Will Germany fans still be googling Michael O'Neill's name?

Back at Euro 2012, the Northern Ireland boss paid his own way to attend Germany's 1-0 group win over Portugal in Ukraine.

To get to the match in Lviv, O'Neill boarded a bus full of Germany fans before informing some of his fellow passengers who he was.

"I was only in the job about six months, so when we got on they started to Google me and 'Northern Ireland manager' to see who I was," he explains.

Will Germany's fans recognise their former travelling companion in the Parc des Princes?

Former Northern Ireland youth boss Kenny Shiels, speaking to BBC Radio 5 live: "People outside the dressing room will be saying Northern Ireland have no chance and are the underdogs. We have got seven Premier League players and six Championship players. We're as good as any of them. That's the attitude they have to go in with."

Will Michael O'Neill keep star striker Kyle Lafferty on the bench, along with man-on-fire Will Gregg? Lafferty was an unused substitute for the 2-0 win over Ukraine last Thursday.

Team news from the Parc des Princes coming up in about 25 minutes.

Germany have arrived - a good half an hour after Northern Ireland.

It's not just about Northern Ireland against Germany today, there are two other teams in the group too, you know.

Well, I say two, Ukraine have already been knocked out after losing their first two games without scoring a goal.

Poland will guarantee progression to the knockout stage if they avoid defeat. Even if they lose and Northern Ireland win, four points is likely to be enough to progress to the last 16.

While Northern Ireland's players have been getting used to their surroundings at the Parc des Princes for 25 minutes or so, Germany have yet to arrive.

A helicopter is hovering above the coach carrying the world champions and there's a huge welcome reception waiting for them when they do finally get to the ground.

The permutations are complex, the maths can be confusing - but it's actually quite simple for Northern Ireland.

End the group stage above the dotted line and they are into the last 16.

And a point today would ensure that.

It's the calm before the storm inside the Northern Ireland dressing room as Uefa's TV cameras are allowed in to show lots of green shirts neatly hung up on hangers waiting to be worn.

There's lots of fresh fruit on show. They're going to need that.

Big news coming in from the Sweden camp with striker Zlatan Ibrahimovic announcing he is to retire from international football at the end of Euro 2016. 

"I am very proud of what I have achieved and will always bring the Swedish flag with me," he said.

Sweden face Belgium on Wednesday needing a win to have a realistic chance of qualifying for the last 16.

How are you feeling Northern Ireland fans? Excited? Nervous? 

How big an achievement would it be if Michael O'Neill's side advance to the knockout stage? Would it eclipse the achievement of Billy Bingham's boys at the 1982 World Cup?

If Northern Ireland do advance then hosts France and Wales are both on the radar. Who do you fancy in the next round?

Will Josh Magennis be starting? Team news in around 50 minutes...

Northern Ireland's luxury team coach has a police escort as it swings into the road that leads to the front entrance of the Parc des Princes.

There's a healthy gathering of fans dressed in green shirts waiting to applaud the players as they step off and head straight for the dressing room.

It's a cloudy day in Paris but it's warm enough for T-shirts. Ideal conditions for an upset?

BBC Radio 5 Live

Former Northern Ireland youth boss Kenny Shiels, speaking to BBC Radio 5 live: "I don't think Northern Ireland need any points. I can see three points getting them through. But when you look at how they have done and the capabilities that they have then there is no reason why they can't get a draw against Germany."

Wales have made it. So too England. Will Northern Ireland also qualify for the knockout stages?

This Group C finale presents them with an opportunity to reach the last 16 of their first European Championship in sensational fashion.

A draw will cement a third-placed finish and will be enough to secure their passage as one of the four best third-placed finishers as they would have one more point than Albania and a better goal difference than Slovakia.

One of them are four-time world champions. The other team was as low as 129 in Fifa's world rankings less than four years ago.

One of them features multiple Bundesliga winners and Champions League conquerors. The other a striker who was a postman four years ago as well as a League One defender.

Yet these are exceptional times for Northern Ireland, who step out against mighty Germany in Paris in two hours knowing they can still secure a place in the last 16 of Euro 2016.

Can Michael O'Neill's men write another chapter in their incredible fairy tale?
