The Red Devils ended Moyes' 10 month stint as United boss today, meaning they are still looking for the man to continue Sir Alex Ferguson's prolonged success at the club after the failure of former Everton boss in his difficult yet brief spell in charge.
Many of the same names suggested back in May are resurfacing again, including Borussia Dortmund's Jurgen Klopp and Bayern Munich's Pep Guardiola, and the bookmakers are already trying to predict who will be installed as the next manager at Old Trafford.
With that in mind, who are the current movers and shakers in the betting markets?
The shock of the market right now is that Chelsea boss Jose Mourinho continues to see his odds shortened. The former Inter Milan and Real Madrid manager had long been tipped to replace Ferguson at United, but it would be a huge surprise to see him leave Stamford Bridge to take over a rival. However, odds as short as 14/1 are now being offered on Mourinho moving to United, making him joint-fourth favourite to replace Moyes.
Also seeing their odds shortened are former Chelsea boss Carlo Ancelotti, currently with Real Madrid, who is currently available at 16/1, and Paris Saint-Germain's Laurent Blanc, who played for United for two years in the early 200's. Blanc is also available at as short as 14/1, but he's widely expected to remain with PSG.
As aforementioned, Dortmund's Jurgen Klopp is again being linked with the post but after recently saying he is 'still in love' with the club, it seems incredibly unlikely that he will be the next United boss, and the bookmakers agree, moving him out to as far as 12/1 despite starting the day as a hot favourite.
Interim manager. Ryan Giggs is also seeing his odds lengthen as it seems United will go for another totally new face rather than promote from within, and the Welshman is currently available for around 14/1.
The hot favourite continues to be Holland national team manager Louis van Gaal. The Dutchman has an impressive CV having managed the likes of Ajax, Barcelona and Bayern Munich to great success, and now odds-on favourite to take the position despite interest from Spurs.
At 62, van Gaal is experienced and has recently spoke of his desire to manage a contender in England, making United a natural fit for him.
