Since returning to Chelsea, Jose Mourinho's leadership has been far from convincing and he has not managed to get a grip on what his best team really is.
Quite simply, the so-called Special One has not got it right, and there are many reasons for this.
Typically, with Mourinho returning to the club as a hero, Chelsea supporters believed that it was going to just work out as it did initially in his first spell, but that is not going to be the case.
The fans thought that success would suddenly follow for Mourinho at Stamford Bridge, but that is not always the way that football works.
I have seen many big names return to their 'spiritual home' in football, to where they were previously loved, and it never lives up to the expectation of how it was before.
Mourinho must learn that he must change, because football is changing around him and it has done significantly since his last spell at the club.
The top players at Chelsea will not be happy to just sit around in a world of Mourinho harmony, particularly with the World Cup to follow at the end of the season.
The likes of Juan Mata and David Luiz will not be content being constantly brought on as substitutes or rotated because they want and need to be playing.
It must be incredibly frustrating for some of the other players to see how John Terry has basked in his manager's favour because he is an old favourite of Mourinho's and not everyone will be seeing the new boss as a breath of fresh air.
Mourinho signs a lot of players purely for the sake of other clubs not being able to have them and you look at the Chelsea squad and wonder how many of the players are rated by him.
He is a manager who has his 'own players' and does not appear to be open-minded to others that do not fit into his tried and tested way of doing things. Mata has been a real victim of this way of blinkered thinking.
While the likes of Terry are getting on Mourinho's good side, other players are not prepared to be bossed around. It just doesn't work that way.
Under Rafael Benitez, Chelsea ended last season as the best team in the league playing fantastic football.
It looks as though Mourinho is trying his best to dismantle all of that because of he is still bearing a grudge against Benitez. That might be the real problem.
What is Samuel Eto'o doing at Chelsea? Why would he be brought in when Romelu Lukaku was already there? It is absolutely ridiculous.
If Lukaku continues his fine early form at Everton then that call could come back to really bite Mourinho, because he should not have let the powerful forward go.
As for Moyes, it is the United players who must shoulder the blame for their poor start to the campaign because they have not been performing at an adequate level.
A lot of the players at the club are in a crisis because they have never known what it is like to be at Old Trafford without being under the leadership and guidance of Sir Alex Ferguson.
The experienced players are the ones who must step up and deliver, such as Rio Ferdinand, who simply has to do better than he currently is.
Questions can be asked of the likes of Phil Jones and Ashley Young as they struggle to establish themselves as top players at such a big club, while consistency has been sorely lacking across the team.
Moyes needs to see these fringe players moving up a level because they have been at the club for a while and have to start making a real impact if they are to stay at a club like United.
Equally, he should not have made such sweeping changes to his backroom staff because Phil Neville, for example, does not have adequate experience to be working at such a big club right now.
He may know the club, but he does not know the current players well enough to provide Moyes with the support he so desperately requires with many not seeming to be motivated enough.
Some of the players need a kick up the backside, but it is very difficult for Moyes now that he does not have staff surrounding him who have been at the club a while and who know everyone very well.
But Moyes should not be under pressure so early in the season and he has enough experience in football to see him through what has been a testing start to his career at United.
