A bright start to say the least! Sergio Aguero should have a penalty as Shkodran Mustafi pulls the striker down to the turf as he attempts to get onto a Kevin de Bruyne through ball.

Great start. There's a bit of a scramble and the defence were dawdling. Aguero does what he does best. Great ball in and an even better header.

Leicester City

Leicester manager Claude Puel, speaking to Sky Sports: "It's crazy. At the start we don't believe enough in our quality. Afterwards we play with intent and we can hurt teams like United. But it's a big disappointment because we found good quality in the second half with a lot of chances to come back.

"The first thing is we have to take responsibility. It was not a fantastic start from United either but we didn't take responsibility. We played backwards or laterally without playing forward, without pressing and without putting them under pressure. It's a shame."

On the decision to take James Maddison off in the second half: "I wanted to give more energy. We had other possibilities on the bench. I wanted more desire and to push the team. It was difficult to recover the ball and we needed to try different things to continue to create chances."

Is he worried by three straight home defeats? "My only concern is this game. There's a lot of frustration because we had all the possibility to get at least a draw. It's not a fair result because we had all the chances. It's too difficult always to chase the game and we are not happy about it."

The players are out now, almost time to go. Can Man City bounce back from their defeat by Newcastle and keep the pressure on Liverpool.

Pep Guardiola and Unai Emery exchange pleasantries.

Arsenal are the only side yet to keep a Premier League clean sheet away from home this season.

They have lost 11 of their last 19 away league games (W5, D3), with their sole clean sheet coming in a 1-0 win at Huddersfield in May - Arsene Wenger's last game.

Arsenal are winless in their last 20 league games away to the other sides in the 'top six' since a 2-0 win at Etihad Stadium in January 2015, and have lost 10 of their last 12 such fixtures.

Manchester City boss Pep Guardiola says he still believes his side are the best team in Europe.

“I believe it,” said Guardiola. “Definitely. I love them, I trust them, I say so many times. I believe it.

“It is an important week for us, but after this week if we are still there then next week will be there too.

Managers are sitting watching our games and saying wow how good we are.

“This is the best way to put on pressure on our rivals. That is what we have to try to do again.”

Manchester City have lost four of their last nine Premier League games, as many defeats as in their previous 72 (W56, D12).

They have been beaten in three of their last seven Premier League games when they have scored first - they had lost just three of their previous 96 matches after taking a 1-0 lead.

Manchester United

More from Manchester United boss Ole Gunnar Solskjaer, speaking to Sky Sports: "Our attitude was spot on. There are a couple of bruised noses and knees.

"It is supposed to be like this. There are three points on the line. Our lads sacrificed everything they had. They know they can do better than this but a clean sheet is always a foundation to build on."

On Alexis Sanchez: "He worked really well defensively. He is coming and improving all the time."

Manchester United

Manchester United boss Ole Gunnar Solskjaer, speaking to Match of the Day: "Leicester got in a few dangerous positions, David de Gea made a few great saves and blocks. We could have done better higher up the pitch in terms of defending but we deserved the three points I thought.

"David [de Gea] is very patient in his positioning and reads the game very well - he doesn't gamble.

"That pass by Paul Pogba is great and the control by Marcus better. Football is a game of mistakes. Our lads, when we make mistakes, they were fighting for the ball and giving their all."

Manchester United

Manchester United forward Marcus Rashford: "We keep trying to improve. The last result [2-2 draw against Burnley] wasn't what we wanted and we need to improve. It was a different game with difficult challenges so to get the win was very good.

"Time and time again Paul Pogba provides opportunities for the team. If we can get him free he'll find you.

"I don't think anyone grows up wanting to be just a striker nowadays. The game's changed and you want to be able to play everywhere - left, right, number 10. My career so far has helped me in that."

Pep Guardiola isn't panicking. "It sometimes happens." That was his calm response after the surprise defeat at Newcastle when Manchester City were sloppy and static.

The title race isn't over. Liverpool look nervy as leaders. But if City lose this, Pep might have to concede.

On paper, it should be a fourth top-flight win on the spin against Arsenal for the first time in 82 years.

Sergio Aguero has seven goals in 11 games against the Gunners. Guardiola is also unbeaten against Unai Emery, while Arsenal haven't kept a Premier League clean sheet on the road this season.

They also haven't won in 20 away games at established top-six opponents. I can't see that run changing. City won't slip up again.

I am going to go with City to bounce back here. Yes, their whole team was flat against Newcastle on Tuesday but in my experience that just makes it easier to lift them collectively.

Every team puts in poor performances sometimes, and nobody really knows why, but I don't think it is a sign that City are about to struggle.

Liverpool may not have taken full advantage of Manchester City's shock slip at Newcastle United - but the bottom line is that the reigning champions have allowed Jurgen Klopp's side to extend their advantage in the title race.

The margins for error are minimal so victory against Arsenal today is essential, although the Gunners have huge incentives of their own after Manchester United's win at Leicester City made the fight for places in the top four even more intense.

Everyone is trying to work out how City are going to line-up today. This is what Opta reckon - a 3-2-4-1.

You might notice some of the people in the graphic line-up are not exactly even. That's because our graphic system doesn't seem to even recognise this as a formation so I had to drag them round myself.

Here's how the top of the Premier League table looks. City dropped down to third this weekend - they could end it two points off top... or eight points off top if they lose and Liverpool beat West Ham tomorrow.

Arsenal dropped down to sixth following Man Utd's win.

Arsenal boss Unai Emery will not adopt the tactics which saw Newcastle beat Manchester City last weekend.

"Usually Manchester City, in every match they impose their style," he said.

"You want to impose your style, you want to play with your personality, but sometimes you need adaptation - more or less, it depends on the opposition.

"It is very difficult to break their style and impose yours. When a lot of teams play with a very deep block, it's because they need to play like that and can also have chances to win.

"But usually you can play 10 matches against Manchester City - maybe Newcastle, maybe Crystal Palace, maybe us as well - you can lose 10 times playing the same, or maybe lose seven, draw two and win one."
