Wales need to go for it now and Jess Fishlock puts in a fine cross to the back post, where Rachel Rowe is just beaten to the ball.

Corner to Wales.

A second change for Norway.

Striker Elise Thorsnes is replaced by Lisa-Marie Utland.

Wales fans can just click that 'thumbs down' button now.

Northern Ireland have beaten Belarus 1-0.

If the results stay the same as they are now, Wales' qualification hopes are almost definitely out of their own hands.

Wales midfielder Angharad James is booked for a late challenge on Norway goalkeeper Cecilie Fiskerstrand.

I would think Wales might change their formation to give their attacking players more licence to go forward.

They can't be so deep now. They have to have people further forward.

A first change for Norway as Amalie Eikeland comes on for Guro Reiten.

Decent chance for Norway right-back Ingrid Wold.

Rachel Rowe heads clear a cross from Julie Blakstad and it falls kindly for Wold.

But the Everton player fires a wild first-time effort wide and over.

Norwegian keeper Cecilie Fiskerstrand has spent most of this game very high up the field.

With her team almost exclusively in possession and in the opposition half, that's fair enough.

Wales' players think there's a chance of catching Fiskerstrand off her line so a few of them have tried shooting from the halfway line.

None of those efforts have come close yet but it might be worth pursuing if they can really connect with one.

Wales captain Sophie Ingle is having a big game at the heart of her team's defence, heading and clearing everything that comes her way.

The Chelsea player is an excellent passer of the ball too but she hasn't been given the opportunity to demonstrate her range today with Wales under so much pressure.

Norway carry on where they left off in the first half, bossing possession and territory.

Karina Saevik wriggles her way into the Welsh penalty area and has a low shot blocked by Laura O'Sullivan.

Wales get the second half started - twice.

Sophie Ingle tries a shot first time, then the referee orders a retake and the Wales captain boots the ball into touch deep in the Norwegian half.

Norway have had lots of the ball but except for the early Thorsnes header they haven't had clear-cut chances, just long-range efforts and crosses.

I think Jayne Ludlow will be pleased with the first half, it's a question of whether they can maintain that for another 45 minutes.

With 1.4 million women and girls playing football, there's no doubt that it's the nation's most popular female-team participation sport.

Around the UK there are schemes designed to help girls get into football - from grassroots to the professional game - as well as routes into coaching.

Each Football Association across the country has information specifically to encourage women to play so get contacting in Scotland, external, Wales, external, Northern Ireland, external and England., external

Wales are halfway towards a seismic result.

It appears being defensively resolute and organised.... makes you very hard to breach.

A point will be massive for Wales.

Gwennan Harries
Former Wales striker

Wales wanted to frustrate Norway and they've done that well in the first half.

Wales will be delighted with that scoreline.

Jayne Ludlow's side set out to frustrate their opponents and they've done just that so far.
