Paul Dickov has described the pain of relegation as the “biggest let down” of his career.
However, the Scot is determined not to look back in anger and says he will be a better manager for the experience.
Dickov is busy throwing himself into preparations for Rovers’ latest assault on League One.
He was scheduled to meet with the board on Friday to discuss potential transfer targets as he plots a quick return to the Championship.
But Doncaster’s dramatic final day demotion - and the agonising stoppage time circumstances in which it came about - have left Rovers’ boss still trying to come to terms with a low-point in his 24-year career in the senior game.
As a player, Dickov was part of the Manchester City squad relegated to the third tier for the first time in the club’s history in 1998.
But the former Scotland international, who is now determined to forge a successful career as a manager, ranks his disappointment at Doncaster as even harder to swallow.
“It’s the worst [moment of my career],” said Dickov.
“If I’d managed to keep the club up it would’ve been the biggest achievement of my career.
“Now it’s the biggest let down I’ve ever had.”
Given Doncaster’s relative lack of spending power in the Championship, keeping the club in the second tier would have considerably raised Dickov’s stock in the game, following his previous spell in charge of League One Oldham Atheltic.
But Rovers’ boss is determined not to dwell on relegation, and has vowed to only look forward rather than back.
He said: “We can reflect and go back over loads of things that have happened.
“But I’m a big one for no regrets.
“We have to look forward now. Otherwise you’ll send yourself absolutely mad looking back at what could have been.
“I’ll be a better manager for what’s happened over the course of the last year.”
