BBC Sport opened a poll after Manchester United's defeat at Grimsby asking 'what next' for manager Ruben Amorim.

More than half of those who have taken part in the poll so far say that he's finished at the club and it is only a matter of time before there is a change of manager at Old Trafford.

At present, 34% believe Amorim needs results quickly or he will be fired, while 14% say he needs more time and will turn it around.

Chris: Hi Phil, once again at West Ham, there is turmoil and mismanagement, whilst Graham Potter must take some blame, most of us feel the problems stem from higher up! What's your take please?

Hello, Chris. A combination of things. Poor recruitment as a result of poor decisions at the top, and also poor managerial choices such as Julen Lopetegui. Potter has also failed to inspire, looking lost and a shadow of the manager who impressed so much at Brighton. He has a reputation as a builder, not a quick-fix manager, so in some ways it is still early days, but results and Potter’s defeated body language and lack of impact mean he is under serious pressure.

There is also serious fan unrest, with Jarrod Bowen – a player totally beyond reproach and the current heartbeat of West Ham – involved in an altercation with a supporter after the Carabao Cup defeat at Wolves. Maybe a busy last few days of the transfer window will help change the course of The Hammers’ season.

More from West Ham fan Callum, speaking on 5 Live's phone-in, on why manager Graham Potter needs to be given more time:

"He seems to be resigned to what’s happening but at the same time I don’t think he’s been given the tools that he would like.

"He’s got one of the slowest midfields I’ve ever seen in the Premier League. They’ve got rid of their best defensive midfielder on loan to Fenerbahce and we’re leaking goals like nobody’s business.

"We got rid of Mohammed Kudus to one of our biggest rivals for £55m when two years ago, we were selling him for £80m-£90m.

"It feels like there’s stuff going on behind the scenes that’s higher up than the manager that’s sort of stifling his ability to get the job done to the level he would like. It looks pretty bleak at the minute."

West Ham's poor start to the Premier League season, with heavy defeats at Sunderland and at home to Chelsea, culminated with a disappointing 3-2 loss at Wolves in the Carabao Cup in midweek.

Captain Jarrod Bowen apologised for confronting West Ham supporters after that cup defeat, but Irons fan Callum, from South London, told Nicky Campbell's phone-in on 5 Live this morning that he does not believe manager Graham Potter is the man to blame.

"Potter needs to be given more time," he said. "The problem is higher up in the club than Potter. I don’t think there’s a manager in world football that would be a quick fix for West Ham.

"You know, David Sullivan, Karen Brady, formerly David Gold, have been in charge of the club for ages.

"All of the ‘progress’ we seem to have made, when you look back on it, almost seems like we’ve fallen into it by luck rather than design."

Graham: Hi Phil, a few years ago, the question was how Celtic & Rangers do in the Premier League. Given current events, do you think they are even Premier League standard? Or where would you predict them to finish in the Premier League?

Hello, Graham. That’s the 64,000 dollar question. I don’t think either would make a single wave in the Premier League in their current position. Celtic and Rangers would bring a huge, passionate fanbase, and they are two great, historic clubs, but as teams, they would be distinctly average in the Premier League without some serious strengthening.

Guy: I know it's very early in the season, but Spurs, Liverpool, and Arsenal are all looking strong. Do you make those three title challengers, or is there another team you'd put in the race as well?

Hello, Guy. Really early days. Brilliant start by Thomas Frank, who I rate incredibly highly, but let’s just put our foot on the ball here and remember how Ange Postecoglou started with a string of wins and euphoria.

Liverpool and Arsenal will be title challengers, of course, whereas I think Spurs should set their sights on the top six – maybe top four. Manchester City had a very poor result against Spurs, but it is always very foolish to write off Pep Guardiola’s team as title challengers, especially after only two league games.

Tottenham Hotspur had reached out for transfer talks around Savinho, but Manchester City have maintained throughout that he is not for sale.

Sources have told BBC Sport the hierarchy at City have now informed counterparts at Spurs that they will not entertain any offers in this window, which is another blow to Thomas Frank's plans after missing out on Eberechi Eze to rivals Arsenal.

Defender Manuel Akanji is of interest to Galatasaray, Crystal Palace and others, with talks taking place around selling the Swiss international - City are understood to want £15m for the 30-year-old.

