The Republic of Ireland make an enforced change with Jeff Hendrick coming on for the injured Glenn Whelan, who had initially tried to play on.

Toni Kroos then forces a good save from David Forde with a fierce drive. Is there a goal coming?

"You've got to play with the brain as well as the heart," bellows BBC Sportsound pundit Willie Miller.

It's been a frantic, fraught and fidgety opening at the start of the second half but the Scotland defence remains intact.

"What a finish and what a classic counter-attack. He got to the edge of the 18-yard box and what a finish. Northern Ireland are capable of scoring again."

Northern Ireland's version of Gareth Bale (well, according to Richard) makes it 2-0 to his country. Kyle Lafferty has looked dangerous on the counter-attack all night with his pace, power and directness causing problems for the Greek defence.

He collects a ball forward, outsprints substitute Kostas Stafylidis and fires an early shot from the edge of the penalty area into the corner of the net past Orestis Karnezis.

Northern Ireland could be heading to nine points out of nine. At what point does hope become expectation?

Shaun Maloney's free-kick is cleared by the Poles who then launch a lightning counter attack, thwarted by Ikechi Anya before a low cross across David Marshall's goal has no takers in white jerseys. Frustration rains down from the Polish fans inside this pulsating stadium and, for the time being, it remains 1-1.

Manuel Neuer had the quietest of first halves, but the Germany goalkeeper is involved early in the action to deny Robbie Keane after James McClean's pass.

We asked if Podolski could make an impact. Well, he nearly gets the opening goal, but his effort is deflected wide by Republic of Ireland goalkeeper David Forde.

A change at half-time for the Germans with Arsenal's Lukas Podolski coming on for Matthias Ginter. Will he make the difference?

Scotland skipper Scott Brown scored the only goal of the game when the sides met in Warsaw in March this year in a friendly. Will the Celtic skipper have a say in proceedings tonight?

We're back under way in Warsaw, Gelsenkirchen and in Greece.

Scotland manager Gordon Strachan must be happy with his troops at the break. They've come from behind in Warsaw and look dangerous on the counter against the Poles.

Throw in the stat that Scotland have enjoyed 62% possession...

Greece are managed by former Chelsea manager Claudio Ranieri. During his time at Stamford Bridge he was known as The Tinkerman, because of his reluctance to name an unchanged side.

Well, he may need to be tinkering about with his team at half-time to get the hosts back into the game.

Roy Carroll, like Manuel Neuer, will have had busier nights.

This first half has been one of the easiest of Manuel Neuer's life. The Germany goalkeeper has had no shots to deal with, and hasn't even had to marshal the defence for a corner.

It may well be one-sided in the stats, but it is still goalless in Gelsenkirchen.

"Scotland certainly deserving of going in at the interval on level terms, though there have perhaps been a few more unforced errors by men in blue than we've seen recently. Nonetheless, they look largely comfortable and must believe they can score again in the second half."

"Greece are there for the taking. This group is there for the taking. We don't have to go chasing - we just have to pass the ball comfortably. There are goals there."
