Mattia Furlani was always told as a youngster that he has potential.

But sometimes that can be tough on you. Having potential is one thing but converting that is another thing entirely.

It's gold for the 20-year-old Mattia Furlani of Italy!

His closest challenger Tajay Gayle of Jamaica can only manage a final jump of 8.09m so Furlani's fifth round 8.39m is enough for the win.

Yuhao Shi of China takes third.

Josh Kerr is a man who leaves no stone unturned. He has practiced driving into the stadium from where the athletes warm-up. Of course he has.

The athletes have to report 50 minutes before the race begins. They need to make sure they are splitting their warm-up. Half in the warm-up stadium and half in the national stadium.

You do have a different mindset when you are the defending champion, knowing that you have won and the pressure and expectation of doing it again.

The hardest thing for an athlete is maintaining standard.

In my experience, I felt that pressure and Josh [Kerr] will be feeling the same.

Team GB's Josh Kerr and 1500m defending champion speaking to BBC Sport: "I am excited to go and retain. My main aim is to retain my title. I believe truly and deeply that I can and it's that or it is a failed day.

"It is about making sure you are winning your one percents. As long as you feel like you are one step ahead of your competition, that's huge.

"I know the way that I approach a day like this. When I step up to that line, I know there are going to be a few athletes capable of winning that gold.

"But I am a well-rounded individual and I am going to try and win my one percent battles.

"I am never disappointed when I know I have given full effort and left no stone unturned. I can only affect what I can affect.

"I truly believe that I am still the best in the world."

I have no idea what is going to happen today.

It is the first time in a few years that we have not had Jakob Ingebrigtsen as a pacer, which will be strange.

We had two really messy semi-finals. It was as if people didn't know what to do, including Josh Kerr. That might play on Josh's mind.

Jake [Wightman] has a great practical brain if it is slower, but Josh will be hoping for it to be paced as fast as possible.

Hopping back to 2023 again, our pundits at the world championships in Budapest compared Josh Kerr and Jake Wightman's respective wins in this event.

Jake Wightman was the man to beat Jakob Ingebrigtsen in 2022, taking gold in Eugene.

Wightman won in 3 minutes 29.23 seconds, 24 hundredths of a second in front of the Norwegian, while Josh Kerr finished fifth.

As we build towards the men's 1500m final at 14:20 BST, let's take a bit of a look back at how defending champion Josh Kerr won in 2023.

With his injured compatriot Jake Wightman absent, Kerr beat his rival Jakob Ingebrigtsen in Budapest in a time of 3 minutes 29.38 seconds - 27 hundredths of a second ahead of the Norwegian.

A host of big names will be absent from the start line.

Former Olympic champion and two-time world silver medallist Jakob Ingebrigsten failed to progress beyond the heats, with Phanuel Koech exiting at the same stage.

Olympic champion Cole Hocker (USA), meanwhile, was disqualified from the final for jostling in his semi-final, with Germany's Robert Farken promoted in his place.

Netherlands' Niels Laros beat Josh Kerr and Jake Wightman in the first semi-final and won the 1500m at the recent Diamond League finals in Zurich.

Kenya's Reynold Cheruiyot, a former World Under-20 champion, came out on top in the other semi-final, ahead of Spain's Adrian Ben and Portugal's Isaac Nader.

The fact that Cole Hocker is no longer in this final, it will feel different for Josh [Kerr].

He wants to be the best in the world and he is so measured and so focused on every little detail.

He will have been disappointed in Paris to get silver, but his mentality to turn that into motivation for what he wants this year - it is so impressive.

No medals in the first four days, when 31 other nations have already managed to get themselves on the board, doesn't look great for GB - on the surface at least.

They would have liked to have got up and running at the championships with a medal in the mixed 4x400m relay on Saturday.

Since then, an unfortunate injury to pole vaulter Molly Caudery, marathon runner Emile Cairess' struggles in extremely challenging conditions, and an early exit for an out-of-sorts Matthew Hudson-Smith have dented GB's medal hopes.

But, set a target of a top-eight finish in the medal table, there are plenty of members of the British team with their podium ambitions in tact - not least 1500m trio Josh Kerr, Jake Wightman and Neil Gourley in today's final (14:20 BST).

Olympic medallists Keely Hodgkinson and Georgia Hunter Bell will hope to achieve a one-two in the women's 800m, Katarina Johnson-Thompson is the defending heptathlon champion and there are four more relay medals to fight for, to name a few opportunities.

At this stage, one gold is good enough for seventh place in the table. Let's hope for a strong finish.

You may be wondering why we haven't seen any medal ceremonies so far at this world championships.

While winning athletes are quickly handed medals after their race or event has concluded, the podium ceremonies generally don't take place until the following day.

This is when the athletes receive their official engraved medals and the national anthem of the gold medal winner is played.

There is a dedicated 'medal plaza' next to the Japan National Stadium that hosts the ceremonies.

Members of the public are able to attend the ceremonies - organisers say the format gives more athletics fans the chance to be part of the events.

We're through four attempts and there's been a shock in the men's long jump final.

Favourite Miltiadis Tentoglou of Greece is out, one of two athletes knocked out at this stage, having managed a best of 7.83m.

Mattia Furlani of Italy, the Olympic bronze medallist, has just taken the lead early in the fifth round with a personal best distance of 8.39m.

He's just 20 years old.

Could the wait for a British medal soon be over?

Well, with defending champion Josh Kerr and 2022 champion Jake Wightman in the 1500m final alongside fellow Scot Neil Gourley, you'd say there's every chance!

After his heat, Kerr said: "I am coming here as someone who's done it before and I am coming to do it again." And he followed it up by finishing second in his semi-final in a time of 3:35.53.

Wightman came third behind Kerr in that heat but has played down his own chances following a run of injury struggles. He is "not putting too many expectations" on himself but looked comfortable throughout his semi-final and has a season's best time of 3:31.58.

As for Gourley, he earned his first global medal when he finished second to Jakob Ingebrigsten at the World Indoor Championships in March. He will be looking to improve on his ninth-place finish in Budapest in 2023.

Katie Moon's expression was absolutely priceless as she hit the mat and looked up at the bar, her mouth wide open.

Knowing full well she's caught it, she watches in disbelief as it takes an eternity to resettle into position.

A third consecutive world title, by the barest of margins.

Three of the four fastest women in history are in competition in the women's 3,000m steeplechase.

Winfred Yavi of Bahrain, Uganda’s Peruth Chemutai, and Kenya’s Faith Cherotich are all in action, with Yavi hoping to defend her title.

It won't be easy, as Chemutai returns to the track where she won Olympic gold four years ago, and she will be looking to push Paris 2024 gold medallist Yavi all the way.

All three won their individual heats, setting up an exciting final.
