Stats can mean whatever you want them to mean, so they say. But, from what we've seen so far this week, we know Viktor Troicki has an ace or two up his sleeve, with the Serb serving a whopping 43 so far on Queen's lightening-quick courts. Other statistics are available, of course. Murray impressive on his own serve, holding to 15 without fuss.

"Troicki has a great first serve and he's quick. He's a great athlete and tall at 6ft 4in, much like Andy Murray, so we should a lot of extended rallies. He will be no pushover that's for sure."

George Sim: Well patently obvious that there's no love lost between Muzza and Troicki. Could be an interesting match!

Bob Dutton: A tough test for Andy Murray this afternoon, he's a good player Troicki. Just hope the weather holds.

It's the Serb who is serving first and he easily collects the opening two points, easing to 30-0 with a crisp drilled backhand. The underdog's movement a little statuesque on the next point, though, and he biffs a backhand into the tramlines. Murray at the net. Murray winning at the net. "Come on," whispers someone in the crowd. 40-30. The Troicki serve under pressure. Actually, scrap that. Murray slaps a backhand into the net and Troicki wriggles free.

"Andy Murray is moving well and striking the ball well too. His first serve also seems to be more consistent. There are a lot of things going in his favour."

Actually, Mr Mourinho is at Queen's Club today and has been entertaining us with a fine display of facial expressions.

Yes, the picture above does look like Andy Murray has stolen a Jose Mourinho waxwork from Madame Tussauds - but the Chelsea manager has been a regular at Queen's this week so the picture the British number one posted on his Instagram , externalaccount is probably (most definitely) one of himself with the living and breathin' Special One.

"I haven't spoken to him long enough, but I'd like to" said Murray on Friday of his encounters with Mourinho.

"Hopefully Jose will be back at Queen's over the weekend and I'll be able to produce the goods again. And if he's ever looking for a few more goals, I normally play up front.

Some of you are probably scratching your heads, raising a furrowed brow in an attempt to remember all those facts you learned about Viktor Troicki back in the days when knowing all about the 6ft 4in Serbian was the ultimate party trick. It was, wasn't it?

The 29-year-old has recently moved up the rankings to 25th in the world and has won one title this year. In Sydney.

And although he shouldn't pose too much of a problem for Murray on grass, he did reach the Mercedes Cup final last week where he was beaten in straight sets by Rafael Nadal. He's in form, but is that good enough to beat the third best player in the world?

Andy Murray has beaten his Serbian opponent in their six previous encounters - but they've only met once since the Belgrade-born right-hander returned from a 12-month ban last July for failing to take a doping test.

Back then the Scot described Troicki's conduct as "unprofessional" and Murray stood by his comments on Friday.

"Obviously you have to be aware of what exactly the rules are," Murray said. "Like I said, it's extremely serious. If you want to protect the image of your sport, you need to understand how serious the drug testing is and anti-doping is."

As our resident Queen's Club weatherman Piers Newbery alludes to, Kevin Anderson is the man Andy Murray will face should he reach the final. The beanpole South African beat Gilles Simon 6-3 6-7 (6-8) 6-3 and did so with a stylish ace, his 34th of the match. The rapid courts of West London were made for big servers.

By the way, Murray and Troicki have appeared on court, gone through the routine of the coin toss and are currently warming up.

"We have already had one shock today as the light drizzle abated long enough to see the first semi-final completed. There had been hushed talk in corners of possibly moving Anderson v Simon to the non-televised Court One, should the weather window open for just a couple of hours, and playing both semis simultaneously. The South African has safely booked his place in the final, however, and can now wait to see whether he has an opponent by the end of today. It's currently an autumnal 18C, grey overheard, with a fresh breeze and predictions of rain on the way."

Hello! Welcome to live text commentary of Andy Murray's semi-final against Viktor Troicki at Queen's Club. Thanks for joining us.

There are plenty of numbers for us to grapple with because should Murray win today he'll remain on course to secure a fourth Queen's title. Victory over Troicki would also ensure the Scot reaches his 50th Tour final and fifth final of the season so, really, 50, five and four are the magic numbers.

As we all know, in De La Soul's lesser known remixed single they said four was indeed the magic number. And as has been widely reported over the years, Enid Blyton wanted to write about the Famous Four, external but suffered from dyscalculia. Yep, all good things come in fours. Definitely.
