A dramatic and memorable night at London Stadium for several reasons!

We shall leave you now, a delayed Match of the Day is about to start and you can watch online.

Join us Sunday night for the finale. See you there!

Jamaica's Julian Forte speaking to IAAF radio about team-mate Usain Bolt's injury: "He didn't tell us exactly what happened but from what I saw, it looked like a strain or a cramp of some sort.

"He kept apologising to us but we told him there was no need to apologise - injuries are part of the sport."

The time of 37.47 by the British team was also a European record, beating the time of 37.73 that had stood since 1999.

CJ Ujah: "I am proud of these guys and those behind the scenes. It is crazy to do this in London. I can't even talk right now."

Adam Gemili: "We are World champs! To run it with Danny Talbot after such disappointment in London 2012, it is so special to come back. Thank you to everyone. It's crazy. Honestly a dream and a reality tonight. Wow!"

Danny Talbot: "2012 didn't go our way and we have been working hard since then. It's a massive team effort and we win as a team and lose as a team. We are world champions at home. We will never get this feeling again."

Nethaneel Mitchell-Blake: "I wasn't sure if I had won or not, I gave it my all but I could see Christian Coleman out of the corner of my eye. The feeling of euphoria was from infinity. I can't register it. We smashed the British record to pieces."

Bolt did not want to leave in a wheelchair did he. He refused to leave in that way and that's right - he should never have to finish like that.

Champion Kevin Mayer: "I am so, so tired. I cannot even imagine I am the world champion.

"I just want to say this is the most amazing public in the world."

It's easy to say now, and hindsight is a wonderful thing, but should Usain Bolt have retired in Rio?

Jamaica and Usain Bolt had won the last four 4x100m relays at the Worlds, that's Britain's first ever title.

It's four for Jamaica, one for France, one for South Africa, two for Canada and seven for the US.

An amazing and outstanding performance from that British team. They beat everyone fair and square.

They delivered on a night when everyone was here - not necessarily to see this.

Adam Gemili was just ridiculous down the back stretch. He opened up a gap that was always going to be hard for anyone to chase down.

That is a near-perfect display from the British sprint quartet - CJ Ujah with phenomenal reaction time of 0.124 secs, Adam Gemili brilliant second leg after injury-wrecked season, Danny Talbot with flawless bend, Nethaneel Mitchell-Blake holding off the 100m silver medallist Christian Coleman and finishing with a beautifully timed dip.

That's how records and gold medals happen.

Mitchell-Blake doesn't look left, doesn't look right. He just focuses straight ahead.

A gold and two silver medals for Great Britain in the space of a few hours. And that doesn't cover the half of it.