Sources close to Stefan Ortega have told BBC Sport they are looking at solutions for the German goalkeeper, but an exit is not yet close.

Ilkay Gundogan is another that could depart in the next few days after being left out of the defeat by Tottenham last Saturday and the club would explore sanctioning a sale.

Brighton & Hove Albion

Brighton manager Fabian Hurzeler was asked if Brighton were done in terms of incomings in the transfer window: "I have a feeling. Sometimes it is not so clever to share all the feelings you have in the public but overall I am very happy with the squad. I am in daily exchange with Tony [Bloom], David [Weir] and Paul [Barber] so overall I am very pleased with how the process has gone so far and let's see if they may be any more changes."

Brighton & Hove Albion

Brighton manager Fabian Hurzeler was asked if he was 100% confident that midfielder Carlos Baleba will remain at the club despite interest from Manchester United: "Yes. If there is a number more than 100 - I would even say more than 100. I am confident, yes."

Brighton & Hove Albion

Brighton manager Fabian Hurzeler on team news: "Georginio [Rutter] wasn't involved against Oxford and we would have liked to have had him involved yesterday. For him, it is a close thing. Unsure but he has an option to be available."

We're just going to break away from Manchester United reaction and Phil's Q&A for a few moments, so that we can bring you the latest from today's news conferences and some more transfer updates.

Manchester United will seek to bounce back immediately from their shock midweek defeat when they face Burnley at Old Trafford on Saturday.

Head coach Ruben Amorim desperately needs a first win of the season but the 40-year-old’s top-flight record doesn’t make for great reading.

The Portuguese has won just seven of his 29 matches in charge, drawing seven and losing 15, and his Premier League win percentage of 24.1% is equal to that of Neil Warnock.

Warnock predominantly managed clubs that were battling relegation and the 76-year old won 27 of his 112 top-flight matches in charge of Sheffield United, Queens Park Rangers, Crystal Palace and Cardiff City.

Of managers to have taken charge of 20 or more Premier League games only 48 have a lower win percentage than Amorim and those with a marginally higher ratio include former Leeds boss Jesse Marsch with 25%, ex Burnley and Everton manager Sean Dyche with 27.9% and Steven Gerrard, who achieved a 31.6% win percentage with Aston Villa before he left the club in 2022.

Matt: Amorim seemed very downcast in his interviews post-match. What did you make of this? Is it the right approach, or do you think he should have minimised the result - sometimes the favourite just gets beaten?

Hello, Matt. You can never minimise Manchester United losing to League Two opposition. If Amorim had done that, he would have been slaughtered and rightly so. He had every right to be downcast, but his body language in the shoot-out was awful, cowering in the dug-out, while his post-match comments were those of a man sounding beaten, not just by Grimsby Town but by the job he has taken on.

Last season [Ruben Amorim] said it was the worst ever Manchester United team, well this is one of the worst defeats in the club's history, whether it was on penalties or not.

They started the season losing to Arsenal with an OK display, but had issues over the goalkeeper, then drawing at Fulham, when they played OK.

But now, everybody is going to look at this defeat against Grimsby and I'm not saying the wheels are off at Manchester United but that's a hell of a bad result for Amorim.

His judgement comes into question because if I was Ruben Amorim tonight there is not a prayer I would have made eight changes. I would have played my strongest team, tried to put the game to bed and then made the changes. That was an error from him, in my book.

I think he will struggle to come back from this because people will hold this against him.

The pressure this season for Amorim now is well and truly on, with massive games coming up. They have got Burnley at the weekend then I think they have got the Manchester derby followed by Chelsea. I mean, blimey, if I am him I am officially worried.

Eric: Hi Phil, can you see Manchester United turning this bad form around, and is relegation battle a real prospect if a goalkeeper isn't brought in? Can you see Martinez being the main target with what is left of the window, with Lemmens being a backup?

Morning, Eric. Ruben Amorim must surely change his tried and trusted system to get better results, except that he does not appear inclined to do so at the moment.

And he must surely be considering strengthening in the goalkeeping department. We have seen those links with Emi Martinez and Gianluigi Donnarumma.

