Thanks for joining us on a night that many of us thought we'd never see.
Yaya Sanogo has scored a goal.
Good night.
Arsenal's injured playmaker Mesut Ozil on Twitter:, external "Well-deserved win, great rematch, qualified for the round of sixteen - what a perfect evening. Superb performance, Gunners!"
Charleschip:, external Tonight showed Arsenal, do know how to defend, just need to have more discipline.
Henry Taylor-Gill:, external Well, we'll qualify second and get knocked out by Bayern or Real. Same old, same old Arsenal.
Arsenal's win dumped Anderlecht out the tournament, despite the Belgians' 2-0 win over 10-man Galatasaray.
However Chancel Mbemba's brace has ensured the Brussels side will be in the Europa League.
Bradders:, external Realistically Arsenal will finish 2nd go out at Round of 16 and will struggle in the PL but will get fourth. Change is needed though.
Prakash Rabadiya:, external Arsenal haters come back and see us when you have been in last 16 for 15 years in a row.
Yaya Sanogo's Twitter handle is 'Yayasanogoal22'. He might have to change that now. Yayasanonegoal22 maybe?
Arsenal manager Arsene Wenger on Sky Sports: "Overall it was a committed game.
"Maybe we were defensively better tonight. We are a team that likes to go forward - sometimes we feel dominate the game and we maybe forget to take precautions to defend. We did that better tonight.
"Alexis Sanchez has given unbelievable fighting spirit. A mixture of talent and desire.
"I like what Yaya Sanogo did tonight. We went long on him. What he did on his first goal is class. Unfortunately, he got injured. Mikel Arteta doesn't look good - it's a calf. I think he will be out for a while.
"The injuries are difficult to take on the chin. We go into many games and we need as many available."
I was impressed by Lukasz Piszczek, Borussia Dortmund's right-back tonight, definitely one out of the Dani Alves school of defending.
Arsenal boss Arsene Wenger has just been on TV saying that midfielder Mikel Arteta could be out for a while with a calf injury picked up tonight.
He was replaced after 67 minutes today.
Full quotes to come.
Thanks to Opta's touchmap, we can see that Santiago Cazorla put in a real box-to-box performance. Impressive stuff from the Spaniard.
Mark Lawrenson, former Liverpool defender, on 5 live
"An awful lot of teams would love to be in Arsenal's position. Apart from Chelsea and Southampton, who can you say has played really well?
"I'm totally convinced Arsenal will qualify for the Champions League via the Premier League again. It's just whether the people at the top think it's time for a change.
"You'd just like the manager to put his hand up and admit he's been a bit stubborn and try to build the team from the back."
Arsenal defender Per Mertesacker on Sky Sports: "It was a solid performance, especially defensively.
"We didn't give them too much. We were solid at the back. We have had a few disappointing results recently. That was a mental test and we are strong enough. We can continue now.
"It's good to score an early goal but over the 90 minutes we were solid and that's the key.
"We had to [sit down and discuss recent poor defensive performances]. After Anderlecht and Manchester United, we dropped mentally a bit. We were even stronger today. We learned form disappointments in the last weeks.
"In the Premier League we have to prove something there. Some vital weeks are coming up."
The stats tell us there wasn't much in the game - Borussia Dortmund had more possession and shots on target, while Arsenal had one shot more than the Germans.
Real Madrid have sealed a 1-0 win in Basel courtesy of Cristiano Ronaldo's goal to mean that Liverpool only need to beat the Swiss side at Anfield to go through from Group B.
Carlos Tevez wrapped up victory for Juventus in Malmo with a comfortable finish after breaching the offside trap. The Italians are in pole position to qualify from Group A with Atletico Madrid who completed a comfortable passage into the knockout stages with a 4-0 win over Olympiakos.
Meanwhile Group C promises to be a fascinating final day with Monaco's surprise 1-0 win in Bayer Leverkusen meaning both those teams and Zenit St Petersburg can go through.
Anderlecht's 2-0 victory over Galatasaray has become academic in Group D with both Arsenal and Borussia Dortmund qualifying.
So Arsenal are through. A victory in their final game at Galatasaray would see them top the group but only if Borussia Dortmund are beaten by Anderlecht, who have nothing to play for.
This is the 15th consecutive season that Arsenal have qualified from the Champions League group stage. They're consistent if nothing else. Very consistent.
Arsenal have been deserved winners tonight and they're into the knockout stages again.
Borussia Dortmund were poor, but the Gunners played well.
Kanayo Umeogu:, external Nice one Arsenal. But remember Dortmund lie 16th in the Bundesliga and are already through to the next stage of the Champions League.
Abdul Said:, external Now who says Arsenal can't defend?
Adrian Ramos almost pulls one back but it's straight at Emiliano Martinez. Two minutes left.
Santi Cazorla is grimacing after being caught by Adrian Ramos. Not what Arsenal fans need to see.
