We had an Ireland win in Luxembourg, some tension in Spain and serious drama in Portugal.
I think that'll do!
Night everyone.
'We are not perfect... but there is more to come'
FT: Luxembourg 0-3 Republic of Ireland
Ireland manager Stephen Kenny, speaking to Sky Sports: "It was a tough game. They play some good football. We felt they can hurt us but we can hurt them and exploit the back four with pace. We lacked control in the first half but we went for it out of possession and left ourselves exposed. But we knew we could score. We created chances and are delighted to win.
"We got in several times. The final pass wasn't quite right. It was pretty open and frenetic. We knew we just had to win the game, get after them and force errors.
"One of the advantages of being U21 manager previously is that I know the character of the players, I know Jason Knight's strength and characteristics. We are delighted to have him.
"Since we lost to Luxembourg and Portugal we are doing well. We know we are not perfect but there are players coming through and more to come. There was pressure on the players and they have responded. They are a pleasure to work with. It is a collective effort.
"I would rather the fans sing about the players than me. I appreciate it but it is about players. Ours have been magnificent over the last few months."
'We had to find a way to win'
FT: Luxembourg 0-3 Republic of Ireland
Ireland striker Chiedozie Ogbene, speaking to Sky Sports: "I'm delighted to score again but I owe it to the team. We came here and got the win and keep a clean sheet against a good team. Knighty spotted me. He came on and changed the game. Three goals away from home is incredible.
"Credit to the fans for coming out here and supporting us. We needed the support. They lifted us.
"We had to find a way to win, We knew what we wanted to do and it was always going to take time.
"This time last year I was in a knee brace. I worked so hard to be here. Stephen Kenny, credit to him for getting me in this position."

Things are going well for some individuals in the Ireland side too...
Chiedozie Ogbene is the first player to score in both
of his first two competitive away internationals for Republic of Ireland since
Stephen Ireland in 2007. Ogbene has more goals in his five senior international
games (two) than he does in 58 appearances in all competitions for his current
club Rotherham United (one).
And having only scored once in his first
20 senior internationals for Republic of Ireland, Callum Robinson has since
bagged six in his last four for his country.
Post update
It was a positive night for Ireland too.
They have now won three of
their last four matches in all competitions - as many as their previous 22
beforehand (W3 D11 L8).
They have also scored 20 goals in 12
internationals in 2021, two more than they scored in 27 games across 2018, 2019
and 2020 combined before this (18 goals).
And they have kept a clean sheet in
four consecutive internationals under a single manager for the first time since
October 2011, a run of eight under Giovanni Trapattoni.

You have to love a full-squad pile-on in the last minute of the last qualifier of a group to celebrate qualification. Mad scenes from the Serbia players and staff in Portugal.

So, they left it very late but Spain are there and Serbia (who left it even later) are joining them. Portugal and Sweden have to go through the play-offs to join them at next year's World Cup finals in Qatar.

Aleksandar Mitrovic (90 mins)
Wow!
Incredible scenes in Portugal as Aleksandar Mitrovic pulls away from his marker to meet a cross and he makes no mistake with a downward header.
He might just have sent Serbia to the World Cup!

Late goal in Spain, anything in Portugal? Nothing yet as substitute João Félix takes on the Serbia defence, doesn't get through but does win a late corner.

Jason Knight cushions a cross from James McClean into the path of Callum Robinson to side-foot into an empty net.

Alvaro Morata (85 mins)
Spain are going to the World Cup!
Dani Olmo cuts in from the left and smashes the ball against the crossbar from range.
The ball bounces straight to Alvaro Morata running in who chips the ball into an empty net. No question of offside.

Another change for Sweden with five to go.
Emil Krafth limps off. On comes Martin Olsson
CLOSE!

Oh was that the chance! I think it was.
Aleksandar Mitrovic, who has been so quiet you'd be forgiven for thinking he was still on the bench, finally finds space in the Portugal defence to leap and meet a great cross but he flashes his header wide.