Royal Antwerp around goalkeeper Senne Lammens is obviously a target and a very promising 23-year-old, but is he ready to go straight in to such a pressurised situation?

Below is Man Utd's rolling points tally over 38 games (i.e. a season's worth) in the post-Ferguson era - from David Moyes inheriting a team that had taken 89 points from 38 games in 2012-13 to one that has now taken just 40 points from their last 38 games...

You've probably noticed the pretty clear 'plummeting' from the mid-Ten Hag era onwards...that's since the start of 2023-24...

A 3-2 home win v Forest on 26th August 2023 (the one where they came back from 2 goals down) meant they'd taken 78 points from their last 38 games...and it's been literally downhill in the exactly two years since then...unhappy anniversary...

Manchester United’s defeat to Grimsby Town has made headlines around the world. The Red Devils are yet to win this season and head coach Ruben Amorim is under ever increasing pressure, with last night’s League Cup loss arguably the lowest point during his reign.

Most United fans would have predicted a tricky night on the Lincolnshire coast but victory was also expected, with almost £200m spent on a new forward line this summer. A combined £130m started in the shape of Matheus Cunha and Benjamin Sesko, with £65m Bryan Mbeumo appearing from the bench.

Amorim has by far the lowest win percentage of any permanent Manchester United manager since Sir Alex Ferguson, with a return of 16 wins, 12 draws and 17 defeats from his 45 matches so far.

Even the much maligned Ralf Rangnick, who was in interim charge between December 2021 and May 2022, achieved a higher ratio of wins with 38%.

It seems strange to label a game as ‘must-win’ in late August, but Burnley at home on Saturday appears just that for Amorim and his side. Manchester United are unbeaten in their previous 23 Premier League meetings with promoted teams – if that run were to end this weekend it could prove fatal for the Portuguese coach’s tenure at Old Trafford.

Phil: Both Russell Martin and Ruben Amorim are doggedly sticking to a system in the face of embarrassment. Is it time for football tomorrow to move away from the Pep-esque fascination with "having an identity"?

Sticking with a system that is not working, you do not have the players to put into practice, and which clearly does not suit those players you do have, is the very definition of bad management. I have not seen enough of Rangers under Martin to be an authority on this, but results have been embarrassing and – based on what I did see at Southampton – he simply seems incapable of organising a team to defend, leaving them completely vulnerable at all times. He also has too many poor players at Rangers.

As for Amorim, we know the template. It is three central defenders, two wing-backs, two central midfielders, two number 10s and a central striker. He seems stubbornly in denial that this is not working, and, to be brutally honest, if he does not find a system to suit his players and results continue as they are, we know how this ends. And the same applies to Russell Martin.

He is certainly not safe because he brought up the fact that there would be decisions that would have to be made after Saturday's game against Burnley. It felt more as though he was considering his own future rather than Manchester United collectively feeling he was not the right man for the job.

The problem at Manchester United is they have invested a lot of energy to get him there in the first place, believing he was the right man for the job...

There is no magic bullet. Nobody can read into the future so you don't know by sticking with the manager whether you are going to make things worse or things will improve. Nobody knows.

Journalists' reaction to Ruben Amorim's decision to sit in the Manchester United dugout during his side's penalty shootout defeat at Grimsby was universally scathing:

Henry Winter, external: "Manchester United out of a competition before the transfer window has even closed. Amorim and his system under close scrutiny, and manager hardly exudes confidence not watching pens. Good managers adapt. Good managers motivate."

Oliver Holt, external: "Manchester United fans were unbelievably supportive towards, and patient with, Amorim last season. Tonight feels like the night when patience ran out."

Jonathan Northcroft, external: "Are MUFC sure Ruben Amorim is worth it? Worth all the changes/spending/fire sale of best club-produced talents? Results remain poor, morale is still fragile and the football is ugly - seldom dominant and a bad mix of an inherently defensive system and rigid positional ideas."

Darren Lewis, external: "You might not like watching penalties (the fact United were lucky to get there tells its own story) but the optics of Amorim crouching behind his staff during the shootout, on yet another disastrous night for the club, were not great."

Craig Hope, external: "Ruben Amorim sitting in the dugout & not watching his players take penalties hardly screams leader. Even if Man Utd had won, that tells me he’s not the right man for a club of that size. Weak."
