Sven-Goran Eriksson says he is saddened by his exit from Leicester City but still believes they will win promotion to the Premier League this season.
The Foxes said the former England manager left his role by mutual consent on Monday with the club just two points off the Championship play-off places.
Eriksson said: "I have always thought, and still believe, that the club will be promoted this season.
"But football is a results industry and we couldn't get things right enough."
The club's big-spending Thai owners are desperate to win promotion to the top flight this season.
And they have been unimpressed with an inconsistent start to the campaign in which they have won five and lost four of their opening 13 league games.
In a statement issued by the League Managers Association, Eriksson said: "It was always my aim to lead the club into the Premier League.
"I am very sorry I won't be able to do that. Being the manager of Leicester was an absolute pleasure."
Eriksson was named Leicester manager in October 2010 and steered them away from the Championship relegation zone and close to a place in the end-of-season play-offs.
And, although City are only two points off the play-offs and just five points off an automatic promotion spot, the decision to replace Eriksson was taken following Saturday's 3-0 defeat at the hands of struggling Millwall.
Eriksson added: "I wish everyone connected with the club the best of luck. Leicester City is a great club and I am certain that, with the current owners in charge, the club will go from strength to strength.
"To the players; old, new, everyone in the squad, I would like to say thank you. You are a talented group and I am hopeful you will achieve success very soon.
"To the staff at the club - both at the stadium and the training ground - you treated me like a king and I shall miss working with you all.
"Last but not least, to the fans; I want to say a huge thank you for your support. You are fantastic people and I will never forget the way you welcomed me into your club. I am just sorry that I won't be on the bench the day you reach the Premier League."
