It’s not quite as warm here as it was in Nice for Northern Ireland’s first match against Poland.

That will be welcome for Michael O’Neill’s men, some of whom admitted to being absolutely exhausted after Sunday’s Group C game.

How Northern Ireland start will be important, because they struggled to get hold of the ball in the early stages against the Poles.

They need to get to grips with this one from the start, and they know it.

I've seen a few of those shirts in Doncaster's Ukrainian Social Club...

Northern Ireland know they must not lose today. Otherwise they will be checking in at Charles De Gaulle airport after Tuesday's final game against Germany in Paris.

"Seven teams lost their opening game so it is not as if we have been cut adrift from the tournament," says boss Michael O'Neill.

"We need to stifle our opponents and exploit their weaknesses. We did the first part of that well against Poland."

The Northern Ireland lads are already in the Lyon tunnel. They're ready to crack on. The Ukraine boys stroll in a few moments later. Some granite jawlines in that lot. Here we go then...

Ten minutes until kick-off. Time for you to quickly boil the kettle and grab a pack of custard creams. While digesting the two line-ups...

Those lucky Northern Irish fans over in France will, I'm sure, have been learning a few stock phrases ahead of their trip. You know, like... 'Ou est la gare?' Or 'je voudrais trois bieres s'il vous plait'. The important stuff.

But a group of Northern Irish school children have been learning a few other bits of football-specific lingo.

'Catch yourself on ref', 'get wired into them', 'let's all do the bouncy!' and many more. Learn the lingo here.

Indie classic turned football anthem, Seven Nation Army, is blasting out in Lyon as the stands fill up ahead of kick-off. Plenty of colour from both nations as you would expect. My favourite outfit has been the one worn by this guy...

Bet he was 'air-guitaring' to Jack White's solo...

Jonny Evans knows a thing or two about cup finals having played in plenty over the years for former club Manchester United.

"We've got to treat it like a cup final," says the West Brom defender.

"We have to stamp our authority on the game and put in a better performance. 

"We didn't play really badly but at certain times we would have liked to create more chances."

Last week Northern Ireland's players watched a motivational video from Rory McIlroy.

This week they have got Jim McDonald. Charlie Lawson, who plays the Coronation Street hard man, sent his own personal (and slightly scary) message. Catch yourself on.

Plenty of Norn Iron fans are already inside the Stade de Lyon. The stand behind one of the goals looks greener than the pitch in front of them. 'Sweet Caroline' - that Neil Diamond classic adopted by the Green and White Army - is being blasted out over the PA system.

Striker Kyle Lafferty will be disappointed. Having played a lone striker role – with little support – against Poland, he has been left out of the team.

Ukraine are a big team, and maybe Conor Washington and Jamie Ward are the men to get under their skin.

What a story for 36-year-old defender Aaron Hughes, the man who came out of retirement for Michael O’Neill few years ago.

The former Newcastle, Aston Villa and Fulham man doesn’t have a club right now – having most recently played in Melbourne – but here he is playing in Euro 2016.

He reached his 100th NI cap as a sub in the final warm-up game against Slovenia, but wasn’t expected to play in France.

Manager O’Neill is clearly banking on experience in a back four which contains another whose 36th birthday is behind him, West Brom’s Gareth McAuley.

Ukraine, who have also qualified* for their first finals, make a slight tweak to the team which started Sunday's 1-0 defeat by Germany.

Shakhtar striker Yevhen Seleznyov starts ahead of Dnipro's Roman Zozulya.

Ukraine XI: Pyatov, Fedetskiy, Khacheridi, Rakitskiy, Shevchuk, Sydorchuk, Stepanenko, Yarmolenko, Kovalenko, Konoplyanka, Seleznyov.

* Yes, they played in the 2012 finals. No, they didn't qualify because they were co-hosts.
