Matthew: Absolutely mad what Luke is doing, he definitely brought me to the sport, what an icon!

Luke: Luke may miss and Luke may hit, no matter who wins what a great night to be a Luke.

Andy and Jamie: If Littler wins today, to honour the occasion, we’re giving all our employees a new dartboard.

Luke Humphries has hit a treble on every visit to the board. Oftentimes two or three of them.

He's on fire and threatening another break.

Luke Littler almost rescues the leg, just misses a bullseye finish - and Humphries takes out double two for a fifth leg on the spin.

It's the manner Littler played in that set - he didn't play well and he's already astray early in this set too.

The world number one is on the front foot.

Tournament sponsors Paddy Power have pledged to donate £1,000 to Prostate Cancer UK for every 180 scored during the World Championship - and there have been a whopping 878 so far.

The tournament record of 901 is almost certain to be broken - and tonight's two combatants have already forced the bookmakers to hand over £100,000 to charity just on their own.

Both Littler and Humphries have amassed 50 maximums in the tournament so far - and, as well as the world title, they are battling it out for the Ballon d’Art trophy, a specially commissioned golden gong to be handed to the player scores the most 180s and ultimately raises the most money for charity.

For Humphries, the trophy would be extra special as his girlfriend’s father is currently undergoing treatment for prostate cancer.

"It would be very, very special to me and I really want to give it to my father-in-law who has gone through the process of getting checked out and finding out that he has got it," he said.

“It was early stage so it can be managed and monitored. He caught it early and that’s testament to the fact that checking your risk does matter. He did and it might have saved his life."

Abdul: Am watching darts for the first time in my life and don't even understand the scoring system of the game. However, ever since I heard about Luke Littler on the news, I've just been fascinated by how mature and composed he is. Good luck to him, and whatever happens, he has brought my attention to this sport.

Good to have you with us, Abdul - I'll do my best to explain things as we go along!

Massively impressive first set from the world number one.

Luke Littler lands a 180 late in the fourth leg - but Humphries was already on a double and he takes out 16 to bag the opening set.

Couple of trebleless visits for Luke Littler could well let Luke Humphries in here.

Yep, Humphries misses a couple of darts at a double but nails double five. Early break.

Rapid-fire reply from Luke Humphries, aided by the first 180 of the night, as he levels matters.

They don't mess about these boys, almost speed darts this.

Drama from the get-go as Luke Humphries misses a dart for a break of throw at double top.

And Luke Littler nails the same target with his first effort at it.

Tim: The danger for Luke Littler tonight might be the thought, if he wins, where do you go from here?

Craig: What a remarkable few days for this young fella. Let's hope his feet remain firmly on the ground - though I think it will be difficult!

Luke Littler won the bullseye battle in the practice room - and the 16-year-old opts to throw first.

But he opens with just 41. Brushes that off with a 140 next.

Luke Littler beat Rob Cross 6-2 but the game was closer than that; he missed a lot of doubles. With Luke Humphries, I don’t think he’ll get away with that, so he’s got to be on the ball in his game tonight.

Humphries had a 106 average over all those six sets – that’s a lot. Luke Littler had a 103 average, which all right, is not that much less, but it makes a difference over a long game.

Littler's got a chance to win it, but I just think Humphries might do it because he’s got a lot of experience. He’s won three major tournaments already and this would be the icing on the cake for him.

The new world number one Luke Humphries is more of a kisser with his nearest and dearest as he makes his way to the oche.

Will he be kissing the Sid Waddell Trophy in two hours' time?

It's nearly time.

Luke Littler is first out.

Hugs and fist-bumps aplenty for friends and family. He looks as cool as a cucumber.

Luke Littler's story has certainly captured the nation's attention and we're expecting droves of darts fans to be following our live text coverage of tonight's final.

Please get in touch with your thoughts as the match progresses and we'll publish as many as we can.

We'd love to hear from fans in attendance at Ally Pally tonight too. It's the hot ticket in town apparently.

Ticket trading website Viagogo has reported a "surge in demand" for final seats, with the average price rising to £238 per ticket, £73 higher than for last year's showpiece.

Warrington Wolves rugby league stars Josh Thewlis and Matty Ashton - as well as the club's mascot Wolfie - were present at Ally Pally to cheer the 16-year-old through his semi-final win.

The duo presented Littler with a Wolves shirt emblazoned with Littler 180 on the back.

Thewlis said: "It must be pretty daunting for a 16-year-old to be up there on the big stage on his own.

"When I was 16 I was still turning up to training feeling star-struck by everyone, but I had 12 other blokes with me on the field who I knew would be able to help me out.

"Somehow Luke seems to be taking it all in his stride."

• Littler’s three-dart tournament average is 101.82, he has thrown 50 180s and crucially is operating at a 45 per cent success rate on checkouts.
• Humphries’ average is slightly down at 99.33, but he has also thrown a half-century of maximums and has taken out 41 per cent of his double attempts.
• Humphries is the form player in the world and extended his winning run to 18 when he beat Scott Williams to reach the final.
• It was October 29 when ‘Cool Hand’ last lost, falling to James Wade in the European Championship. He won the Players Championship a week later, which was his third major title in six weeks.
• Littler, meanwhile, is unbeaten in 21 matches going back to August in PDC events, which included him winning the World Youth Championship.

But despite his growing admiration for Luke Littler, referee Russ Bray feels world number one Luke Humphries could be the man to end the teenager's magical run.

"Humphries has won the last three PDC TV tournaments and he's only 29, we lose the perspective of age here," said referee Bray.

"Littler is a kid but Humphries is only 29 years of age. He's very much a young man in the sport. His talent is also amazing.

"He's gone to world number one now by getting to the final and I honestly think he could be a party spoiler."

Should Luke Littler triumph tonight, he will become the youngest world champion by quite some margin. Michael van Gerwen was 24 years and nine months when he won his first title to set the record in 2014.

Darts referee Russ Bray, for whom the final represents his last World Championship match, believes three-time world champion Van Gerwen is the only player comparable to Luke Littler at his age.

"At 17, Michael was unbelievable, the same as Luke, hitting nine darters in TV tournaments," Bray told BBC Radio 5 Live.

"For Luke to come through the way he has done is incredible. He's taken out some really big names and he seems so, so cool.

"He's certainly an entertainer, which is what you want. You want style in the game. He's a raw talent and when you see how he performs up there, with no fear at his age, it's a breath of fresh air."
