Stuart Delmonte and Tony Rosenberg cited several grievances behind their decision to stand down as managers of Reich Insurance Blue.
The pair became increasingly disillusioned over the way the league was run and voiced their disappointment in an email sent to clubs and the management committee in December.
But league secretary Paul Rose hit back and said: “The points they made had been addressed in a positive and constructive manner at the last council meeting.
“We received their email in December but, for starters, any emails should come via the club’s secretary.
“In this instance the claims were not a full representation of their club. It was also not backed by any other team.
“There was no reason for us to reply as it received a negative response. All they did was fire bullets in an email.
“All we have ever done is for good of the league. The league has been going for years and while there is a community there will always be a league. Times are changing and we know that, but the league functions.
“We are not in dire straits. In fact, we have received application for a new team joining for next season."
Delmonte and Rosenberg insist they won’t walk away from football management altogether.
Talks have already begun to reform AFC Flixton, who disbanded from the Accountants Premier League last summer, for next season.
But the prospect of a return to Jewish football appears out the question for the double act.
Rosenberg, who along with Delmonte had twice previously been persuaded to stay on, claimed he had reached the end of his tether with the MJSL bosses.
He said: “We wanted to get back to our roots and were excited about our return to Jewish football.
“But in hindsight it was a mistake on our parts. It’s been a pleasurable experience. But we don’t like the politics. The executive committee are so far removed from reality.
“They simply have no idea about the stresses and aggravation of fielding a team, the costs and efforts involved.
“I’ve been involved in football since 1973 in one way or another. It’s a big part of my life and not to be involved is a massive decision and it’s the first time I’ve walked away mid-term and haven't stuck it out. But enough was enough.”
Reich Insurance Blue are now on the lookout for a new manager.
Director of football Michael Gastwirth and club secretary Ben Burton will lead the search.
Gastwirth, who runs the title-chasing White team, said: “We will look to implement as short-team player manager and we’re in discussions with several candidates.
“There will be no conflict of interest. We will hope to have a successful season with Reich Whites winning the league and Reich Blue winning the Shonn Trophy.”
