It will be a huge week [if Man City get a result against Arsenal on Sunday].

But Pep Guardiola’s choice of team was very much on Napoli, not looking at the weekend, but he was able to make those changes late on because the game was done.

They really played well, they were patient, they moved the ball around, their recovery runs limited space and turnovers are so important to the manager because defensively they have been a little bit of a weakness there. So a real positive, two good results [after beating Manchester United] and now a huge game at the weekend.

Jeremy Doku’s looking excellent and his goal was fantastic as he stepped inside and completely passed people. Phil Foden, we missed him last season but he had a Man of the Match performance. A real positive night for Pep Guardiola.

Pep Guardiola's 17th campaign as manager in this competition began with a win as City aim to make up for last season's disappointment when they failed to make the top-eight and were knocked out at the play-off stage.

City's recent form in this tournament has been poor, losing five of their past seven games before Napoli.

And they will have felt at times in this contest that they were going to be left frustrated as they saw ex-Manchester United academy man Milinkovic-Savic repel everything they threw at him.

But with Haaland in their side, City have a player who knows where the back of the net is and seems intent on proving a point, taking his tally to six goals in five club games so far this term.

His headed effort from Foden's glorious pass just before the hour mark drew relief all around the stadium.

Congrats on the 05 goals, Erling.

Manchester City's Phil Foden, who assisted Erling Haaland's 50th Champions League goal, speaking to TNT Sports: "They were a nightmare team to breakdown. I thought we were pretty clever and didn't give away too many turnovers.

"The first half was a bit frustrating. I wasn't getting too many touches between the lines. Erling [Haaland] is always going to make that run. It's just about getting that connection.

"He seems to break every record going. It's unheard of what he's doing. What an unbelievable player."

City boss Pep Guardiola on Erling Haaland's goalscoring: "What can I say? The numbers speak for itself and how lucky we are to have him. Just congratulate him.

"[Ruud] Van Nistelrooy and [Robert] Lewandowski but also the two monsters Cristiano [Ronaldo] and Lionel [Messi] in the past 20 years and Erling is there.

"In terms of goals he is unbelievable. “There’s no danger if he can play 10 more years. If he maintains this progression, absolutely [he can break the all-time record].

"It’s a question of [him] playing a lot, experience, more important goals and his mentality as well."

Another game, another where a goalscoring record has been obliterated by Erling Haaland.

Manchester City were being frustrated by the 10 men of Napoli in the Champions League on Thursday night, but up stepped their ever-reliable talisman to send them on their way to another victory.

The Norway striker nodded in from Phil Foden's delightful pass to score his 50th goal in the competition in just 49 games - the quickest player to reach that milestone.

The rapid manner in which the 25-year-old reached his half-century is highlighted by the fact that former Manchester United striker Ruud van Nistelrooy previously held the record at 62 games.

Haaland knew what he had achieved, celebrating with a grin on his face and holding up five fingers on one hand and a zero with the other towards the cameras.

Manchester City forward Erling Haaland scored his 50th goal in the Champions League on Thursday evening.

It was just his 49th appearance in the competition, meaning he reaches the landmark faster than any other player - by some margin too.

He reaches the half century of goals in at least 13 appearances fewer than any other player in the competition's history, surpassing Ruud van Nistelrooy who did so in 62 games.

Big fan then, Stuart?

Anyway, time is ticking and we've got another striker to talk about before the first of our Premier League news conferences gets under way.

Erling Haaland. He's good at the football, isn't he?

Nick Woltemade scored the winning goal on his Newcastle debut against Wolves last weekend ago but found himself on the bench for over an hour against Barcelona.

The Germany international came off with cramp in the Wolves game so Eddie Howe chose not to risk him from the start on Thursday - and was not in the mood to contemplate would things might have gone differently if he'd started Woltemade.

"I can't live in that world," Howe said. "I have to make decisions for the benefit of the players sometimes.

"It was a really difficult one for Nick. Any player would want to start the game, but I have got to try and manage him into the team and try and make sure he stays fit. That was always at the heart of this decision."

Instead, it was Anthony Gordon, who is in the midst of a three-match domestic ban, recalled to play up front.

The former Everton man did score Newcastle's late consolation goal, albeit that came after he had moved out to the left following Woltemade's introduction.

That he did, David.

But do you think things could have been different had Eddie Howe started with new striker Nick Woltemade?

Here's what the manager had to say about that decision...

Seven matches to come, they're not going to be playing the Spanish champions every time.

A little bit like two years ago in the Champions League for Newcastle, there were some great memories and moments, but in the end it was good but not quite good enough. And tonight that's the case.

While the night eventually ended in defeat for Newcastle, there were plenty of reasons for optimism for Eddie Howe's side.

Barcelona dominated possession as you might expect, having the ball 64.5% of the time at St James' Park, and had 19 shots to Newcastle's 10, but it was the home side who recorded the higher expected goals.

Newcastle's xG was 1.46, slightly higher than Barcelona's 1.31, and the hosts created as many big chances (2) as the Spanish champions as well.

But when the opposition forward slaps the ball in off the bar from 25 yards, there's not a whole lot you can do...

It was set up to be one of those "magical" nights as Eddie Howe termed it.

"Back in black and white," the AC/DC-themed banner screamed in the East Stand before the game. It was accompanied by a huge tifo of Monty the Magpie, the club's mascot, standing in between two amps.

Newcastle were back in the Champions League – and they were not about to quietly take their seat at Europe's top table as they faced Barcelona, the five-time winners.

Among those watching on was Tino Asprilla, who scored a hat-trick in Newcastle's 3-2 win against Barcelona in 1997, and Sir Bobby Robson's son, Mark, who "wished Dad was alive to be there" and see two of the clubs he managed meet.

Their attendance, and link to a previous era, served as a reminder of just what is possible on these nights where the stadium shakes and atmosphere tends to be at its febrile best.

The current crop needed no reminding of that, of course, after blowing Paris St-Germain away at St James' a couple of years ago.

Nick Pope, Kieran Trippier, Fabian Schar, Dan Burn, Bruno Guimaraes, Sandro Tonali and Anthony Gordon also started that night. No wonder, then, that Burn called on those around him to "make this PSG 2.0".

However, there would be a different outcome this time.

Unlike that 4-1 victory, this was a night when Newcastle did not take their chances as record signing Nick Woltemade watched from the bench for over an hour.
