David Moyes' record as Manchester United manager makes for poor reading. Having won six, drawn three and lost five of his 14 games as Manchester United manager, it's clear that this Scot will never fill the hole left by his predecessor.
Ferguson had been ingrained in the fabric of the club since 1986, and replacing such a key part of United's structure will inevitably cause disruption - but unless Moyes can correct his attitude quickly, fans may start losing their patience with the former Everton boss.
In his interviews and press conferences, Moyes gave the over-awed impression of a prize winner, or a fan at the helm of the club he supports.
He fawned over the facilities, the work rate of the players and the position he has been given. He sounded like a naive young bride - his head full of dreams of happiness and success, but without any idea how to go about achieving them.
Comparing David Moyes to Sir Alex Ferguson at this stage in his career is like watching a Beatles cover band; sure, they might play the same songs - occasionally as well as the originals - but they'll never write another 'Abbey Road' or 'Hey Jude'.
Rather than mould a team in his own style, Moyes has tried to continue where Ferguson left off. The best Moyes can hope for at United is to reach Ferguson's lofty standards - but out of his comfort zone and over-awed by the greatness that came before him, Moyes' lack of boldness could see him remembered as the United boss that turned them from European challengers to top four also-rans.
Moyes' management of his squad has raised some eyebrows among United supporters and onlookers alike - the treatment of Shinji Kagawa perhaps most baffling of all.
At his best one of Europe's top playmakers, Kagawa has been farmed out wide for United and overlooked for the likes of Tom Cleverley and Ashley Young in Moyes' starting lineups. Clearly, Moyes does not know how best to use a player of Kagawa's kind.
In his Everton days, Moyes has never had a player like Kagawa. - preferring instead to opt for a workmanlike midfield of Leon Osman, Marouane Fellaini and Phil Neville.
Indeed, the emergence of young Ross Barkley under Roberto Martinez has shown that Moyes does not value the kind of technical midfielders that characterise many of Europe's top sides.
Moyes has come under further criticism for his dealings in the transfer market this summer. The signing of Fellaini amidst the vocal and public courting of Cesc Fabregas and Thiago Alcantara proves how much Moyes has to learn about dealing in the market's upper echelons.
The huge influence of player agents, club chairmen and the media in the summer window is something Moyes will not have faced before, and after making ill-advised overtures to Fabregas and Alcantara - along with a botched move for Ander Herrera - going back to the tried and trusted Fellaini shows a manager bereft of ideas and without the experience to attract Europe's top talent.
So far this season, Manchester United have managed just a single point and two goals against the Premier League's top teams. City and Liverpool both beat United in the league, and if Mourinho had been a little more adventurous, you feel he could have taken his chances against a poor United side.
Everton also had an awful record under David Moyes against the league's best teams - winning none of 43 games away from home against Liverpool, Chelsea, Manchester United and Arsenal. This surely proves that when it comes to the big occasions, Moyes is completely and utterly lost.
Manchester United fans would be delusional to expect Moyes to live up to Sir Alex's high standards. Success under Ferguson was so consistent and natural to the club, but now there's a sea change.
Without one of the world's best ever managers, United fans may now start to feel what supporting another club is like.
