Anon: People moaning about the extra time should remember the players cause the extra time. We are getting the actual amount of football, as fans, we pay for and it shouldn't be grumbled about.

Anon: Offside should really come down to clear daylight between attacker and defender, or you get what we have now, size 10 boot offside because the defender is a size 9. Absolutely ridiculous to carry on with the law as it is now.

Mike: I'm a Utd fan, they weren't lucky. We are going backwards and Arsenal deserved the win. Our start of the season is worrying, yet again. And with news the Glazers may be staying, we'll only get worse.

A clip has emerged online of Manchester United defender Victor Lindelof limping out of the Emirates Stadium following his second-half substitution in the loss against Arsenal.

Could the Sweden international be the latest name on what is becoming a lengthy injury lost for Erik ten Hag?

Manchester United boss Erik ten Hag, speaking to MOTD:"I think we deserved to win this game but you don't always get what you deserve.

"I look more at how we step up and if you see from the Wolves game to this game there is big progression. Tonight was a team, I am really happy with this performance and the progress of our performance.

"We did well, we make progress, stick to the plan and believe and in the future we will win games like this."

On Arsenal's second goal: "It can't be that this goal is given. It was a clear foul."

• Manchester United haven’t won any of their last six Premier League away games in London (drawn two, lost four), their longest such run since 2015 to 2016 between the spells of Louis van Gaal and Jose Mourinho (also six games).
• Martin Odegaard netted his 25th Premier League goal for Arsenal, while he’s now scored more league goals than any other Gunners player since the start of last season (17).
• Manchester United’s Christian Eriksen registered his 75th assist in the Premier League, moving ahead of Thierry Henry (74) and into fifth for most assists by overseas players in the competition’s history.

More from Arsenal's Declan Rice to Sky Sports, speaking about Alejandro Garnacho's ruled-out goal for Manchester United: "It's the fine margins of football. We go up the other end and I score then Gabi [Jesus] seals it. It's just the margins that makes the results and in the end end we come through with the result."

On the love from the Arsenal fans: "It's good. As a person you feel a little bit embarrassed but I really appreciate the love they have shown me so far. I just try and enjoy myself."

The importance of the win: "I think if we are being honest, Man City have won four out of four. If we didn't win today, we would have been five points behind. To win that today was a must-win. To start with a couple of wins and a draw is good.

Are you more comfortable as a number six or a number eight? "I am comfortable in both roles. I like the six role but I have been learning the eight role in training. Wherever the manager wants me to play I am always going to give 100 per cent."

On his goal and ambitions for the future with Arsenal: "It is so special. Just to see it again. Like I said, I can't control the price. But when I came here I tried as much as possible to block that out and I want to be consistent. I have started life at Arsenal well but I have so much more I can do."

Arsenal goalscorer Declan Rice speaking to Sky Sports after the Gunners' victory over Manchester United: "I think as an outsider looking in watching Manchester United and Arsenal you understand the heritage, you understand this game and what it means to the fans and before the game I was really focused and knew what this game meant and wanted to give it my all."

On his goal: "We were knocking at the door with the corners I think I controlled it with my chin and then scored. It was such a special moment. The old me would have probably set that back for a cross but last minute of the game there was fine margins."

On his price tag: "I think of course Arsenal is a massive club and you feel the pressure but I try to put in performances. I am eager to learn and improve and we want to push to the next level.

"Everyone's been amazing. I like to have a laugh and speak to people and I have settled in well. Everyone has made me feel welcome."

Arsenal

Arsenal boss Mikel Arteta, speaking to Sky Sports: "We work and do everything we do every day for moments like this. This is sport at the top level, it is about the small margins. It could have gone either way.

"I am really happy obviously. They are a great team, really well coached and they make life difficult for you. When we gave the goal away that we did you are always up against it and in the Premier League that is dangerous."

On Declan Rice: "He was outstanding, but the whole team was as well. Rice gave us the momentum in the moments the team needed it.

