Former coach to Andy Murray and Laura Robson on BBC Radio 5 live sports extra

"It will be pretty calm in Andy Murray's dressing room. You still have the coin toss and knock-up to go and if you come out on court too psyched up then you are going to hit a bit of a lull.

"Most coaches will go through some of the key points which they will have outlined the previous night."

When does a rivalry lose its edge?

When one of those competing has won the last seven encounters?

Or 10 of the last 11?

That is the hold that Novak Djokovic has had over Andy Murray in their recent meetings.

On the bright side, Andy Murray's only win over Novak Djokovic since the 2012 US Open was that unforgettable Wimbledon final of 2013.

Cheers Jonathan.

What we need after that see-sawing epic is some light relief.

Who have we got waiting in the Philippe Chatrier wings?

Doubles duo Mansour Bahrami and Henri Leconte? A knock-up between Tim Henman and John McEnroe?

Oh no. Deep breath. Andy Murray v Novak Djokovic is next up - we are going in.

One down, one to go. So the identity of the first men's singles finalist has been unveiled. A Swiss chap going by the name of Mr S. Wawrinka.

But who will join him? World number one Novak Djokovic? Or British number one Andy Murray?

Those two will step out into the Court Philippe Chatrier sun very shortly. And that means it is time for my doubles' partner Mike Henson to serve up...

"There's not much doubt that 1/17 will be the figure that sticks in the mind from that match for Tsonga - 16 chances to break that came and went. He's not the only man to have suffered in that way on Court Philippe Chatrier, with Roger Federer also going 1/17 in the 2007 final against Rafael Nadal.

"Rog achieved his dream of a French Open title two years later, so maybe there is still hope for Jo."

Jo-Wilfried Tsonga, who we must remember has struggled with injury recently, receives the kind of acclaim reserved for a hero as he trudges out of Roland Garros for another year. Wawrinka played some excellent tennis, but Tsonga will rue that lorryload of missed break points.

A victorious Stan Wawrinka points to the side of his head as the Swiss eighth seed receives a mixed reception from the Court Philippe Chatrier crowd. Not sure exactly what that means. "Think about your reaction," perhaps? Obvious disappointment from the Parisian fans, including a few boos, as their wait for a first men's singles finalist since 1988 goes on.

All over! Switzerland's Stan Wawrinka reaches his first French Open final after seeing off the great home hope.

Hope for Jo-Wilfried Tsonga as he leads 15-0. Brief hope as it turns out, Wawrinka crashing down a couple of 220km/hr serves which Tsonga can't return, before he slows his serve down to catch out his opponent and set up two match points. The Swiss man takes the first as Tsonga lazily clubs his serve into the net.

Tsonga blasts down an ace to seal the ninth game of the fourth set - and keep himself in this match. But, in anything ranging from two to eight minutes, he could be out of Roland Garros. Stan Wawrinka is serving for his first appearance in the French Open final....

From a marathon to a sprint. Wawrinka does not want to hang about any longer, sticking his foot on the gas to go from nought to 40 in a matter of seconds. Game over as Tsonga serves to stay in the match...

Rhys Hopkins:, external "Wawrinka v Tsonga is an engrossing match. Great tennis being played, but Tsonga has been wasteful with break points."

This is a marathon game. The longest of the match no less. That dropshot sets up another game point for Tsonga. And guess what? Yep, he blows it with an unforced forehand error. But the Frenchman bounces back and takes a gutsy - and much-needed - hold.

Failure to hold serve here and Tsonga may as well say bonne nuit to Roland Garros for another year. Wawrinka takes a lesson from the Tsonga-written 'how not to convert break points' instruction manual, wasting three golden chances of a double break.

However, the third goes down to pure brilliance from Tsonga, who almost nonchalantly spins a beautiful drop shot millimetres over the net. That turns the tide in the Frenchman's favour...

Dave Wilson: "Considering what is happening between Tsonga and Wawrinka and the weather threat, perhaps they should have started Murray v Djokovic on Lenglen and switched the second ladies doubles to Chatrier.

"Would be a real shame if the Murray match doesn't end today. Big disadvantage you would think."

Wawrinka serves as the sun continues to shine down on Court Philippe Chatrier. For now at least. The eighth seed has a brief moment of concern at 40-30, but eases any lingering tension with a smart backhand volley.

"On a sunny evening you can play until about 21:45 local time (20:45 BST) in Paris. But if the clouds roll in then, the light would die away well before that."

"I was speaking to someone in the canteen who said that once it starts raining it won't stop this evening. If that is the case, then it is likely that Andy Murray against Novak Djokovic will almost certainly finish on Saturday.

"If the rain does prevent Murray v Djokovic reaching a conclusion, the organisers will put the conclusion of that semi-final on a before the women's final tomorrow, probably at 12:00 BST."

This inability to take any of these break points must be soul-destroying for Tsonga. More soul-destroying than asking someone attractive you fancy for a telephone number and being rejected.

But the Frenchman quickly regains composure. With the ball in hand, he opens up a 40-0 advantage and, despite a couple of blips, thumps down a forehand winner to hold.

Back to the ridiculous from Wawrinka as he goes wide with a seemingly straightforward backhand. The Swiss saves another break point with his 15th ace of the match, then saves two more break points as we go to a fifth deuce. Anyone fancy taking this game by the scruff of the neck? Stan does. He targets the Tsonga backhand again and two errors give Wawrinka a crucial hold.
