The shape of Australia, they play with a 3-4-3 and they will try to overload you down the sides. I think Rachel Daly is athletic and defensively solid to try and nullify that.

She can help stop the crosses coming into the box that will help stop the threat of Sam Kerr.

Equally she can run you the other way, I don't think she has the natural attacking presence of a Nikita Parris or Fran Kirby but a very, very solid player.

Australia have started brightly here. The Matildas have a free-kick on the halfway line. Emily van Egmond spots the run of Sam Kerr and launches the ball forward, but it runs all the way through to Ellie Roebuck.

Novak Djokovic ain't going to have this all his own way.

Germany's Alexander Zverev is now in his stride after losing the first set 6-1 and has just broken the Serb in the second.

He'll now serve to level things up. This would be the first set the world number one has lost in Tokyo.

Keira Walsh gets a shot on target under her belt. She does well to curl an effort after it bounced awkwardly in front of her. It looks like it takes a slight deflection but Teagan Mica has it covered.

While Great Britain's footballers get underway in last eight action, there may be a slight delay in their Sevens counterparts doing the same.

They were due to play the United States at 10:30 BST but there is a risk of lightning in the Tokyo Stadium area.

We'll let you know when they are back on track.

Sam Kerr and Steph Houghton will be the battle. Kerr will probably play on Leah Williamson

Kerr has three goals already. That is the big threat GB have to defend against and they need to keep her quiet.

Here we go. Can Team GB reach the Tokyo 2020 women's football semi-finals?

Australia stand in their way.

GB take the knee before Ellen White gets us under way.

I think Team GB have been magnificent in the group stages. They have been dominant and have looked in control and focused.

Internally in the camp they have a real strong belief and they are very confident going into this game.

It is history in the making for these women.

You can't underestimate Australia, they have got better and better and better the Matildas. They currently have eight players who play in the WSL so they will be well known to the GB players.

It will be a tactical battle for Hege Riiise, I think it will be a cautious start and by the end it will be full on war.

Victory for Team GB over Australia today would see them better their result at London 2012 where they were knocked out by Canada in the quarter-finals.

If they win, GB will face either Sweden or Japan in the semi-finals, avoiding both European champions the Netherlands and world champions the USA until the final.

There's plenty of familiar faces in the Australia starting XI who play GB shortly, with several playing in the WSL.

Chelsea's Sam Kerr is the big name. She captains the Matildas and will play in attack alongside Arsenal's Caitlin Foord.

Steph Catley, also at Arsenal, Everton's Hayley Raso and West Ham duo Emily van Egmond and Tameka Yallop start too.

Swimmer James Wilby paid an emotional tribute to his mum, calling her his role model after finishing sixth in the men's 200m breaststroke final.

The 27-year-old swimmer said he was disappointed he could not reward her sacrifices for him with an Olympic medal.

Speaking to BBC Radio 5 Live, James’ mum Fiona said his words made her cry.

“I do have a close relationship with him, but I didn’t realise it meant so much to him”, she said.

“Am I disappointed with sixth? Absolutely not. I’m super, super proud of him… he’s made two Olympic finals, what more could you ask for?”

Team GB get their women's football quarter-final under way shortly when they take on Australia.

The winner of that match will play either Sweden or Japan, who kick-off at 11:00 BST.

Canada and Brazil remain goalless in the first match which is going ahead, while European champions the Netherlands take on world champions the United States in a mouthwatering clash at 12:00 BST.

What a great little video this is.

Kye Whyte had won his silver medal 20 minutes before, but made sure he was right on the finish line to scream Team GB team-mate Bethany Shriever to gold in the women's final.

Olympic gold medallist Bethany Shriever's mum Kate Shriever on BBC Radio 5 Live: "To win gold is just a dream come true. I think it being quick is quite good, the risks are quite high. We are nervous for her safety, we just want her to get round without coming off.

"It was emotional, there was not a dry eye in the house."

"She literally put everything into it, she knew there was someone behind her. She gave it absolutely everything she had.

"I think it was all worth it when she got the letter to say she was going to the Olympics. Anything after that was a bonus, she just wanted to race and enjoy the experience. She has loved every minute of it. We all knew no matter what the outcome was we would be 100% proud of her.

"The only time [she needed pushing] was after she broke her tibia and fibula twice. Her first session back after the first break, she landed a jump and on impact the metal rod in her leg bent and shattered her leg again.

"A lot of people had written off her at that point, she was a really good rider but to break her leg twice and be out of the game for about 18 months, but she was determined afterwards.

"Although she is the only female on team GB for British BMX the support she has from Kye is just a lovely thing. She has been so happy the last couple of weeks and the whole experience has been so amazing for her.

Novak Djokovic is making fast work of his semi-final with Germany's Alexander Zverev.

The world number one broke the fourth seed's serve twice to win the first set 6-1 in 37 minutes.

Here is a little video refresher of what has gone before in Tokyo....

There was gold for Beth Shriever in the BMX

There was silver for Kye Whyte

And bronze for Bryony Page.

Team GB

Team GB women's football head coach Hege Riise: "It's been a privilege, we have been working on the culture, who are we, how we want to be seen, how we want to perform.

"All the players buy into that, they know what it will take for us to go all the way.

"I feel we have done a great job. Now it's the knockout stage and it's about how brave we are.

"I feel we are in a good spot right now, the players feel comfortable, they feel we are doing the right things. I'm excited for the game."

After Mallory Franklin's silver on Thursday, Great Britain's Bradley Forbes-Cryans couldn't quite get onto the canoe slalom podium, finishing sixth.

Forbes-Cryans qualified for the British team ahead of Rio 2016 champion Joe Clarke.

Boxing Olympic gold medallist on BBC TV

Boxing always contributes a lot of medals to Team GB - they're a real force the set-up that they have, the EIS in Sheffield is unbelievable.

I've seen Caroline Dubois on the pads and training, she hasn't had that many fights, but she's only lost one. There's a lot of talent to come and a lot more medals to come from Team GB.

Boxing is probably one of the hardest sports to actually qualify for the Olympics.
