Rita: Absolutely love the four girls in GB's gymnastic team. Four young stars. Huge congratulations to them for winning bronze, what a performance, Fantastic!
Aly: Well thanks Team GB, I'm crying after that interview
Image source, BBC SportThis is how the medal table looks with hosts Japan leading the way thanks to their 10 gold medals, closely followed by the United States and China.
Great Britain are fifth with four golds, five silver and four bronze medals in the bag.
Not a bad start at all.
Matthew Lowson: Magic Monday has been followed by Tremendous Tuesday! Wonderful Wednesday to follow????
Let's hope so Matthew!
BBC Sport caught up with the 'awesome foursome', our bronze medallist women's team.
On what the medal means to them, Jessica Gadirova said: "It's a dream we never thought could come true, I never thought it was possible but today it happened!"
Her twin Jennifer Gadirova added: "It's more than a dream come true really! It's just incredible. we are such an amazing team and I think without each and every single one of us working hard and our performances it wouldn't have been possible. I'm so thankful for all of you guys and so proud of all of you!"
Simone Biles, who pulled out of the gymnastics team final earlier, just spoke to BBC Sport.
"I'm just dealing with things internally that will get fixed in the next couple of days," she said.
"It's made us stronger for sure."
When asked if she would return for Thursday's all-around final, Biles replied: "Yes."

Scott Cain: Brilliant swim by Team GB in 4x200m relay, swimming final tomorrow hopefully another gold
Verity Stevenson: Bronze number THREE today won by Charlotte (human) and Gio (horse)!
Davestwin7: Got to love being late to work as I was watching Charlotte Dujardin and Gio.
Image source, InstagramFail to prepare, prepare to fail. Tom Daley has certainly come ready. The 10m syncro champ, along with Matty Lee, has knocked up a little knitted gold medal case to stop that precious metal getting dinted and dented.
When you have worked so hard for it, it makes sense to look after it.
In other news, Andy Murray has developed a hobby at the Olympics - running around collecting pins from other athletes.
“I’ve always enjoyed doing that all of the Olympics. We’ve all been in a bit of a competition," he said.
"We haven’t been given that many pins to exchange, so I’ve been trying to do pins for selfies’ to gain a bit of an edge.
“You end up meeting some interesting people. I met two Syrian brothers, one who’s competing for Syria and one for the refugee team.”
“You meet people from all different backgrounds and that’s one of the things I love about this competition. It brings people together from all over the world, from all different backgrounds. It’s brilliant, I love it.”

Women's team final
Beth Tweddle
London 2012 bronze medallist on BBC TV
The work that has gone in behind the scenes for this team and the 18 months they have gone through.
They were 12 weeks out of the gym completely, when we know some of the other countries were still in the gym training.
Ups and downs with trials behind closed doors so they've really had to adapt to the new world.
I'm speechless!
I felt sick towards the end because I could see they were so close and I just thought you can do this.

Prior to the Tokyo Olympics beginning, our Virtual Medal Table, external forecast 52 medals for Great Britain including 14 golds.
After four days, the expectation was that Great Britain would have 10 medals - three gold, five silver and two bronze medals.
Team GB actually has 13 medals - four gold, five silver and four bronze medals.
The forecast for Great Britain has therefore improved to 55 medals including 15 golds. This is likely to be enough for fifth place on the medal table on both total medals and gold medals.
Women's team final
Wonderful scenes, as Team GB's young quartet receive their bronze medals. A tremendous effort.
