Kyle: I hate the lack of consistency in the Premier league. It's an absolute joke. That was never a penalty in a million years for West Ham and how one of the most experienced officials in the VAR booth could send him over is an absolute disgrace.

West Ham United

Asked about the penalty decision, West Ham boss Julen Lopetegui said: "I didn't see it. The players say it's a penalty and the referee says it is a penalty, so I am sure they are right.

"I prefer to highlight that, after they scored, we kept the energy and positive momentum to win the match. I prefer to keep that energy."

Speaking on his Gary Neville podcast, external about West Ham's penalty, the former Manchester United defender said: "It's not right that one. Every team gets a bad decision but that wasn't right.

"The interesting thing was he must have watched it eight times when he went to the monitor. I'm screaming at the TV 'he doesn't think it's a penalty' but then he overturns his original decision.

"I think the pressure maybe of being sent over to the screen by Michael Oliver, a dominant referee, no-one likes to upset their superiors.

"I'm not sure David Coote was anywhere near thinking it was a penalty, and it was a big shock."

I think time has run out [for Erik ten Hag]. I think right now they are just waiting to see what the best option is and what the best next move is for Manchester United.

One of the things you have to think about is, are you going to get a manager just to fill in the gap again or are you now going to find the right manager for the real long-term plan and development, and trying to compete to where you want to be and where the club should be competing, so that's the big decision.

I think for me, the Erik ten Hag era is pretty much over. I think now the big decision that has to be made is, who's next and who's going to fit what the goal and the dream and ambition of this club is.

Anon: 09:02 @Martin - That’s exactly why we don’t see any improvement with VAR. As fans we should be asking for better but as usual, petty bias gets in the way of progress!

It is a surprise [that the referee was sent to the monitor]. I thought we were going the other way. I thought there was that non-interventionist style of VAR. More like what we are used to seeing in the Champions League with the officials there. Unless they absolutely have to [interfere], they leave it to the referee's on-field decision.

So it was a surprise to me that Michael Oliver, one of the best referees in Europe, decided to call David Coote to have another look at that. Of course, as soon as that happens, you know what the result is going to be.

I can understand Manchester United and Erik ten Hag's frustrations, certainly with that, but again they have to look at themselves. They weren't able to take the chances and that's a recurring problem for Manchester United.

Manchester United

Here's what Manchester United manager Erik ten Hag had to say after Sunday's game: "We know, we have to score. We created so many chances, at half-time we should have been 2-0 or 3-0 up.

"But it feels very unfair, an injustice, the way we concede the penalty. There was an incident but it was so difficult to see, and before the season we had the instruction that only with a clear and obvious mistake then the VAR has to interfere. This is definitely not a clear and obvious mistake by the referee on the field."

It's not often I agree with Erik ten Hag but this is one of the few times I will - it wasn't a penalty.

It's one of those where you want your defender to put a presence and a body there. There is a lot going on in such a short moment of time. It's more of a coming together and it's not really a penalty in my opinion - stone cold, 100% not a penalty.

I do feel for Manchester United, it was harshly done. It wasn't a terrific or great performance from United anyway, but in that big moment there, it wasn't a penalty.

What are your thoughts?

Should Michael Oliver have intervened? Did the officials follow their own guidance on potentially overturning the 'referee's call'?

Plenty of you have already let us know your views but please keep them coming.

MOTD2

You can view the penalty incident below and hear the thoughts of Micah Richards and Stephen Warnock on Match of the Day 2.

Richards says: "It's not a penalty. I feel sorry for [Matthijs] De Ligt, [Danny] Ings has sort of jumped into him."

Warnock adds: "It looks clumsy for De Ligt but it's that close, the proximity, what's he meant to do? It's a coming together, it's not a penalty. This is one that VAR has got wrong. I just don't think there was any need to step in on that decision."

There is loads to unpick about Manchester United's defeat at London Stadium, not least the reality that if Erik ten Hag's team had taken all the chances they created in the first half, what happened at the end would not have mattered.

But it is clear Ten Hag will focus on the moment that cost his team a point.

