Coleman has a bright future. It was a long season for him and this was probably one race too many. He has turned professional and has a bright future. He is also a very good 200m runner.

Justin Gatlin is 35. He may decide that this is the end of him as well as Usain Bolt.

This will be really difficult for the sport. Russia has been expelled indefinitely from the sport, but Gatlin has been banned twice and here he is winning gold in the most precious event in the sport.

The crowd perhaps ought to be booing the IAAF rather than the athletes.

If you couldn't take it in the first time, it is worth a re-run.

To paraphase Sir Alex Ferguson; sport, blinking heck.

You have to give Justin Gatlin credit. He lost the 100m title last time around but this time he wasn't worried abut anyone else because he was in lane eight. He has learnt from that mistake.

The immediate reaction of Usain Bolt and Justin Gatlin after the finishline was interesting.

Gatlin jeered throughout the competition, initially exploded with defiant joy and put his finger to his lips.

But he changed tack pretty sharpish, bowing down to Bolt.

Bolt himself was magnanimous, offering his immediate, genuine and smiling congratulations.

There is not a feeling of disappointment. We all wanted Bolt to win but he always entertains us. He will be happy. He has had an amazing career. For us to witness this is amazing. It is not gold but it remains amazing.

Bolt's reputation as the greatest sprinter of all time is secure. His body has been at this for half of his life and this is the one occasion where he could not shake off the injury. The times in previous years would have been well within his reach but his reputation will not be in question despite this.

2015 was supposed to be Gatlin's year to dethrone Bolt. He's been booed through every round here. And now the man banned twice for drugs has taken his revenge. A party has officially been pooped.

Susan E: Gutted for Bolt but he'll always be the #GOAT, external - Coleman is definitely one to watch for the future

Richard Afrifa: Gutted for Bolt that he couldn't go out with Gold, but what an athlete! Legend!

Susan C: Well that was a shock. Oh dear. But that is sport.

1. Justin Gatlin 9.92

2. Christian Coleman 9.94

3. Usain Bolt 9.95

You need some things in black and white and in triplicate.

We have to suck it up and see. We have had a fantastic championships but now all the talk will be about Justin Gatlin.

I thought Bolt would be challenged but by Coleman not by Gatlin. Bolt was under pressure. He didn't have to be here and you have to give him credit for putting himself out there and give people the chance to beat him. Two did beat him and I'm sure people are upset. I can guarantee you Bolt will not be upset. He is a competitor but he realises that life goes on.

Usain Bolt ends his individual career with a bronze medal,

Christian Coleman took silver just ahead of him.

Justin Gatlin's winning time was 9.92.

Usain Bolt was finishing fast, but just left himself with too much to do - and he has to settle for bronze behind Christian Coleman.

London Stadium is initially in shock, but has turned this into what they wanted anyway. Usain Bolt is heading around the stadium to an ovation as if the previous 10 seconds never happened.

Confusion as Justin Gatlin, Usain Bolt and Christian Coleman converge on the line as one.

A look up to the screens.

And it is Gatlin.

The crowd jeer and he shushes them with a finger to his lips.

Su, Vicaut, Bolt, Simbine, Coleman, Gatlin, Blake, Prescod.

Here we go.

Usain Bolt gurns as his face appears on the big screen.

He strolls up the home straight, taking it all in before flashing his index fingers in the air to acknowlege his public.

Christian Coleman is not clowning though. He could not look more business like if he had come out in a bowler hat.

Each of the men's 100m finalists gets a personal introduction, running out from behind a sightscreen and into the cauldron of noise.

Reece Prescod is first out and gets a hearty cheer.

Usain Bolt is last out and gets the full Spinal Tap 'turn it up to 11' reception.

I think what we are about to see is a fantastic competition. People come to see Bolt because he is a legend. Coleman can challenge Bolt but Bolt looks ready. He is not going to be at that 9.60/9.70 second range. He is going to be around 9.80.
