If you need any evidence as to how close Ruben Amorim is to leaving Manchester United, his list of replacements is already being drawn up.While talkSPORT understands the Portuguese isn’t likely to get sacked any time soon, even after utter humiliation against Grimsby, fans of the club have very different ideas.GettyFans and pundits are looking through Amorim’s replacements after Grimsby humiliation[/caption]Callers have been blasting their fury down the talkSPORT phonelines following the historic loss against the fourth-tier side in the second round of the Carabao Cup.And it’s not just a case of ‘this guy needs to go’, but plenty are explaining who could do better, and why.Amorim is currently the joint favourite as the next Premier League manager to be sacked at 2/1 with talkSPORT BET.And even he has hinted that it may not be down to the club, saying at his most recent press conference: “Sometimes I want to quit, sometimes I want to be here for 20 years.”However things transpire over the coming weeks, the cold hard facts are that the two-time Primeira Liga has only made the club worse since replacing the unpopular Erik ten Hag in November last year.A worst-ever Premier League finish last season was topped off by a Europa League final defeat to Tottenham, and despite heavy backing in the summer window, things look to have started in the same vein with two defeats and a draw.Stubbornness has been the key word from Amorim’s career, even during his Sporting successes and that’s why caller Carl sees one Premier League rival at the only answer.Eddie Howe – 20/1“I think there’s only one manager. If Amorim’s going to go – and I think he will because managers don’t recover from this sort of situation – I think we’ll just have to break the bank and get Eddie Howe,” Carl said.“He’s got Premier League experience, he’s done a fantastic job at Newcastle.”Questioned as to why Howe would leave his Champions League side for Old Trafford, Carl responded: “It’s United. Benjamin Sesko picked us over Newcastle.Howe lost Sesko to United and could lose Alexander Isak to Liverpool, would Old Trafford prove to tempting?Getty“You think he’s going to say no? With [Alexander] Isak on his way?They’re not going to get Champions League next season, they’re not going to get top five.“They keep losing their best players and they’ve hit the ceiling, unless the rules change.“Under Eddie Howe Man United would win the league, within five years, it took Jurgen Klopp five years at Liverpool.”But what about someone who knows the club and is currently available after being sacked by Besiktas?Ole Gunnar SolskjaerCaller Mike claimed: “I’d have Ole back. Just look what he did against Man City, he had Pep Guardiola’s number, he beat Pep more times than anyone else has. “He got us top three, top two, consistently, when you think where we’ve been the last couple of years. Look at what he did against Guardiola, look at what he did against PSG, look at his record.Solskjaer won four out of nine against Guardiola and finished runner-up in the Premier LeagueGetty“He played a system we could all understand and he won football matches, he beat Liverpool, he beat Man City.”Yet in the short term, talkSPORT hosts think another out-of-work manager may be a better fit to save the season.Sean Dyche“Sean Dyche is a better manager than Solskjaer,” ex-Chelsea defender Jason Cundy said.Arsenal legend Ray Parlour agreed, saying: “Dyche isn’t a bad shout, he knows how to organise teams.”While Breakfast host Alan Brazil responded: “If Sean was to get the United job you’d right away have fans saying, ‘Oh god negative football not the United way,’ I guarantee it.”Parlour answered “You would, but he’d get them organised, everybody would know their positions.Should things spiral out of control, Dyche could be a short-term optionGetty“Everybody would know what their job is and whether he can get the best out of the players that’s the most important thing.”Brazil has other ideas though…Brendan Rodgers – 16/1“Is it too big a job for Brendan Rodgers?” the Celtic fan asked, only to have it put to him the former Liverpool and Leicester manager wouldn’t want to leave Glasgow. “He might do, he’s been very upset because there was no investment before the Champions League,” Brazil responded. “But it’s a totally different game down here, the money they can spend, the players they can get in. Scottish football is buying second rate players.”And what about the former players themselves? Well ex-Red Devil Ben Foster has some thoughts.Rodgers is a winner with Celtic, but also in England with Leicester, while he challenged for the title with LiverpoolSNS GroupGareth Southgate – 4/1“I do feel like they’ve got to go a different way and even if it’s someone like Southgate,” he told talkSPORT of the former England manager. “Just give it a go, somebody that’s going to change the mentality of the players and take a more pragmatic approach because what they’ve been doing just isn’t working.”Southgate is currently the joint-favourite as next permanent Man United, with the other candidate, an FA Cup winner brought up by another listener.Oliver Glasner – 4/1Caller Roy said: “It’s abysmal, Amorim totally out of his depth, he’s been here for a year now.“As far as I’m concerned we need someone like Glasner from Palace.“You have to go for someone like Glasner because you can not see an inch of headway since Amorim turned up to the club, you cannot see anything, he won’t change his system for anything, he won’t adapt.”Glasner is the man of the moment thanks to his FA Cup and Community Shield wins
