What a night! Plenty of drama, ups and downs and heartbreak/joy.

More of the same all weekend? We'll be here. See you there. 

England are among the teams in action on Friday night - Roy Hodgson's men have the luxury of a dead rubber as they were already through.

Here's the full list of games:

Liechtenstein v Sweden - 19:45

Moldova v Russia - 19:45

Montenegro v Austria - 19:45

England v Estonia - 19:45

Slovenia v Lithuania - 19:45

Switzerland v San Marino - 19:45

Macedonia v Ukraine - 19:45

Slovakia v Belarus - 19:45

Spain v Luxembourg - 19:45

Germany manager Joachim Low: "It was an unexpected and totally unnecessary defeat.

"In the second half we played a bit negligent. Ultimately, we lacked the ultimate consequence and the last pass. And then we make a single mistake and it is a goal."

More from Gordon Strachan: "You have to hold your hands up and say well done (to Ireland). We have played against Poland and Ireland and not been beaten.

"I am hugely disappointed. After working hard for a year and at the end of the year for something like that to happen in the last seconds of a game...that's a year's work. I can't remember us getting anything lucky. Anything we got has been earned."

Scotland manager Gordon Strachan: "If I'm like the rest of the nation, I am hugely disappointed for the players. The group of lads gave as much as they could give. That's what I see at the moment. I feel a bit sorry for them, to have put so much work in and to have scored two wonderful goals. I am proud of them. They have been a bit unfortunate."  

Malcolm Harvey: A spectacularly Scottish way to crash out. Still, could be worse. We could be English rugby fans...

Germany defender Mats Hummels: "What happened is what happens with teams like Ireland and that is that we had a lot of possession.

"We had our chances but they used their only one. Ireland made the most out of very little. Now we know it can get very tight in the last game and we have to be dominant against Georgia and not let anything happen."

Martin O'Neill totally forgot the word 'play-off' there. His mind went blank. That's what drama can do for you...

Republic of Ireland boss Martin O'Neill: "The players put in a fantastic effort. To beat the world champions is a sensational effort.

"We showed bravery and courage. We had to withstand a lot of pressure, which you'd expect, and we did that.

"We have reached the play-offs now and we can go for it on Sunday now."

So. Just to de-tangle what surely must be one of the most complicated qualification scenarios in football ever, here's where we are in Group D. 

Republic of Ireland and Poland play in Warsaw in both teams' final match on Sunday. 

A draw would leave both teams on 19 points. 

Germany currently lead the group on 19 points, but will be expected to beat Georgia at home in their final game. 

If though, all three teams end up on 19 points, both Poland and Republic of Ireland have better head-to-head records than Germany, and both would finish above them.

As to who finishes higher between Poland and Republic of Ireland if both teams finish on 19 points, here's how it works:

A 0-0 draw in Warsaw means Poland go through - they will have scored more away goals in meetings between the two sides. 

A 1-1 draw in Warsaw means Poland go through - they have a better goal difference of the two sides.

A draw of 2-2 or higher would mean Republic of Ireland go through - as they will have scored more away goals in meetings between the two sides.

Elsewhere, Portugal booked their ticket to Euro 2016 with a 1-0 win over Denmark in Braga.

Joao Moutinho scored the only goal of the game midway through the second half as Portugal ensured they would top Group I. Denmark, who have played their last game, will still qualify if Albania fail to win in Armenia on Sunday.

Windsor Park is still rocking - there will be a good night out in Belfast tonight. And Dublin for that matter!

Northern Ireland boss Michael O'Neill: "The players were outstanding. Right through the team, magnificent, It's a privilege to be here, I'm proud to stand here as their manager.

"How have we done it? I'm not really sure! The players deserve the ultimate credit. We have confidence and belief which comes from winning games. This shows the potential of this team and of football in Northern Ireland."

BBC Scotland reporter Chick Young at Hampden: "Every fan leaving the ground will feel the same. The heart and soul has been ripped from us. This was going to be my final campaign. That's the tin hat on that now. I feel absolutely torn apart and shattered. I won't sleep tonight. People will wonder how on earth that happened. It's always us."

Northern Ireland defender Gareth McAuley: "I've had some highs in individual games in my career but there has been real belief in this campaign.

"I can't put into words what it means."

Republic of Ireland, Poland and Germany could yet all end up on 19 points on Sunday evening...

They need a point against Georgia to be sure, to be sure...

An incredible night of action. Let's recap things:

Northern Ireland HAVE QUALIFIED FOR EURO 2016

Scotland's chances are over, they are out of the picture.

The Republic of Ireland can qualify on Sunday - if they beat Poland. If it's a draw - well we need an abacus to work that one out...
