Terry Venables believes he should have been allowed to "finish the job" at Leeds and keep the club in the Premiership.
Venables has little good to say about chairman Ridsdale
The former Leeds boss has also admitted that he was sacked by the club and that his departure was not by mutual agreement, as was first announced.
Venables left his post as Leeds manager on Friday and was replaced by former Sunderland boss Peter Reid, who will manage the club until the end of the season.
Peter Ridsdale feels he has a reason to let me go. But I also have my opinion about his behaviour this season
Writing in his weekly column for Sunday newspaper News of the World, Venables also made a thinly-veiled attack on Leeds chairman Peter Ridsdale, admitting they had a difficult relationship.
"I'm not bitter. I'm angry because I don't think the directors see the situation correctly," said Venables.
"I did not quit Leeds United, I was sacked.
"Peter Ridsdale feels he has a reason to let me go. But I also have my opinion about his behaviour this season.
"And I think he has got this wrong. The directors should have given me the chance to finish the job."
Unsurprisingly, Venables writes that the departure of international stars Robbie Keane, Lee Bowyer, Olivier Dacourt, Robbie Fowler and Jonathan Woodgate left his side in tatters.
The sales, along with that of Rio Ferdinand at the start of the season for £30m, were completed because of Leeds' perilous financial position, something Venables claims not to have been informed of when he took the job.
He remains particularly disappointed at the departure of Woodgate, after it was announced that the defender did not need leave for financial reasons.
"I find it hard to believe that the club didn't know the extent of the financial position when I took the job - not when it turned out to
be so bad," he said.
"Losing Woodgate was the killer - a massive blow. To then hear it didn't need to be done seemed to show no sensitivity to the football end of the business.
"We really needed him. Central defence has been a problem for us all season because of injuries and with him there we could have coped.
The manager and the chairman need a trusting relationship and we had problems in that area
"As the squad grew weaker we had to fight harder and harder. Then the chairman says the results aren't good enough as if the two things (selling the club's best players and losing matches) are unrelated."
Venables has no doubts that his position was not aided by the behaviour of the board, especially Ridsdale.
"The manager and the chairman need a trusting relationship and we had problems in that area," he said.
"The board sold players I didn't think should be sold. OK, that is their right. But having taken the decision I think they should then take their share of the responsibility for the problems the team had as a result.
"I look back on my time at Elland Road with no regrets. I conducted myself properly. Whether the board did the same is for others to judge."
