Switzerland versus Poland has gone to extra time thanks to that Xherdan Shaqiri wonder goal, which you can watch by clicking on the above video.

It's been hailed by many on social media as the goal of the tournament.

My colleague sat next to me described it as 'nothing special'. 

I'm considering moving seats.

Watch the rest of Switzerland versus Poland here.

Northern Ireland boss Michael O'Neill says his players are desperate to prolong their Euro 2016 adventure by beating Wales.

"We don't want this to end. The players want more," O'Neill said. 

"The prize is massive for both teams. We are playing for a place in the quarter-finals and we have to make sure it is us going through."

It's OK for some. My balcony overlooks a supermarket car park...

Wales have the player: Gareth Bale, I don’t believe he feels any pressure. He plays for Real Madrid and won the Champions League, they go into the game as red-hot favourites.

We know Gareth Bale - joint top scorer at Euro 2016 with three goals - is capable of scoring the spectacular too. 

The Real Madrid forward scored in each of Wales' three group games, becoming the only player to do so since Milan Baros of the Czech Republic and Netherlands’ Ruud van Nistelrooy at Euro 2004.

However, Northern Ireland have proven they have the defence to frustrate some of Europe's top talent. They conceded just two goals in a group that contained world champions Germany as well as Poland and Ukraine.

We could be in for a very tight contest.

Wales go in to the game not being underdogs for once. 

Northern Ireland have their set-pieces and they have nothing to lose. It will be interesting to see how Wales deal with the pressure.

Note the double brew action on the bottom right. A not too dissimilar sight to BBC Sport HQ in Salford.

This is Wales’ first visit to Paris, so they might have to look beyond football for a little inspiration.

Their rugby counterparts have certainly enjoyed success in this city, the most notable perhaps being their 1975 triumph at Parc de Princes which set them on their way to a Grand Slam.

The fixture is a part of Welsh rugby folklore thanks to prop Graham Price’s remarkable try on debut, belying his status as a burly front-rower to run the length of the field for a memorable score which prompted commentator Nigel Starmer-Smith to say: “They’ll never believe it in Pontypool!”

This is the venue for today's game - Parc des Princes in Paris. It's Wales' first trip to the stadium in this tournament, but Northern Ireland were here just a couple of days ago when they were beaten 1-0 by Germany in their final group game.

Northern Ireland fans are milling around the restaurants and bars close to the Parc des Princes before the big game. 

There was a mad scramble to get tickets and arrange flights for the last 16 match - now it is time to see if Michael O'Neill's men can get to the quarter-finals. What an achievement that would be for Northern Ireland. 

Having squeezed through as one of the third-placed finishers in the group stages, NI are underdogs against a Welsh side which topped their group. 

Gareth Bale, Aaron Ramsey and Joe Allen have the star quality which Northern Ireland perhaps don’t possess. But O'Neill's men are well organised, have a great team spirit and loads of heart - qualities which have got them this far. 

A quarter-final in Lille on 1 July is the prize today's winners will grasp. 

"It is up to us to make sure it is us. The players are fully aware of the significance of this match," said the NI manager.

Box off the next few hours because it is all about the football. You can watch the Switzerland/Poland game right now on BBC One and online here, and also listen to commentary via BBC Radio 5 live.

It will be the same deal for Wales versus Northern Ireland later, with BBC One build up to that game starting at 16:10 BST.

There have been four World Cup or European Championship qualifiers, countless British Home Championship games and the odd friendly - but this is Wales and Northern Ireland's first meeting at a major finals.

Wales go into the match with the historical advantage, having won 15 of their 34 previous meetings since 1953.

Both sides will be well aware that the past form counts for nothing because the high pressure and intensity of a knockout tie means anything can happen...
