Gwennan Harries
Former Wales striker on BBC Two Wales
How much running has Jess Fishlock done?
She made her debut against Switzerland and scored a great goal on her debut.
It was the only time Wales beat Switzerland.
Switzerland 1-1 Wales
A quick break from the hosts, but Rachel Rinast's cross is poor and Laura O'Sullivan gathers.
Switzerland 1-1 Wales
A lot of players going down and needing treatment.
Wales' players have given so, so much in these past two games.
Rachel Rowe the latest to require treatment.
Switzerland 1-1 Wales
What a run from Ramona Bachmann!
She weaved through like Diego Maradona, but her shot was tame and Laura O'Sullivan saved.
Switzerland 1-1 Wales
Laura O'Sullivan spills a corner, but Wales get away with it.
Switzerland 1-1 Wales
Katie Sherwood
Former Wales midfielder on BBC Two Wales
I think what we are doing is trying to hit them on the counter.
With the pace of Ffion Morgan now coming on that's something we look to do.
We have to brave in defence and in possession and look after the ball as that's the only way we are going to get goal.
Switzerland 1-1 Wales
Portugal have taken the lead just two minutes into their extra time against Iceland.
They now lead 2-1 thanks to Diana Silva's goal.
Switzerland 1-1 Wales
Jo Price
Former Wales goalkeeper on BBC Radio Wales
I feel like I've played ninety minutes myself!
Full credit to the girls for holding out this long.
Wales haven't had a lot of possession for the second half so could we snatch it? I'm hopeful.
Switzerland 1-1 Wales
We are under way again.
Extra time in the World Cup play-off final.
Pressure.
Switzerland 1-1 Wales
That's it.
To extra time we go.
That second half had it all.
A missed penalty, two disallowed goals.
Somehow, someway, Wales are still in this.
Let's do 30 more minutes.
Switzerland 1-1 Wales
Kath Morgan
Former Wales defender on BBC Cymrufyw
Switzerland have had control in this second half and have created so many problems throughout for Wales.
Switzerland 1-1 Wales
Extra time awaits in Portugal where Portugal and Iceland have drawn 1-1.

Gareth Bailey
BBC Sport Wales at the Stadion Letzigrund
Jess Fishlock has absolutely run her socks off this campaign for Wales.
You feel like if anyone is going to will Wales over the line, it's going to be a moment of quality from her.
We had one in extra time against Bosnia-Herzegovina on Thursday, has she got any more magic in her locker here?
Switzerland 1-1 Wales
Wales clinging on.
They have had two massive reprieves tonight, with a missed penalty and a disallowed goal.
Tired as they are, they will definitely take extra time.
Switzerland 1-1 Wales
Rachel Rinast heads just over.
Switzerland 1-1 Wales
Gwennan Harries
Former Wales striker on BBC Two Wales
I'm really pleased to see Lily Woodham come on, she's really explosive and dynamic.
Switzerland 1-1 Wales
Gareth Bailey
BBC Sport Wales at the Stadion Letzigrund
In the last game against Bosnia-Herzegovina, Wales had four goals ruled out for offside.
VAR feels a bit sweeter tonight if you are a Wales fan.
It was only used for the first time in a Wales women's international last time out - you have to think they'll be happier with the usage tonight.
Switzerland 1-1 Wales
We will have EIGHT added minutes.
And then maybe 30 more.
Switzerland 1-1 Wales
Gwennan Harries
Former Wales striker on BBC Two Wales
I think if a doctor was here and measuring my blood pressure he wouldn't be very happy!
Switzerland 1-1 Wales
That was a really, really tight offside call.
In the group, that would have counted.
Anyway, a Wales change.
Kayleigh Green is off, she's worked so hard.
Lily Woodham replaces her. More pace.
Svenja Fölmli is replaced by Rachel Rinast for the hosts.
