Birmingham City chief Tom Wagner admits they should not have sacked John Eustace.
The head coach had the club in the upper half of the Championship table when he lost his job.
Wayne Rooney was appointed to take his place, who did not last more than 83 days in charge.
“We made one decision that if we were to go back in time we wouldn't have made," said Wagner, per The Mail.
“I don't think we can ever ensure every decision we make will be a perfect one.
“There were some good lessons learned with some of the decisions we've made this year and there have been substantial learnings about how we think about making important decisions on the sporting side.
“In the context of having made thousands of decisions foe the club this season, we made one that wasn't perfect."
