And time is of the essence when it comes to bringing a new man in.
A handful of different names have been linked with the job in one way or another - some big names, some a little more nuanced. There are names from home and abroad, some with Championship experience and some less so. As the picture becomes clearer, it’ll be fascinating to see where the Owls go with it.
We asked you, the Sheffield Wednesday fan base, who you fancied in as the next boss and you replied in your droves.
Here are a few of the names you told us you’d like to see replace Moore.
17. Giuseppe Iachini - 6/4
The new favourite following reports of his interest in the role over the weekend. Having jumped into management in 2001 in controversial circumstances - he did not have his requisite coaching license to manage Serie A Vicenza so was officially listed as ‘Director of Football’ - and has held 17 roles in the top twi divisions of Italian football since.

Another manager who has been heavily linked with Wednesday in years gone by is Chris Hughton, currently head coach of Ghana after a difficult time of it with Nottingham Forest. Out of club management for over two years, he has Championship success on his CV. Photo: Tony Marshall
20. Slaven Bilic
One of the recent revellers of the Watford managerial conveyor belt, the Croatian enjoys the cut and thrust of the Championship and has success to match. He’s another that wouldn’t come cheap but is looking for work. Photo: Clive Brunskill/Getty Images
