Poland 1-0 Northern Ireland
Poland midfielder Bartosz Kapustka, the nippy 19-year-old, comes rushing into the box again but he's expertly tackled by Conor McLaughlin.
Kapustka, who play his club football for Cracovia, has really been impressive tonight.
Poland 1-0 Northern Ireland
Arkadiusz Milik is causing trouble in the box, but a different kind of trouble.
The Poland forward, in the Northern Ireland box, brings down Oliver Norwood and NI earn a free-kick. The green and white army boo furiously at that one.

Oliver Cook: A goal down. I think it's time for Northern Ireland to bring on a certain fella who's on fire..
Matias del Azar: Nor Ire have not played any real football, you would understand if it was Germany but it's Poland. Need to be more ambitious.
Tim Collingwood: It's been coming. Gutted for NI. Milik is such a dangerous player.
Poland 1-0 Northern Ireland
Gareth McAuley takes his time with the set-piece.

Gerry Armstrong
Former Northern Ireland striker
"It's an excellent strike which goes through the legs of Craig Cathcart. Northern Ireland will now have to be a lot more adventurous."
Poland 1-0 Northern Ireland
Gerry Taggart
Former Northern Ireland captain in Nice
"It was a quality ball into Milik's feet and once he got it onto his left foot there was only going to be one outcome.
"Not winning the second ball was vital.
"There is plenty of time for Northern Ireland to get back into the game but they have to start now getting on to the ball."
Arkadiusz Milik
We have a breakthrough in Nice!
Jakub Blaszczykowski swipes the ball across the box and it finds Arkadiusz Milik, who controls on his left foot and fires through the legs of Craig Cathcart into the back of the net.
Northern Ireland have to come out and play now.
Poland 0-0 Northern Ireland
Gerry Taggart
Former Northern Ireland captain in Nice
"I think we had to do something. Although we defended well, the pressure was mounting and Northern Ireland were looking a little bit cagey towards the end.
"I think Northern Ireland have reverted to a system that suits them better."
Poland 0-0 Northern Ireland
Michal Pazdan is forced to clear for Poland after a decent run from Stuart Dallas up the right hand flank.
Leeds United midfielder Dallas is looking lively already after coming on five minutes ago.
But Poland regain possession and Kamil Glik feeds the ball in from distance, in a bid to find Robert Lewandowski, but the keeper gathers.
Poland 0-0 Northern Ireland
Northern Ireland still haven't had a shot on goal and our friends at Opta tell us the last team that did not attempt a single shot (including blocked) in a first half at the Euros was Italy versus the Netherlands in 2000.
Poland 0-0 Northern Ireland
Injured Northern Ireland midfielder Chris Brunt: "It’s been OK - both teams are looking to not lose the game. We have defended pretty well but other than that one good save from Michael McGovern he hasn’t had too much to do. It's been a bit disappointing how we have dealt with the ball when we have it. In qualifying, we have been used to having less possession than the other team so as it goes on, it might suit us.
"You can see the lads all working hard for each other, they'd run through brick walls for each other, and they have plenty to talk about in the dressing room. We are only a set-piece goal from taking the lead. We just need to hold onto the ball a bit better."
Poland 0-0 Northern Ireland
We're back under way!
Stuart Dallas has come on for Paddy McNair for Northern Ireland. That's the only change at half-time.
Poland 0-0 Northern Ireland
Neil Lennon
Ex-Northern Ireland international
"The next 10-15 minutes are so important. Can Poland pick up the pace of the game again? Can Northern Ireland keep their shape?
"The worry when you are always defending is if Poland go ahead, are they going to get two or three?"
Poland 0-0 Northern Ireland
Decent, this, from Bartosz Kapustka, who has been good for Poland.
I've been informed by my Polish friend that a literal translation of his name is "little cabbage".
This makes me like him even more.

Peter McMillan: Well done NIR in shutting out POL during first half at EURO 2016 - but it won't get any easier as the game goes on.
Andrew Bryce: Feels like an FA Cup tie. Backs against the wall, but we've kept them out so far!
Jasdip Sagu: Can Northern Ireland be the Greece of Euro 2004? The Irish are defending resolutely!
In case you missed it earlier, Uefa has threatened to disqualify England and Russia from Euro 2016 if there is any further violence by fans.
And, according to the Times’ chief football writer Henry Winter, the Football Association “doesn’t have a clue how serious” Uefa’s threat to expel England from Euro 2016 is,
“It is a huge threat” said Winter, speaking to Gabby Logan on Facebook., external
"Unfortunately the English have previous. In 2000 in Charleroi, England were so close to being chucked out. The players and the managers came out and appealed to the fans.
“I don’t think the FA has got a clue how serious this is because it was touch and go last time when they could have thrown out. That was one of the strongest statements I have ever read from Uefa. They normally say ‘it is naughty and we will fine you £20,000’ but I think they could [expel a team] this time.
“I hope they look at the Russians first as the provocation was by the ultras first. The Russians have got to look at themselves and their FA will probably say 'we don’t have a problem, it is the English', but you could see, particularly in the stadium, the behaviour of their fans.
“Now, it is just a minority of English fans and the support of the majority was absolutely brilliant, but we can’t hide away from the fact that England have got some nasty followers.”
Poland 0-0 Northern Ireland
As heatmaps go, this one is fairly one-sided and Northern Ireland are yet to have a touch in the Poland box...

Rio Ferdinand
Former England defender on BBC One
"I see comfort. These three centre-backs and full-backs look comfortable in their strategy. They are asking Poland 'Have you got the quality to get ball in behind us' and they haven't.
"Where Poland are crossing the ball in from wouldn't concern you."
