Iain Dowie insists he is not bitter about his sacking by Charlton but says he is upset by reports about his six-month reign at The Valley.
He was dismissed as manager in November after only 12 league games.
Dowie told BBC Five Live Sport: "It's history. It's a good club and the fans were very good to me. I've moved on.
"What's disappointing is what has been said and what's been spun out of it - the lies that have been reportedly told about my tenure there."
Dowie presided over two Premiership wins during his brief reign but since his departure, the Addicks have managed only two more victories and his replacement Les Reed has left the club.
Charlton also crashed out of the Carling Cup at the hands of Wycombe in December and on Saturday were beaten in the FA Cup by Nottingham Forest.
However, Dowie said he hoped the club - now managed by Alan Pardew - would win their battle against relegation.
"I worked as hard as I can and did it with a certain dignity - I'm not sure everyone can be the same"
"I believe we had a good enough squad to stay in the Premiership and I hope they stay up," he said.
"What sticks out for me is people like the laundry lady had tears in her eyes when I left the club so that must mean I had some good impact on the people that matter.
"I can look back and know I worked as hard as I can and did it with a certain dignity - I'm not sure everyone can be the same as that."
Dowie, who left Crystal Palace in May 2006 to replace Alan Curbishley at Charlton, wants to return to management as soon as possible.
"I've done a lot of things right in my career," he added.
"Character is not about when everything's going well, it's about when things don't go so well. It's about how you respond to it.
"I've never been one to quit. I'll get back on the horse and ride as soon as I can."
