A wall of red and a sea of green are the sight that meets you as you arrive at Parc des Princes, which is filling up very quickly. The pitch is bathed in warm Paris sunshine and both sets of players are warming up. Northern Ireland goalkeeper Michael McGovern is having shots rapidly fired at him in a style reminiscent of his last appearance here, against Germany a few days ago.

We have our first quarter-finalist as Poland beat beat Switzerland 5-4 on penalties after a 1-1 draw.

That means Gary Lineker and company are cracking on with build up to Wales versus Northern Ireland right now on BBC One, and at the top of this page.

A final reminder of the Northern Ireland team before kick off. One change, with Kyle Lafferty in for Conor Washington.

Northern Ireland XI: McGovern, McAuley, J.Evans, Davis, Lafferty, C.Evans, Dallas, Norwood, Hughes, Ward, Cathcart

Aaron Hughes is the man tasked with keeping Gareth Bale quiet today.

The former Newcastle, Aston Villa and Fulham defender is currently without a club. If he manages to tuck Bale into his back pocket today, he could well find his phone ringing with a few offers tonight...

And as if on cue, the Parc des Princes DJ has just whacked on Freed From Desire. That's got everyone going in the stands.

Everyone knows about Will Grigg's on fire, right? I'm fairly certain lost tribes of the Amazon have heard the song. 

I was almost starting to get tired of it. Almost. Then I watched a bare chested Eric Cantona sing it., external

The age of social media. What a time to be alive.

Wales really found their mojo in their win against Russia so it is going to be difficult for Northern Ireland - but winning this tie is nowhere near insurmountable.

We will just have to be extremely disciplined defensively to stifle them

With two of the loudest sets of fans at Euro 2016 in Paris today, Parc des Princes will be bouncing when Wales take on Northern Ireland.

It will be in stark contrast to the last time the two sides met at a neutral venue, when they were watched by just 529 spectators at the Aviva Stadium in Dublin in the Nations Cup in 2011.

Wales won 2-0 on that occasion but the most recent encounter, a friendly at a close-to-capacity Cardiff City Stadium in March, ended in a 1-1 draw.

There will be almost twice as many people at the Parc des Princes this evening, so a pair of earplugs might come in handy.

More than 30,000 Wales fans are expected to be in Paris to cheer their side on today, and Gareth Bale reckons his home nation's supporters have played a massive part in their progress to the last 16.

"The support from our fans is incredible," said Bale. "We call it the Red Wall. You know like Borussia Dortmund you see the Yellow Wall, we call it the Red Wall."

Wales and Northern Ireland fans are mingling as kick off approaches, enjoying some good natured banter. Always good to see.

Hang on, is that a camera strapped to the Northern Ireland fan's wig?
