"Not conceding is the only positive you can take. Northern Ireland have defended stoutly and Poland have had one opportunity and squandered it.
"I would like to see Northern Ireland sort the midfield out and stop Poland getting in."
Poland 0-0 Northern Ireland
That's it. 45 minutes done.
More chances for Poland so far, with Arkadiusz Milik and Bartosz Kapustka having the best opportunities.

Conor McLaughlin is given a talking to by the ref after a little collision with Artur Jedrzejczyk.
"No more," says Romanian Hategan. I wouldn't mess with him.
Lukasz Piszczek, the Polish right-back who's been very lively, has a go at goal with a looping effort but Michael McGovern catches it.
Poland 0-0 Northern Ireland
Jakub Blaszczykowski goes down like a sack of spuds, with Jonny Evans lingering behind. Once again, the referee waves on. He's not having it.
Poland 0-0 Northern Ireland
Northern Ireland are hanging on. Here's that effort from Arkadiusz Milik a few minutes ago...
Poland 0-0 Northern Ireland
Robert Lewandowski out-foxes Gareth McAuley at the corner flag. The Bayern Munich forward nutmegs his opponent and then earns a corner. Cheeky.
The first attempt comes across and is cleared by Kyle Lafferty. Yes, the NI striker is back defending.
Another corner comes in and Bartosz Kapustka fires a stinging effort which is saved superbly by Michael McGovern.
A corner from the opposite side then causes choas in the box. Green shirts are diving all over the place. It is cleared eventually. Manic defending.

"Northern Ireland have coped with the pressure pretty well but I would like to see us get on the ball.
"There is no quality going into Kyle Lafferty."

Bartosz Kapustka handles the ball and Northern Ireland earn a free-kick just inside the Poland half.
A long ball in from Steven Davis is picked up by Paddy McNair, before Chris Baird tries to send a cross in from about 40 yards out. It loops into the box but is soon cleared.
Poland 0-0 Northern Ireland
Image source, ReutersBartosz Kapustka surges forward and feeds Arkadiusz Milik.
He waits patiently, controls the ball in the box and tries to stick it in the top of the net but it goes over!
Probably Poland's best chance so far.
Poland 0-0 Northern Ireland
To say Northern Ireland have been under the cosh would be an understatement but they are standing firm. The average position of eight Poland players has been in the Northern Ireland half...

"The longer it stays 0-0 the better for Northern Ireland. We are starting to see a little bit of frustration from the Poland side. Robert Lewandowski goes down a second time but the referee doesn't see anything untoward."

Poland striker Robert Lewandowski has gone down twice now, claiming he's been caught by Northern Ireland players, but referee Ovidiu Hategan (great name) hasn't given him anything so far.
Arkadiusz Milik goes for goal with a lofted strike but it's gathered by goalkeeper Michael McGovern.
Poland 0-0 Northern Ireland
Jonny Evans makes another important body block in the box for Northern Ireland.
Poland are pushed back into their own half for once, after Bartosz Kapustka is ruled offside.
Chris Baird floats a long ball into the box, with the hope of reaching Kyle Lafferty, but Wojciech Szczesny rises high and catches it before the Northern Ireland striker can connect.

"The Northern Ireland lads are getting physical with the Polish attackers and that is what you want to see.
"Make sure they don't get a free header and if they do get a header make sure to put them off."

Gerry Armstrong
Former Northern Ireland striker in Nice
"Jonny Evans has come in and produced a great challenge on Jakub Błaszczykowski and it's definitely a goal kick but a corner is given.
"Northern Ireland are starting to settle down and pass the ball a bit better. It's also more encouraging going forward."
Poland 0-0 Northern Ireland
Jakub Blaszczykowski has another corner. He takes his time, as the penalty area is more congested than the M6 on a Friday.
Lukasz Piszczek has a go at goal but it's blocked and then Jonny Evans makes a heavy but well-timed tackle on Blaszczykowski, and another corner is given.
Should it have been a goal kick? The NI fans certainly think so.

Jakub Blaszczykowski whips in a corner for Poland but it fails to reach any of their big lads in the box.
Striker Robert Lewandowski gains possession and tries to twist and turn with some pzazz towards goal but the opportunity fizzles out.

A decent spell of possession from Northern Ireland.
Shane Ferguson sprints up the wing and his only option is to drive the ball into the box and hope for the best, as he's being chased down by the Poland defence.
His cross is easily collected by the keeper.
