Manchester United’s season is all but over with defeat to Brighton in the FA Cup effectively ensuring they won’t win a trophy this term.For the first time since 1981/82, the Red Devils have been knocked out of the two domestic cup competitions in the first round they entered.It was another afternoon to forget at Old Trafford for Man UnitedAFPMan United will now only play 40 games this season, which is the first time they’ve done that since 1915, when the First World War was happening.Darren Fletcher is in interim charge at the moment and has seen his side draw 2-2 with Burnley and crash out of the FA Cup.Although talkSPORT understands Man United are more likely to appoint Michael Carrick until the end of the season despite Ole Gunnar Solskjaer appearing as the frontrunner earlier in the week.But one one Man United fan believes that the club made a mistake sacking Ruben Amorim in the first place and if the Portuguese was still in charge, they would still be in the FA Cup. Speaking on The Final Word with Majestic and Pardew, Mabs said: “If Ruben Amorim was in charge today, we would have won that match.“Brighton’s manager [Fabian Hurzeler] said that Ruben Amorim is a world-class manager.“We’ve sacked a manager who won at Anfield, at the Etihad Stadiu and the Emirates Stadium.“He took us to the Europa League final, just the way [Jurgen] Klopp took Liverpool to the Europa League final.“We should have given Ruben until the end of the season. This sacking just made no sense.“He probably wanted a player like Antoine Semenyo, and they came out and said, ‘we can’t get that player, and we aren’t going to give you any funding for January’.Amorim wasn’t afraid to call out his players time after timeGetty“So, I can understand the frustration. If you want Man United to compete at the top level, you want them to spend.“You also can’t be telling a manager or a coach how to be playing.“I saw a video of Wilcox saying he can’t help telling managers how to coach.“The idea of Man United of old is gone, you need to let that go.”The disappointment at Old Trafford continuesPardew’s on Man UnitedMeanwhile, former Newcastle and Southampton manager Pardew thinks the problems lie with the playing squad.Money was spent in the summer on a new goalkeeper and front three but other areas of the pitch were ignored.And Pardew thinks that is an issue for whoever is next in the Old Trafford dugout.“You’ve got to have a playing staff that warrants wearing that jersey,” he said.“When I look at that Manchester United team, particularly at the back, there is no foundation for me to build on, in terms of a back line where you can be solid.“I think Spurs’ back four is better than Man United’s, whoever is fit. I think that is a problem that they didn’t address last summer. At the top of the pitch, they addressed a little bit.Man United can technically still win the Premier League but they are 17 points off the paceGetty“Obviously, [Matheus] Cunha, who I thought was a bit disappointing today. [Bryan] Mbeumo is away, and [Benjamin] Sesko was okay today.“But there is still so much to do behind the front three. The midfield, the back four, the goalkeeper is only just finding his feet. There are a lot of problems for whoever the manager is.“Whether it’s Solskjaer, Fletch [Fletcher], Amorim, if he’d stayed. There are a lot of problems in that squad in terms of balance and cohesion and fight.“The one thing whenever you played against Man United, they always had fight in them, and it was always difficult to out-fight them, and that was the only way you were going to win because you couldn’t technically beat them.“But those days are long gone, and I thought Brighton were fairly comfortable.”Wilcox has been accused of meddling and admitted that is something he likes to doGettyA messThere is no question that Amorim’s results weren’t good enough, and no matter what statistic you look at, they don’t make pretty reading.But one thing was clear from any time he spoke about the club, he was trying to make fundamental changes to the attitudes and culture.He understood it would take time and effort to try and change things, but ultimately, he never got it.Of course, things unravelled quickly following his outburst after the 1-1 draw against Leeds United.A lot of his departure revolved around an explosive meeting held between Wilcox and Amorim over the second half of the season.The discussion quickly turned volatile after Wilcox is said to have name-dropped Antonio Conte and Thomas Tuchel and asked the 40-year-old to be more tactically flexible.He was also informed that funds brought forward to try and buy Antoine Semenyo wouldn’t be made available to strengthen other areas of the squad.The relationship between Amorim and the club became basically untenable, and the former Sporting Lisbon boss was dismissed.Man United are still in the race for Champions League football, but they need a resetGettyWhat happens next?Since Amorim’s departure, there have been a lot of calls for the next appointment to be someone who knows the club.And talkSPORT understands the board are going to listen to those suggestions from ex-players.Michael Carrick and Ole Gunnar Solskjaer have been interviewed face-to-face with a view to taking over until the end of the season.Undoubtedly, they are two people who live and breathe Man United, and talkSPORT understands the decision is imminent between the two.But even if they do well from now until the end of the campaign, this feels like a club that is trapped in a never-ending loop of trying a manager not connected to the club, then just turning to a former player when it goes wrong.It hasn’t worked so far and doesn’t seem like a recipe for success.
