Club Brugge's Nicolo Tresoldi has als scored five like Haaland.

Manchester City

Manchester City striker Erling Haaland: "I think it is the most (13) I have scored against a club. I have played so many times against them in the Champions League with City and Borussia Dortmund too. Leipzig is a good team so I am happy."

On Elliot Anderson: "He has been amazing, he has had an amazing start to his City career and that is what you expect. You have to come straight in and perform. It is not easy to come in, you need to adapt and new players and a new coach, so he he has been impressive. Respect."

They are just conceding too many easy goals.

I don't think they were really under massive pressure, and in a lot of the games teams get a chance then they score.

Teams are incredibly efficient against them which will probably frustrate Maresca, but the good thing is they have won the game. They probably should have scored more at the end, they had a couple of moments when they could have squared it.

With their 9-1 win at Lens, Como became the first team to score nine goals in an away European Cup match since Feyenoord won 9-0 at Olympiakos Nicosia in September 1971.

A coach said to me when I was younger that it's sometimes better to be lucky than good, and that was the case [today]. I think they were fortunate enough to come away with the victory.

I think Leipzig had more shots on goal than Man City. It wasn't as controlled in any elements of the game when they were out of possession. They didn't create multiple opportunities or sustained pressure in Leipzig's final third.

Slavia Prague have equalled an unwanted record tonight - with a 23-game winless run in the Champions League (and European Cup).

AEK Athens (1989-2006) and FCSB (2006-2013) share that record with the Czechs.

Arsenal are undefeated in their last 19 games in the Champions League, their longest unbeaten streak in the competition.

If you're wondering how that's possible, penalty shootout defeats don't count as losses in these stats...

It was really enjoyable, particularly the second half where both teams were going for it. Leipzig got themselves back into the game by like I said before it was enevitable that Erling Haaland would get on the score sheet.

City just looked a little bit better when they had wingers playing on both sides, but certainty their strengthen in depth was better than Leipzig's.

Como can't quite reach double figures but they grab a ninth against Lens as Matteo Papaccioli chips in before the final whistle.

Manchester United fans will be glad to see they aren't the only ones to have suffered a heavy defeat at the hands of the Italian outfit.

Porto end their losing streak and win their first points in the Champions League this season with a 4-1 victory after Samu Aghehowa scores from the penalty spot.

Aghehowa raced through on goal and only had the goalkeeper to beat, but he was pulled back by Napoli defender Rafa Marin, who gets a red card for his efforts.

Borussia Dortmund emerge as 2-1 winners over Real Betis, while Club Brugge come away from PSV with a 2-1 victory.

Viking grab a late fourth against Sabah to seal their first-ever Champions League victory.

Arsenal are third in the Champions League table, and one of only four unbeaten teams after four games.

Manchester City are seventh - and Aston Villa and Liverpool are also in the top eight.

Manchester United are 17th.

Slavia Prague got some pride back in the second half.

Arsenal made hard work of it but they got their show back on the road in the Champions League and got an important win tonight.

Mikulas Konecny had an effort saved by David Raya right at the death as Slavia took their shot count up to 17 - compared to Arsenal's 12.

That is that.

A tough night for Manchester City who were not really at their best but they've got the job done in Leipzig.

It's all over.

Arsenal dominated the first half but completely took their eyes off the ball in the second period. However they get their win.

Slavia send everyone forward for a free-kick. Seconds left.

Brajan Gruda chips the ball into the box and it just needs a glancing header from Nicolas Seiwald to send it on its way but he can't get there and Gianluigi Donnarumma catches.

City quickly get up the other end and Jeremy Doku can not believe he hasn't scored as he races forward and gets the shot away from six-yards out but he blasts it over the bar.

Should really be 4-2!

Stepan Chaloupek nods a header just wide for Slavia as they push for a leveller.
