So really dodgy doubling here, from both men in truth, but it costs Michael van Gerwen as he misses five at the outer ring to level the match.

You just can;t do that against Luke Littler, who hits double five to go back into a two-leg lead after a huge let-off.

Luke Littler misses tops and double 10 to see-off 56, leaving Michael van Gerwen with a must make on 57.

He misses tops but he manages to hit the cover on double 10 to stay alive with a break of throw.

About the only blemish for Luke Littler so far is the miss on double 10 - a rarity for him - in this fourth leg.

Luckily, he still has a dart in hand and he's not missing two of them. That's a break of throw for a two-leg lead.

Luke Littler goes off favourite to win every Thursday.

I think he's favourite to be Christmas number one, and second favourite in the Boat Race.

Michael van Gerwen wasn't level for long, as Luke Littler sticks in an effortless 11-darter to restore his lead.

The teenager makes the game just look so easy at times - and it's really not!

A second 180 of the match for Luke Littler piles on the pressure, but Michael van Gerwen answers it by taking out 110 to level the match.

The way Littler's started this match MVG will need a few more big finishes like that to stay in touch.

Michael van Gerwen hasn't reached a Premier League final since week 15 in May of last year.

A 180 for Luke Littler leaves 81 and with Michael van Gerwen miles behind he can just set it up to return and win the leg in 13 darts.

Here we go then. Luke Littler has the throw in the opening leg, but who wins?

Thumbs up for Littler, down for Michael van Gerwen.

Right, on to the semi-finals where first up we'll get a rematch of the World Championship final at Alexandra Palace as Luke Littler faces Michael van Gerwen.

Littler has won five of the last six meetings, including that world final, but this season in the Premier League the score is 1-1.

There it is - still no points for Stephen Bunting in the Premier League with a fifth straight defeat coming courtesy of an inspired Nathan Aspinall.

You have to feel for Bunting, who may have fancied bagging his first win here, only for Aspinall to produce some of his very best ever arrows.

A 106.46 average for Aspinall with six 180s and a 140 checkout as part of his 60% doubles percentage from hitting six out of 100 attempts.

Bunting is in trouble yet again.

Stephen Bunting isn't throwing the towel in here as he takes out 80 to win a leg against the darts.

A coupel of sloppy visits cost Nathan Aspinall as maybe he just started to think about playing Rob Cross in the semi-final.

Nathan Aspinall is storming towards the semi-finals and he's producing arguably his best match of his Premier League career.

He's just one away now from victory.

Nathan Aspinall was scratching for form last week and looked really uncomfortable with his game - he's looked the exact opposite this week as he takes out 69 to lead by three.

He's averaging almost 108 so far in this match and has hit four doubles from just seven attempts. Stephen Bunting will need some comeback here if he's to win his first match of the Premier League season.

Back-to-back 180s leaves Nathan Aspinall with the chance of another 11-darter - and although he can't quite manage that, Stephen Bunting fluffs his lines allowing Aspinall to return and complete the break of throw.

It's not a perfect leg but Nathan Aspinall does at least win it - under a little bit of pressure as well which, when he's just won it on his own throw in 11 darts, tells you that Stephen Bunting is also playing pretty well.

Nathan Aspinall is on a nine-darter! Backto-back 180s is followed by a seventh treble 20, but he misses the treble 19 with the crowd all on their feet desperate to see another perfect leg of darts.

Stephen Bunting leaves 40 and altough he misses his first effort, and his first at double 10 he nails it second time around.

Stephen Bunting is sat on 108 hoping to get a shot at a break, but Nathan Aspinall pops up to take out 140 to hold his throw in 15 darts.

A high-quality start from both men in our last quarter-final.
