Some more quotes from Arsenal boss Mikel Arteta, who says the club could appeal David Luiz's red card.

"I would say yes, let's go straight away, but we have to speak and make the decision (about) what's the best thing to do," said Arteta.

"I am sitting here and I'm expecting to see something and I'm not seeinganything. It changed the game - to play with 10 men for 45 minutes in thePremier League without your centre-back, against this opposition of course it changes the game.

"If there is any contact it's him with David, I don't know if they have adifferent angle to what I have. It's hard enough to win games in the league and those big decisions are like that.

"It was a big decision, if they got it right and can justify they got it right I put my hand up and apologise. The way we lost the game is where it really hurts, it's painful, but I have to take the positives.

"We didn't concede any chances but Moutinho scored a worldie and it's 2-1. Bernd comes out and hits the ball with his hand, it's a clear red card and we're down to nine players and it's almost impossible to win."

With little to do at the back, Harry Maguire's heatmap is firmly situated in the opposition half of the pitch.

Harry Maguire booked for a late challenge on Jack Stephens in the opposition area and it is a costly one.

His fifth booking rules the skipper out of the Everton game on Sunday.

4-0 at half-time is a report writer's dream.

Simon Stone has a cigar out with his feet up at Old Trafford now.

Send us a pic, Si.

United playing without a left-back, Fred has moved to that side but is playing more of an advanced role.

Prakhar Tewari: We had the record of biggest Premier League victory for nearly 25 years. Now time to get that back. Should become first team to score 10 in PL.

Paul Collins: Southampton are going to regret their transfer window dealings. They let players leave with no replacements. Yeah the red card cost them a bit tonight but look at their bench... Redmond aside there isn't one single Premier League proven outfield player. Poor.

9-0 is the Premier League record biggest win.

Will we??

Off we go.

Outcast Donny van de Beek is being unleashed for Manchester United in the second half.

Anthony Martial on too, Luke Shaw and Edinson Cavani withdrawn.

Under way again.

Arsenal

Arsenal manager Mikel Arteta told MOTD: "The team was really on top of the game, we should have been three or four-nil up and in that action [the Luiz red] the game changed completely.

"I’ve seen it 10 times in different angles and I cannot tell you where the contact is. If they have another 50 different angles to watch it, maybe I will be surprised. I looked at seven different angles and I cannot see any contact there.

"The team kept trying, kept playing, kept believing. At half-time the boys were so animated because they believed they could still win the game. Obviously it was an incredible goal from long range, before that they didn’t have any chances. But still we lost and we have to react.

"We hit the post, hit the bar, the keeper made a couple of great saves. We played exceptionally well, scored one goal and should have scored three or four and had more of a gap, but obviously you concede two red cards in the Premier League. I don’t have any [complaints about] the second red card

"The team is encouraging me every day to believe in them and to give me a positive feeling all the time."
