Nicolai Budkov Kjaer and Viktor Durasovic fight their way back from 0-30 down to bring up game point, but Lloyd Glasspool forces deuce by plucking the ball out of the air and smashing it past Budkov Kjaer.

Lloyd Glasspool is having a good serving day.

He and Cash have won all 12 points on his serve now.

Another very routine hold to love for the Brits.

Are they in Oslo or Greece?

The British fans are jumping along to some Greek-inspired music and it looks like a real party atmosphere inside Nadderud Arena.

GB are just one set away from wrapping up this Davis Cup tie.

Nicolai Budkov Kjaer sends the ball into the net and that will be that for the first set as Julian Cash and Lloyd Glasspool break for the second time.

The British pair haven't gave Budkov Kjaer and Viktor Durasovic a sniff yet.

A superb return down the line from Julian Cash brings up set point number three.

Third time lucky?

Nicolai Budkov Kjaer saves the first break point, Lloyd Glasspool whacks the second one out of play.

Deuce.

Julian Cash can't do much with that body serve, but he's ready and waiting at the net for the next point. All he has to do is hold up his racquet and dink the ball over. Set points for the British duo.

Viktor Durasovic and Nicolai Budkov Kjaer can only stand and look at each other as Julian Cash thumps a smash volley down the T, well out of their reach.

The British pair have been clinical with those types of shots and it's another comfortable hold.

The Norwegians have won just one point on the Brits' serve.

Nicolai Budkov Kjaer smashes down a volley which a scrambling Lloyd Glasspool can't get to, and the Briton is unlucky with the next point as the ball clips the net cord and trickles back onto their side of the court.

Another game on the board for Norway.

Lovely stuff from Nicolai Budkov Kjaer, who starts the game with an ace before bringing up game point with a delightful backhand volley.

But Great Britain claw their way back, with Lloyd Glasspool sending a return straight into Viktor Durasovic before Budkov Kjaer goes long.

And again! Deuce.

Julian Cash and Lloyd Glasspool set themselves up nicely for the rest of the game with some brilliant net play in the first point before Nicolai Budkov Kjaer goes wide on the next one.

A smash and grab by Cash at the net, and then an unreturnable serve by Glasspool see the British pair through.

That's two holds to love on Glasspool's serve.

Sealed with an ace! A much better service game from the Norway duo, with Viktor Durasovic catching out Julian Cash a couple of times with some big serving.

The home side are on the board.

A winner from Nicolai Budkov Kjaer down the tramlines gives Norway a half-chance at 15-30, but the British pair work their way back into the game and an overcooked forehand from Budkov Kjaer secures the hold for Julian Cash and Lloyd Glasspool.

They get it! The British pair both find themselves at the net, but Nicolai Budkov Kjaer's attempt to go over them both lands beyond the baseline.

A strong start for GB.

Viktor Durasovic took a tumble there and that left Julian Cash with enough space to squeeze a speedy forehand between the two Norwegians to pull level at 30-30.

Nicolai Budkov Kjaer plants a forehand into the net, so the British duo will have an early chance to break.

A solid service game from Lloyd Glasspool to get Great Britain back up and running in Oslo.

Away we go. Britain's Lloyd Glasspool is serving first to get us under way...

Viktor Durasovic skews a shot wide before Glasspool lands a service winner down the line. 30-0.

*denotes next server.

Norway have opted to use their two singles players for the doubles, with Viktor Durasovic and Nicolai Budkov Kjaer back in action.

Durasovic is ranked 491st in doubles, while Budkov Kjaer sits outside the world's top 1,000.

So a win for the Norwegian pair against Julian Cash and Lloyd Glasspool would be a big, big upset.

Great Britain's Julian Cash and Lloyd Glasspool will be the overwhelming favourites for today's double match.

They won Wimbledon together last summer - becoming the first all-British pair to win the men's doubles title at the All England Club for 89 years.

And four months later, they became the first all-British pair to secure the year-end world number one men's doubles ranking.
