Todd has left the Arena after just nine league games in charge
Colin Todd has left his post as manager of League Two strugglers Darlington after four months in charge.
The Quakers have only collected two points this season including Saturday's 1-1 draw at Grimsby, Todd's last game.
He told BBC Tees: "It was agreed before today's game that if we didn't get the win then I'd be leaving.
"At certain levels you're dictated by results, the time factor sometimes isn't long enough but you have to take the rough with the smooth."
He added: "I think the chairman should have been here to address the situation. I've had the players all in together and nobody had any idea, not even my staff [that I was going]."
When asked who had suggested he should leave if Darlington failed to win, Todd added: "It was the chairman. It was [a feeling of] disappointment. It was always going to be a difficult job here and a long job."
But Quakers' managing director Graham Fordy said that Todd's departure had been a mutual agreement.
"He met the chairman on Monday and agreed if a victory didn't come his way on Saturday that he would resign and that's exactly what he's done," he said.
Todd, who is the seventh Football League manager to lose his job this season, believes that the next boss will be brought in from outside the club.
"I know for a fact it will be somebody new," he said. "[Dean] Windass will not get the job so they're looking for someone, I don't know what type of manager," he added.
The ex-Middlesbrough, Bradford, Bolton, Derby and Swindon boss was handed the manager's job at the Arena by returning chairman George Houghton in May.
Before his appointment he had been coaching in Denmark with Randers.
Todd took over at Darlington after former boss Dave Penney left to take charge at League One Oldham.
The Quakers were forced to assemble a new side during the summer after most of last year's squad left.
Raj Singh, who has since taken over as Quakers chairman, said it was regrettable that the club had parted company with Todd.
"Colin is keen to do what's right for the club and accepts the time is right for him to step aside," he told the club's website.
