Eight days, 15 hours, 13 minutes and 5 seconds.

That is how long separates us from the start of the World Tour Finals in London.

That is enough sofa time for Andy Murray to get his feet up, watch the Godfather, the Sopranos and every episode of Friends, and get in a couple of leg-loosening session with Amelie and Dani, before the traditional pre-tourney suited photocall with tennis fan David Cameron at number 10.

We'll see you there. Not Number 10, our invite got lost in the post. But back here on the live text.

Novak Djokovic speaking to Sky Sports: "We have played so many times. We know what to expect. It will be physical with long exchanges and whoever is calmer in the important moments and comes up with the big shots can prevail.

"He was a break up in the second, but he made some mistakes, made some double faults and allowed me back in. Then I was swinging through and I felt better.

"I don't think the physical factor played an advantage for me too much, but I think maybe winning the first set gave me an edge."

Less of my assessment though, what do the cold, hard numbers say?

Murray - Djokovic: Aces: 5-1, Double faults 3-1, First serve: 50%-63%, First serve points won: 67%-80%, Break-point conversion: 50%-30%

Adam Laycock:, external Murray going out not is necessarily a bad thing. Gives him a bit of rest before the O2 after a busy few weeks.

The main aim of Andy Murray's globe-trotting Eurasian adventure this autumn was to ensure a local and lucrative appearance at the World Tour Finals in November.

So, it has to be considered a success overall.

But today's defeat showed that, on current form, he is short of being a fully paid member of the game's very top set.

He's on the up though. Australia is going to be very, very interesting.

"The final point was a beautiful drop-shot from Djokovic - it feels like he's added so much more to his game this year under the tutelage of Boris Becker."

Andy Murray pats Novak Djokovic on the belly as they exchange post-match pleasantries. The Scot sorts his sweatbands at top speed, sweeping off court before Djokovic has even scribbled a smiley face on the camera lens.

It is either David Ferrer or Kei Nishikori next for Djokovic. It is home sweet home for Andy Murray.

Novak Djokovic wins the first point of the game to make it 17 out of the last 20. That is how quick the rug has been whipped out from under Andy Murray.

The Scot pumps a forehand long to give Djokovic 30-30, chops another into the net and finally folds out with running retrieve that can't make it over the wire.

"I think this match is over. It's been pretty grim this year in terms of this rivalry. Djokovic is running away with it now and it will be frustrating for Murray because they grew up together and he sees him as one of his peers."

Novak Djokovic presses the accelerator pedal on his steamroller, ironing out Andy Murray to love to move within a game of victory.

Andy Murray flops a tired forehand into the net to surrender his serve. And this time I fear that he may not relocate it in time to avert defeat.

The Scot's body language looks like that of a man who is imagining the sweet comforts of home rather than the challenges of the last four.

Remember that 90s toy Stretch Armstrong? He was a kind of rubber muscleman who you put on a radiator and could then yank his limbs across the width of a room.

I think he and Novak might be distant cousins. Normal service resumes for the flexible Serb as he holds serve commandingly.

Unfortunately for Andy Murray nailing Novak Djokovic to the board is like trying to arm-wrestle an octopus. After being defeated in the previous game, the Serb is back and bristling with renewed strength as though that set-back never happened.

He brings up 15-40 and two break points as Murray's pick-up half-volley creeps wide. Murray saves the first superbly, chasing hard, pinning Djokovic with angles and flicking away a fine mid-court winner.

He can't repeat the trick though. Murray into the net, Djokovic up on the board.

"The sequence of second serves are what did for Djokovic there. He didn't even manage 50% and Murray is lethal on the second serve because he comes in and mullers it on either side. His ability to pick up the flight is like a great batsman - someone like Tendulkar - and enables him to take the ball so early. He gambled, attacked, Djokovic gave him a chink, and Murray took it."

This match is teetering on the highwire at the moment. It feels like a short run of good points from either player would shift the momentum in their favour.

Andy Murray forces his first break point as he clambers into a return at 30-30. He allows Djokovic back to parity though with a strangled forehand into the net. Not a lot of pressure on the Scot either.

Djokovic's turn to get a little choky next though as he double faults to allow Murray a second bite at the cherry. And this time it sticks.

Murray chops and slices like a sushi chef, luring Djokovic into the net and edging ahead in the second set.

Six weeks of tiny hotel shampoo bottles, rubbery in-flight chicken and weirdly "freshened" taxi interiors. Is it all finally starting to catch up with Andy Murray?

The Briton's jet-set schedule looks like boomeranging back on him as he slumps to 0-40. He rouses himself though to climb out from six feet under. Strafing the Novak Djokovic baseline, Murray claims five successive points and completes an audacious escape from three break points down.

Djokovic is the one who finishes the game shouting in frustration, lobbing his racquet around and then apologising to the crowd who take a dim view of his shirtiness.

Novak Djokovic is serving like a machine. A well-built German machine. That comes with a 10-year warranty. That nobody bothers to register for because they know that they won't need it.

The Serb holds to 15 as he improves his first serve percentage to 74%. By contrast Murray's is down around 50%.

"I don't think Andy Murray can expect to win sets unless he is nailing his first serves better."

Andy Murray is in the vice at 0-30. Trying to get Novak Djokovic out of a rally is like trying to get grass stains out of cricket whites. You need some serious chemicals.

Murray shows he has the mix as he comes up with a whipped winner after a tentative overhead initially let Djokovic back into the following rally. A double fault follows though. 15-40 and two break points.

It would be an unanswerable break at this late stage in the set as well.

Murray wins a bit of netcord cat-and-mouse to see off the first, but finally the Briton is worn down by Djokovic's relentless precision. Into the net and Djoko, like the Mountie, has his man. And the set.

The first sighting of Boris Becker and Novak Djokovic's big-name coach is rocking the same trackie top he wore for his client's win over Gael Monfils last night.

Those sort of wardrobe repeats are inevitable when you are on tour. Especially with short-haul baggage restrictions.

Anyway. Djokovic's still serene on serve. Andy Murray ran down a drop-volley to flick away a crowd-pleasing winner, but still has not forced a break point in the match.

Fifty-eight minutes on the clock.
