Porto 0-0 Barcelona
Image source, Getty ImagesConcern for Barcelona as they are forced into a first-half change. It is Robert Lewandowski who has to go off with some sort of injury. On comes Ferran Torres.
Meanwhile, Lamine Yamal, who at 16 years and 83 days is the youngest player to start a Champions League game, is unfazed by the occasion. He's been producing some brilliant skills and movement.
Newcastle 1-0 PSG
Alex Isak is still being treated, he's having a huge bandage wrapped around his head.
He gets a great ovation from the fans and it looks like he'll be OK to continue.

Image source, Getty ImagesIt is a tight angle for Erling Haaland to shoot.
It was always going to go away form the far post, but he is not in the game at all. You know he is looking to play on the shoulder.
Newcastle 1-0 PSG
Ooh this is a more significant bang to the head. Alex Isak is down and bleeding, after getting clocked while going in for a tackle.
He's getting tended to by the Newcastle medics.
RB Leipzig 0-1 Man City
Erling Haaland, we've not seen much of him tonight (hat-trick incoming).
Suddenly he is in behind but the angle is tight and he sends a shot wide of the far post.
Newcastle 1-0 PSG
Rain continues to pour down in Newcastle.
Beautiful Geordie weather.
In Glasgow, Lazio have equalised against Celtic.

Image source, ReutersWhat about Rico Lewis how well he is performing - it is a brilliant run. It is a fantastic pull back for Phil Foden and that is a magnificent finish. It is not an easy finish, Foden had to adjust his body and he hits it into the ground.
Lewis in the build-up starts the move and gets the cross in and picks out Foden. Deserved for City.
Newcastle 1-0 PSG
Fabian Schar is down after getting clattered in the face by Goncalo Ramos, accidentally.
The Swiss is a big boy, he's back on his feet.

Ben: New-ventus, anyone?...
Anon: Jack Grealish isn't fit to lace Miguel Almiron's boots!
David: Come on Newcastle, get another while PSG are on the ropes at the moment. One goal probably won't be enough.

Paris have come back well and Newcastle have put a lot of energy into it already and must go again.

Now PSG come close, Goncalo Ramos' shot is deflected narrowly wide.
This is superbly entertaining.
Phil Foden (25 mins)
Image source, Getty ImagesIt has been coming!
No surprise that Rico Lewis is heavily involved because he's been having an excellent game.
Lewis starts things off as he plays a one-two with Bernardo Silva before cutting the ball back to Phil Foden inside the box and the England forward produces an excellent finish for his 11th Champions League goal.

Just the start Newcastle United wanted - and Eddie Howe's team are really fired up. Bruno Guimaraes and Dan Burn have both responded with clenched fists and roars to the crowd after steaming into tackles.
PSG have been knocked out of their stride, as shown by Marquinhos' mistake, but they still look a real threat going forward.

A rare attack for RB Leipzig now but Emil Forsberg is unable to get his attempted pass to Lois Openda through on the edge of the box.
Newcastle 1-0 PSG
PSG are wobbling, Marquinhos and Gigi Donnarumma miscommunicate leading to the centre back having to put the ball behind for a corner.
It is played low to Fabian Schar in space at the edge of the area, who sweeps narrowly wide.
Newcastle 1-0 PSG
Warren Zaire-Emery is a very talented young man.
He takes a shot from 30 yards which has Nick Pope at full stretch, but which cuts just wide.
Borussia Dortmund 0-0 AC Milan
No goals to report in the other Group F game, with chances at a premium too.
As it stands, Newcastle are top!
RB Leipzig 0-0 Man City
Image source, Getty ImagesHere comes Phil Foden. He slaloms between three RB Leipzig players but skews his shot wide of goal. He's done the hard work, just the finish letting him down.
Newcastle 1-0 PSG
How do PSG respond to this? Instead of riding out the early Newcastle adrenaline, they have allowed the hosts to settle into a rhythm. That opener was deserved.
Dan Burn makes a solid tackle on Ousmane Dembele which is cheered as if he'd scored the winning goal.

To say that it has come to life, that would not tell half the story. The noise in here is incredible.
That was just what St James Park wanted.
