Liverpool were the better side, but boy did they make their fans sweat for it tonight.

There were mistakes there from the Liverpool defence, those two goals they conceded - it was too easy to pass through them.

If you take Virgil van Dijk out, there will be weaknesses.

Manchester City

Manchester City midfielder Jack Grealish to BT Sport: "I loved it. I've been waiting a while. The past few weeks, I couldn't wait for this game. It's a great night.

"It was one of those games. It had absoutely everything. In the end we're delighted to get the win against a good team full of energy and young players.

"I'm delighted to come away with the three points - and the goal and assist.

"The ball came to me and when I'm in that position, running into the area I'd back myself one on one against anyone to have a go and it paid off. I had a few in the first half that were blocked.

"I went to check the result from the other game [Club Bruges 1-1 PSG] and it shows anything can happen in the Champions League. It's why it's such a wonderful competition.

"With the music and everything [before the game] it was so nice."

Liverpool

Liverpool defender Andy Robertson, speaking to BT Sport: "It is one of them. Enjoyable for the neutral and I am sure the fans in here loved it by the time we got ahead. First half an hour we blew them away. Then we got sloppy and stopped doing the things we were doing really well. We let them back into the game and walk in at half-time thinking 'how have we let this happen?'

"It was important at the start of the second half to come and forget about the last 10 minutes and come out and do what we did for the first half-hour.

"We got an early goal and then what a strike by Hendo and then we were able to see out the game. They didn't really have chances after that which is really pleasing. We know how tough the Champions league is and how important it is to start with three points.

"There wasn't much to solve. It was the last 10 minutes the gaps in midfield got too big. They found spaces between us, which is always dangerous, especially when the wingers start to go inside. As soon as we closed the gaps there was no room to play.

"When you play in this tournament it is against good teams. We need to be smarter. Really tough but we managed to come out second half, play our football and enjoy it again."

This is the highest scoring Champions League match of Pep Guardiola's managerial career. It was his 137th game in the tournament.

It must be good to know that you can score six goals and have them come from a host of different players.

They'll take the three points and the fact that that leaves Man City top of the group.

Porto end the game with 10 men as Chancel Mbemba is sent off - a straight red - for a fouling Antoine Griezmann and preventing him running clear. Was he the last man? The referee certainly thinks so.

Atletico do not have the time to capitalise, though. Luis Suarez went close with the free-kick, but cleared the bar by inches.

So Liverpool lead Group B curtesy of that thrilling win over Milan.

That's how Lionel Messi's first ever Champions League appearance for a side other than Barcelona went.

All over in Portugal as Ajax striker Sebastien Haller becomes only the second player ever to score four goals on his Champions League debut.

He only had five shots.

They're still playing in Madrid. Into five minutes of injury time. This will be a fine point for Porto against the Spanish champions.

It's all over.

Manchester City score six goals in a Champions League game for the third time in less than three years.

It was a very entertaining game, although City had to work for it.

Rodrygo's late, late goal gives Real the win. Inter gave as good as they got. A bitter pill to swallow.

A roar greets the full-time whistle.

Liverpool are up and running with a win in another classic game with AC Milan.

Seriously, do these two know how to do normal matches against each other?

Riyad Mahrez beats his man and forces a save as City look for a late seventh.

Joel Matip rises to head away. Thirty seconds to go.

It's all over.

Not the full PSG debut Lionel Messi would have hoped for. He hits the post and gets booked as they are held by Club Bruges in the Champions League.

Kylian Mbappe was injured too.

If Liverpool were to lose or even draw, they'd be kicking themselves. It's probably the right result just now.

Man City have scored six - Liverpool could easily have scored six tonight.

The Reds are closing in. Just the one added minute to go.

Real Madrid have nicked this right at the death!

What an impact too from substitute Eduardo Camavinga. The summer signing is there in the box to volley a pass for Rodrygo to finish on the volley.

Four minutes added on in Manchester.