"It is a beautiful thing how these turn around and we won the game.

"We have been so dominant. Against Fulham it was a similar story. The team deserves more. When I see a team with that will to win, the eagerness to go and go, it is beautiful."

Manchester United and Newcastle United came third and fourth respectively last season, but find themselves 11th and 14th after the opening four games of this campaign.

Manchester United captain Bruno Fernandes, speaking to Sky Sports: "It is always tough to lose the way we lost. We conceded the late goal after trying to get the draw.

"They are a good team, they created a lot of problems for us. It was a good game for both teams but they got the points in the end.

"I felt the game was balanced. They had some spells on the ball but we wanted them to have that, we knew we could create the danger on the counters.

"It is what it is, if it is an offside we can't get on that. It was a good game, I am disappointed by the result, but the performance of the team, the passion was there. If we keep doing this consistently we will get results.

"It is 11 v 11, home or away doesn't change anything. We had a really good game, it wasn't perfect as we didn't get the win but the spirit was right, the mentality, the desire, everyone doing the job the manager asked for.

"Sometimes the details change the game. It is not perfect to lose but I think we can take a lot of positives from this game."

Wins today for Liverpool, Crystal Palace and Arsenal leave them third, seventh and fifth respectively.

Gutted United fan: Lucky. Lucky. Lucky. Gunners.

Andrew: Arsenal deserve the win as they were better in the 2nd half but I miss the days when the attacker had the benefit of the doubt when it came to offsides. The current rule isn't in the spirit of the offside law. Garnacho is level to the naked eye and to disallow goals like that ruins football.

Victor: Arghhhhhhhhhh! That hurts!

Arsenal captain Martin Odegaard speaking to Sky Sports after the win over Manchester United: "I love to play at home with the fans and the atmosphere is unbelievable. I am thrilled to come behind and very, very happy.

"It's the best feeling in the world. This is what we play for. To give them something back and how they support us and it is amazing to give them this back."

On the drama-filled late stages: "It was mad. I don't know what happened but Gabi [Jesus] did so well in the end and scored a great goal and we got the win.

"All the games are like this now and you have to be prepared to play 100 and 105 and 110 minutes. We did great and I am very pleased to win."

On the upcoming international break: "Straight to Norway now and it's going to be great to go there and see the boys as well."

Mike: Once again the extra amount of extra time completely changes how a game looks. These results wouldn't exist in any other season.

Paul: May I say that’s a great result for Arsenal.

James: Arsenal celebrating like they won the league against a very poor United side. I think both these sides just aren't going to do enough this year.

Declan Rice applauds the Emirates crowd while Ice Ice Baby rings out around him over the Emirates sound system.

Big fan of that, to be fair.

Matt: Oddly that was Utd’s best performance this season. For 90 minutes.

Jasper: Every article I've read has mentioned Onanas distribution & comfort with ball at his feet - a goalkeeper's most important job and always will be, is to keep the ball out of the net.

Suliamon: We just watched a movie full of emotions in added time. Hollywood make this movie.

This match never disappoints.

Arsenal get the victory amid jubilant scenes at Emirates Stadium.

Marcus Rashford put United ahead, Martin Odegaard equalised 35 seconds later. Arsenal thought they had a penalty, which was then overturned, Manchester United thought they had gone ahead only for VAR to say it was offside, then two goals deep, deep into injury time from Declan Rice and Gabriel Jesus seal the win.

What a game.

That penalty decision that did not go Arsenal's way is long forgotten. It is bouncing here.

It's just a breakaway. Manchester United throwing everything forward and Viera plays it to Jesus and he keeps his composure and slots it home.

Alan: Utd have been very good in this second half and did not deserve that mugging. Tough times.

Anon: Speaking entirely as a neutral in this, being an Arsenal fan must be extremely stressful.

Vincent: Mate, does Arteta run a takeaway because he is cooking with Rice!

A long throw in the box from Manchester United, but it is cleared.
