You've got to be in it. You've got to put yourself in contention and Ben Pattison did that around the first lap and so he was just sitting there being patient, doing what we wanted to see.

I have to say I'm still a little bit speechless. He's 21 and hasn't been in this sort of calibre before but he kept his cool and he kept his form.

Ben Pattison is celebrating with his bronze medal around his neck. What a special, special moment.

We did not see this one coming for the 21-year-old.

There's that rapid finish I was on about!

Sensational from Ben Pattison!

He's got it!

Marco Arop wins it on his own out front but behind there's a four-way dash for bronze.

Great Britain's Ben Pattison thinks he's got it but once the result is shown on the big screen looks stunned.

Marco Arop goes from a long way out! Pattison is in there behind...

Ben Pattison finds himself in a great spot.

Pattison is second after a slow first lap.

It's going to be a dash for the line!

Ben Pattison is on the front early on. Highly-rated Kenyan Emmanuel Wanyonyi moves up alongside him...

Two laps sit between these eight men and glory.

On your marks, set, go!

With a Commonwealth bronze achieved on his major championship debut in Birmingham last year, Ben Pattison has managed to battle his way to the final at his first World Championships.

If this happens to be a tactical final, just watch out for the 21-year-old's trademark deadly finish.

A medal would be a massive shock - but you just never know in these middle distance scraps.

Ben Pattison snuck through to this men's 800m final as one of the two fastest losers.

On paper the Commonwealth bronze medallist Pattison is probably not one of the main contenders - he is one of two of the eight finalists yet to go under one minutes 44 seconds - but it is a wide open event.

19-year-old Kenyan Emmanuel Wanyonyi has been praised by the great David Rudisha, the world record holder of this distance, and is the fastest in the world this year.

Last year’s silver and bronze medallists Djamel Sedjati and Marco Arop have also looked strong.

Lewis Davey: "Personally I don't think my run was too great. I wanted a lot more from it."

Rio Mitcham: "We really mean business. We really want to get the job done. Just focus on this, focus on getting through to the final and that's what we've done so I'm happy."

Alex Haydock-Wilson: "I resolved within myself in that cool-room to trust these guys and they really did make my job easy for me. I can trust that they would give their all and if I'm trusting them, then I can trust myself too.

"When I got that baton, I just knew that I'd do whatever it took to get us in that final. Tomorrow I'm going to have the same mindset. I'll do whatever it takes to get us on that podium."

You can't have a relay-filled session and not have any drama, right?

It's the USA who suffer the first high-profile disaster of the evening after that messy changeover - bumping Italy up to the automatic qualification places to big cheers in one section of the crowd.

Great Britain beat USA there anyway but now the defending champs are out.

That really does open the door for the British quartet in tomorrow's final.
