Pre-match tonight, Hampden will fall silent to remember those who died in the explosion in Creeslough in County Donegal.

Players in both teams will also wear black armbands as a tribute.

Caroline Weir again takes her place in Scotland's midfield. The skilful 27-year-old is a joy to watch, but she's only been on the scoresheet once in this campaign - away to the Faroe Islands.

Will we see some magic tonight? To get you in the mood, here's a piece about Weir's rise from Dunfermline to Real Madrid.

Hampden under the lights is a beautiful sight for the eyes.

Bit of warming-up for final preparations before kick-off.

My warming up you ask? I'm away to dig out the gloves from the depths of my bag.... and grab a quick cuppa too.

Scrap that, it's been disallowed by VAR for offside following a lengthy check. As you were...

Switzerland have just taken a late lead at home to Wales. With five minutes to go, Scotland or the Republic could be doing with a Welsh goal...

It's about blocking out what is going on outside of the game. We have started to get more and more media attention, and more and more questions are being asked. They have handled it so well throughout qualifying. Speaking to the girls, I think that is what has happened. They have concentrated on getting ready for the game. That's all they can do.

You're a brave soul if you're gonna try and predict what the permutations are for booking plane tickets to Australia and New Zealand... and for what month that flight is departing.

Keep it simple, let's look after ourselves, win and score some goals.

Football is a simple game, eh?

It's currently Switzerland 1-1 Wales as Iceland have just levelled in Portugal.

While simplifying this a bit, the teams at Hampden tonight could be doing with Switzerland OR Iceland losing.

Hopefully one of them slips up before extra time confuses things further.

Vera Pauw's team cruised to second place in Group A, racking up 17 points to finish seven ahead of Finland and five points behind Sweden. Their only defeat came against the Swedes last October in a 1-0 reverse.

If they win tonight, it'll be the first time Republic of Ireland will have made it to a Women's World Cup. Exciting!

While the Irish got a pass straight into tonight's play-off final, Scotland were made to work for it last Thursday against Austria.

A dreich night in Glasgow looked an ominous sign as the semi-final lingered into extra time. That was until Abi Harrison's crashing header won the day for the Scots, who finished second in Group B.

Just the one change from the side that took to the sodden Hampden turf on Thursday evening.

Lana Clelland cut a dejected figure as she hobbled off at half-time but was replaced by a revitalised and ready Fiona Brown.

Some effort from her to continue battling back from serious injury.

Scotland: Gibson, Evans, Corsie, Howard, Docherty, Kerr, Weir, Cuthbert, Brown, Emslie, Thomas.

Substitutes: Fife, Cumings, Mitchell, Beattie, Clark, Graham, McLauchlan, Hanson, C Murray, Harrison, Clelland, Grimshaw.

Republic of Ireland: Brosnan, Finn, Fahey, Quinn, Caldwell, Campbell, D O'Sullivan, Agg, O'Gorman, McCabe, Payne.

Substitutes: Moloney, Walsh, Scott, Mustaki, Carusa, Barrett, Quinn, O'Riordan, Nolan, Noonan, Grant, Farrelly.

Right, back to Glasgow. The lights are on, the fans are trickling in, and the teams are out. Here they come...

Anyone else confused?

To say my brain is fried trying to work this out over the last few days is a bit of an understatement.

To keep it simple, of the three play-off winners tonight, the two sides with the best qualification record - including tonight's result but not the semi-finals - will go to the World Cup next year. The team in third head to another play-off game next February.

As things stand, both the Republic of Ireland and Scotland need other results to go their way to make it into the top two for whichever nation triumphs.

Both those games are both level at half-time, so everything is still a bit up in the air. We'll keep you posted with developments.

Good evening and welcome to what could be a huge night for either Scotland or Republic of Ireland at Hampden.

Victory in this play-off final could - more on that in a minute... - bring qualification for next year's Women's World Cup.

Whether you've been following the campaign for your team or are just joining us, stick around to watch, read and listen to all the action unfold from Glasgow. Drama is surely guaranteed.
