the 2008 US Open final, Murray reached his second Grand Slam final - again it was the Swiss superstar staring back from across the other side of the net.

This match was much closer but once again Federer proved too strong, although Murray blew five set points in the tie-break to go into a fourth set.

And defeat hit the 22-year-old Briton hard, as he broke down in his on-court interview. "I can cry like Roger, it's just a shame I can't play like him," he blubbed.

Andy Murray has already silenced the doubters, he can point to the two Grand Slam titles in his trophy cabinet. But what he has yet to do is show the world he can beat world number one Novak Djokovic in Melbourne Park. The top seed beat Murray in the 2011 and 2013 finals, so will it be third time lucky for the Briton or a hat-trick of victories for Djokovic against his old friend?

Hello! If you've been stuck in a cave for the last few days or, for a laugh, decided to stop communicating with the outside world, you may not know that Andy Murray has reached the Australian Open and, in just under an hour, will to toe-to-toe with his childhood friend Novak Djokovic in a mouth-watering duel for the title. This, in case you were wondering, is live text commentary of that match.

In the three million years or so that the varying versions of us humans , externalhave shuffled across this planet of ours, there have been many firsts; many remarkable feats achieved when history said it was impossible. "You're going to do what, Neil?" some would have sniffed in 1969. "Walk on the what? Talk me through it again..."

Back in 1903, the Wright brothers had dabbled and repaired and said they were ready to fly. "A machine? In the sky, Wilbur?" some would have sniggered. But if you tinker and fix and practice for long enough, you can achieve what once seemed unattainable.

And here we are in the beginnings of 2015, eyes fixed on a rectangular court in Melbourne, questioning, wondering... "Win the Australian Open, Andy? But you've lost the final three times. You've never beaten Novak in Melbourne?"
