Great counter-attacking football from Northern Ireland. It was an excellent save. Well done.

We have our first shot on goal, and it goes Northern Ireland's way. 

It comes from a swift break that ends with Stuart Dallas striking from just inside the area, forcing Wayne Hennessey to push behind.

Good start by Northern Ireland.

Jonny Evans has had clear instructions not to let Gareth Bale out of his sight. Whenever the ball is worked to the Wales forward, Evans is right on him.

The shape is better for Northern Ireland striker Kyle Lafferty. The team look comfortable playing this - it's like a 3-5-2.

Wales are going to try and pass it around at the back and work it up the pitch. They will have the majority of the possession, so it's important that when there's breaks in play Northern Ireland take their time.

Ashley Williams clatters into Jamie Ward midway inside the Welsh half and a free-kick now for Northern Ireland. 

Seven of Northern Ireland's last 10 goals have come from set pieces, but this one is too far out for a shot on goal. Instead, Kyle Lafferty works it out wide then makes a run to the box, but Wales deal with it.

I'm excited, not nervous whatsoever. Northern Ireland have nothing to lose. It's tight in the commentary position here and me and John Hartson are not adverse to throwing an elbow in excitement - so watch yourself.

Wales and Northern Ireland fans have created a terrific atmosphere. May the best team win.

Early bit of pressure on the Northern Ireland defence from that man Gareth Bale. He puts pressure on Gareth McAuley but the defender manages to get the ball back to keeper Michael McGovern.

Moments later, Aaron Ramsey fails to control a ball and it runs out of play. Cue ironic cheers from the NI fans. Early nerves?

I'm nervous. It's going to take a mammoth effort from either side to win. I'm really looking forward to it.

And we are off!

Sully: C'mon #NIR, external the ultimate minnow. The ultimate underdog. The ultimate modest bunch of lads & of course the best chant

Nate Tarrant: This is the one, full of passion desire and drive, looking forward to a great game

Red shirts definitely outnumbering green ones in the Parc des Princes today. Plenty of Wales fans in amongst the NI supporters by the looks of things. We will find out pretty soon who will make the most noise though...

National anthems done, one last hug and a shake of the hands between the players, a huge battle cry from the stadium announcer. Almost time.

Northern Ireland manager Michael O'Neill's biggest decision is whether to press Wales. If they press then Gareth Bale will get space. Bale makes everybody look pedestrian on the pitch. He won't get the sort of room he got against Russia though.

Here we go.

The two teams walk out on to the pitch and huge roar goes up from the stands. Superb atmosphere.

There is a great camaraderie and togetherness among the Northern Ireland players. Their tactics are designed to frustrate the opposition.

With 'Freed from Desire' (also known as 'Will Grigg's on Fire') playing for the Northern Ireland fans and Zombie Nation's 'Kernkraft 400' blaring out for the Welsh, the noisy Parc des Princes has the peculiar feel of an enormous nostalgia nightclub. 

It beats Flares, I suppose.

Daniel Woodley: Good luck to both #NIR, external and #WAL, external! Both done incredibly well to get this far. The support for both will be something to behold! 

Jon Fowell: Nearly game time.... Will Griggs on fire!!   

The Clowez: I am torn between who I'd like to progress between #WAL, external & #NIR, external but good luck, and may the best team win.
