Say what you want about the strength of United's squad at the current time, but no one can argue that this wasn't always going to be a period of unprecedented transition.
There has been an abundance of theories banded around the web about which recognised star Moyes should bring in to ease his apparent teething woes at Old Trafford.
For me though, the ideal signing isn't necessarily a marquee one on par with the likes of Cesc Fabregas and Andres Iniesta, but rather an industrial midfielder who has the experience and class to ease the obvious issue currently confronting the Premier League champions.
Firstly, a proper introduction is in order. Daniele de Rossi; the long-serving Roma midfielder who has 93 caps for Italy, scored a penalty to help his team lift the World Cup in 2006 and is adept in both central defence and midfield.
For Moyes, attempting to sign the 30-year-old should be a no brainer.
With De Rossi they would not only be bringing in a player who has an exceptional level of high-level experience in crucial fixtures, but also a man who has proven himself to be capable in multiple areas of the game.
The Fellaini transfer will more than likely come good given time, but for now United must focus on making it through the rest of what has so far been nothing short of a disastrous season, without suffering anymore major hiccups. Following that the next port of call is ensuring that they give themselves the best possible chance of starting strongly next year.
The big Belgian will take a while to adapt to life at one of the biggest clubs in the world, and the Red Devils' faithful may have to wait a while for the fruits of his transfer to be readily evident.
Rather than taking more gambles on figures such as Lars Bender and Yohan Cabaye, Moyes can be offered a certified breadwinner in De Rossi, and one who will more often than not be more than a match for his opposite number.
His versatility should be a key factor too. The loyal Roma servant has spent the majority of his career flitting between centre midfield and centre-back, and has been utilised to great effect in both roles at major tournaments with Italy. In midfield he could partner Michael Carrick, being able to cover defensively and tuck in when his team are under pressure, but also possessing the attributes to be effective when going forward.
Alternatively as a centre-back De Rossi would be more than able to cover for either Nemanja Vidic or Rio Ferdinand, and as opposed to spending big money on players such as Eliaquim Mangala or Ezequiel Garay- individuals who could quite easily suffer from 'weak league syndrome'- De Rossi can cope comfortably at the top.
And it's his overwhelming experience that leads nicely into my next point.
When United lost Paul Scholes they lost a nailed on asset who could be relied upon to inspire when the going was tough, and do the maximum amount of damage when given the time and space to flourish. De Rossi is similar in this respect.
Whilst maybe not possessing the same accuracy over the long ball as Scholes did, De Rossi is a tenacious tackler and has the mental strength to ensure that things don't fall apart when others give up the ghost.
For me De Rossi is the embodiment of everything Moyes' United have been bereft of since this the first ball was kicked this season.
His defensive nature is complimented by his natural ability to surge forward and the fact that he is 30 means that he'll probably be available for a cut price.
His age may also play into United's hands when it's considered that this is potentially the last time an offer of such prestige may come De Rossi's way. He's been courted by Real Madrid and Chelsea in the past, but always acted with unerring loyalty to his parent club.
Sure, he's not the long-term fix, but he's definitely the ideal candidate to plug the current hole that has opened since Ferguson's retirement.