The Professional Game Match Officials Limited (PGMOL) has not changed its guidance to VAR officials since the start of the season, when the Premier League’s chief football officer Tony Scholes underlined the view around 'Referee's Call'.

The guidance is: "'Referee’s Call' really is just an introduction of a terminology to make it clear that the initial decision by the on-pitch official is critical. It's similar to what exists in other sports like cricket and 'Umpire’s Call'.

"The referee’s call should stand unless the VAR, based on readily available evidence, can see without doubt the on-pitch official has made a clear mistake. In the absence of that clear evidence, the referee’s call will stand."

Premier League

West Ham's winner against Manchester United was a penalty scored by Jarrod Bowen. Referee David Coote allowed play to continue after Matthijs de Ligt collided with Danny Ings in the visitors' penalty area.

Michael Oliver, the video assistant referee, then advised Coote to look at the pitchside monitor and after reviewing the incident numerous times, Coote overturned his on-field decision.

The Premier League later explained on its Match Centre account on X, external that there was "sufficient contact" to award the penalty.

"The referee did not award a penalty to West Ham for a challenge by de Ligt on Ings," it said.

"The VAR deemed there was sufficient contact on Ings' lower leg and recommended an on-field review. The referee overturned his original decision and awarded a penalty."

The question is - after that, are we any wiser about Arsenal and Liverpool’s hopes of unseating the champions Manchester City?

What we do know is that even without Rodri long term, and without Kevin de Bruyne at the moment, and without Kyle Walker, Jeremy Doku and Jack Grealish on Saturday, Manchester City are the Premier League’s only remaining unbeaten team this season and lie one point ahead of Liverpool and five ahead of Arsenal with almost a quarter of the league season played.

We felt we would know more about Liverpool’s credentials after Sunday, but I’m not sure we do. However, the feeling was that after the last international window we would find out more what Arne Slot’s team are made of and they’ve come through a testing run of Chelsea at home, Leipzig away and Arsenal away with two wins and a draw.

For them though, those tests keep coming match after match with two games against Brighton, then Bayer Leverkusen and Aston Villa, plus Real Madrid and Manchester City not long after that.

For Arsenal, yes they have been severely hit with absentees in defence and on Sunday they ended up with a back four of Thomas Partey, Ben White, Jakub Kiwior and Myles Lewis-Skelly. None of them are first-choice in those positions, and it was then Liverpool found a way through to make it 2-2.

There will be an anxious wait now for Mikel Arteta to find the extent of the knee or ankle problem that meant Gabriel could not run and forced him off. What is sure is that Arsenal will have to make do and mend, and with tricky away matches coming at Newcastle and Chelsea, they cannot afford to slip much further behind.

Arsenal have only lost one of their opening nine Premier League games this season, and despite taking points off previous leaders Liverpool on Sunday, they're now five points adrift of defending champions Manchester City.

Here's how the top half of the table looks after Sunday's games.

Phil McNulty
BBC Sport chief football writer at Emirates Stadium

Arsenal have been looking for every vital sign that this is the season when they will finally make the leap from pretenders to Premier League champions – but the indications are already ominous.

Mikel Arteta’s side showed plenty of guts in defensively reduced circumstances in the 2-2 draw with Liverpool at Emirates Stadium, but there will be deep frustration at getting one point rather than three.

Arsenal had victory in their sights as they led through Bukayo Saka and Mikel Merino’s goals with only nine minutes left, only to fall victim to a sweeping Liverpool counter attack and Mohamed Salah’s equaliser.

There was plenty to admire in Arsenal’s performance, delivered despite the handicap of losing key defenders Gabriel and Jurrien Timber in the second half when holding that slender lead, to go with the absence of suspended William Saliba and injured Riccardo Calafiori.

These are the mitigating circumstances, but for Arteta and his players in the ruthless business at the top of the Premier League, the league table now bears a worrying look.

The Gunners’ draw with Liverpool helped only Manchester City, now established in the familiar position as leaders, and with margins for error wafer thin when trying to overhaul Pep Guardiola’s sky blue machine, a five-point gap to the top is already reaching the point where it cannot be allowed to get any wider.
