Have you seen anything like it...?

The extraordinary moment GB's men's four almost crashed!

Andy Murray and Joe Salisbury had never played doubles together until this Games. You wouldn't have guessed it by watching them.

Of course, Murray is a three-time Grand Slam singles champion who has had ATP/Davis Cup doubles success, while Salisbury is an Australian Open men's doubles champion.

So, perhaps it is not so surprising that two players of this talent have dovetailed nicely.

And the British pair are already ahead in the early stages of their quarter-final against Croatia's Marin Cilic and Ivan Dodig. A break in the first game of the match gives them the advantage.

Slowly waking up and your bleary eyes need an at-a-glance summary of what has happened overnight? Gotcha.

• Swimming: Great Britain's men win a superb gold medal in 4x200m freestyle relay, narrowly missing out on a new world record.
• Swimming: America's Katie Ledecky claims a sixth Olympic gold with victory in the 1500m freestyle.
• Swimming: Australia's Ariarne Titmus beats Ledecky in the 200m freestyle, securing a 200m-400m double for the 20-year-old.
• Rowing: Great Britain win their first Olympic medal in the men's quadruple sculls.
• Rowing: Britain's dominance of the men's four ends as their crew veers off course and is unable to win the nation's sixth straight Olympic gold.
• Men's rugby sevens: Britain drop into bronze medal match after 29-7 defeat by New Zealand in semi-finals.
• Hockey: Great Britain women's team continue the defence of their title with a convincing 4-1 victory against India in Pool A.

There was no doubt in two-time Olympic champion Adam Peaty's mind that medal success in the pool was written in the stars for GB.

To be a length up and to still lose it is a kick in the teeth. They did right the wrongs of the heat and they are in the final, but an outside chance.

Some good news for Great Britain in the rowing. And to be specific in the men's eight.

They are through to the final after finishing second to New Zealand in the repechage.

Good job those bikes are relatively light! Who has the energy to do that after a lung-busting half an hour on the saddle.

Chris Quinn: Can we please talk about that leg by 18-YEAR-OLD MATT RICHARDS, please?! WOW. Sensational.

Elizabeth Macpherson: I think I've woken my neighbours up! Swimming 400 m! GOLD!!!

Nicki French: Now THAT was worth setting the alarm for! FANTASTIC work by our 4 x 200m swimming medley team - over THREE secs faster than 2nd place! So well deserved. Proud!

Another one in the bag for Germany.

As the timer in the second quarter ticks down, Cecile Pieper adds the finishing touch to Kira Horn's powerful cross.

Ireland just can't seem to find a way through that German defence.

Tom Dean: "I can't put this into words. I couldn't yesterday. I can't thank these boys enough.

James Guy: "As a kid dreaming of an Olympic gold medal was my dream. After 25 years to do it finally, it’s very emotional. With these four we have the best freestylers in the world. It’s a dream come true."

Matt Richards: "When you’re racing with guys like this, having a great leg comes easy. When you know you have one of the best freestylers in the world going after you it gives uyou confidence. money can't buy it.

Duncan Scott: "For myself and Jimmy in particular we’ve been on so many 4x200s together. I think this is really special with those boys. Matt in third was so composed. So close to the world record, if anything I am bit gutted we didn't get it."

Great Britain haven’t won a medal in the mixed doubles since Gail Emms and Nathan Robertson took silver in Athens in 2004.

Unfortunately, that's not about to change anytime soon.

Marcus Ellis and Lauren Smith's hopes of securing a medal at Tokyo 2020 have come to an end at the quarter-final stage.

The pair have been beaten 21-13 21-18 by Tang Chun Man and Tse Ying Suet of Hong Kong.

The player to beat in tennis's women's singles? Certainly seems so.

Ukrainian fourth seed Elina Svitolina - the highest-ranked player - is through to the semi-finals after a straight-set win against Italy's Camila Giorgi.

Next up for Svitolina will be Spain's Paula Badosa or Marketa Vondrousova of the Czech Republic.

Sam Tilley: Oh my word what a swim!! Heroic from all four swimmers.

Surviving2021: What did they have for breakfast.

Jude Torpey-Aldag: Yessss get in there. Staying up for the Olympics and seeing a gold is as good as it gets.

Anyone else remember the days when we could barely win a medal in the pool. This is the first time GB have won three swimming golds since 1908.

It was a demonstration at the end. I so wanted them to get the world record - but they will get it, because it is a young team.

What a mature performance.

We're back on the south pitch at the Oi Hockey Stadium for the second match in Pool A.

And it's not the best start for Ireland.

Germany's Lisa Altenburg latches onto a long pass, she weaves round the Irish defence and drives home the opening goal for the Rio bronze medallists.

Adam Zimmer: BOOM!!!

Miss A: Yes!!! Worth staying up for.

Natalie Lewis: What a swim from the four guys, Wow.

When you give it to Duncan Scott to bring it home - look at the distance we won it by!
