Speaking of Ben Ryan. Here's something worth noting about the London-born Fiji coach.

He bans alcohol consumption during tournaments - and breathalyses his players to make sure they're not having a sneaky tipple.

Iron fist coaching, that.

See the red-headed chap at the back of this picture?

You've probably assumed he's not Fijian - and you'd be right.

He's Ben Ryan, the England sevens coach up until three years ago, and the man leading Fji's charge towards, what will now be, a first ever Olympic medal for their nation.

Ryan has coached Fiji to back-to-back World Sevens titles and he's somewhat of a celebrity ion the rugby-mad island.

Could he be set to scupper his home nation's golden hopes?

It was a colossal performance from GB against South Africa in the semi-final. They are excelling themselves. GB will be the second best team against Fiji but the have a real chance. 

The most important thing is to try and get rid of the atmosphere. It's another game of sevens. Fiji are not the quickest - they amazing footwork and skill. GB have more pace so there's various ways the can win it.

Also it's 10 minutes each way rather than seven so they can show they are fitter.

If we can keep the ball away from the Fijians we can definitely win it.

That was a demolition. South Africa run in eight tries to win the bronze medal, beating Japan 54-14. Rosko Specman scored a hat-trick and Cecil Afrika and a couple. Japan have Springbok footprints on their backs.

Next up, Great Britain v Fiji in the final...

High fives and fist bumps galore for Andy Murray and Heather Watson, as they clinch the first set 6-3 against Spain's Carla Suarez Navarro and David Ferrer.

However Jo Konta and Jamie Murray are trailing in their doubles match, after Americans Jack Sock and Bethanie Mattek-Sands took the first set 6-4.

Jason Kenny really looks in great form now and he has to be a favourite for the sprint. The keirin is a bit of a lottery but he has to be in with a shout.

Mr.T.Adams: 100% buying a bike tomorrow 🏅🚴

CerysHoops: Kenny Skinner Hindes. Not a small town law firm, but a winning Olympic cyclist machine. Yes boys!

Janine Pingree: I REALLY need to clean the parrot out but I'm addicted to #bbcrio2016 !!

Who's a stinky boy then?

Only Sir Steve Redgrave and Sir Chris Hoy have now won more gold medals for Great Britain than Jason Kenny.

Sorry, SIR Jason Kenny...

That was unbelievable. I know what it feels like to be in Callum Skinner's position and he dealt with it in great fashion. He's worked so hard to win his place in the team - he did that and there were all kinds of doubters.

I was fortunate enough to be inside the velodrome four years ago when British athletes won gold. It's a special atmosphere. Hot as a sauna, loud as a swimming pool.

That brings up a fourth gold medal for Great Britain at these Olympics. 

While Great Britain were winning gold in the veldorome, South Africa have been extending their lead in bronze medal-match. In scoring under the posts for the Springboks, Cecil Afrika even had time to ask the referee to pick up the hairband he dropped.

Job done for Pat McCormack, he's won his preliminary bout with Kazakhstan's Ablaikhan Zhussupov by split decision.

Next up for the Birtley boxer? The tournament number two seed, Yasnier Toledo of Cuba.

Steven Maden: They perform when it matters!

John: Philip Hinds is an absolute machine.

Matthew Pittam: Men's team sprint final was simply incredible. Don't think I breathed for the duration.
