Coventry City CEO Tim Fisher has said that Andy Thorn was sacked for not being able to get the best out of his players.
Speaking to the CT's Andy Turner and Alan Poole, Mr Fisher said: “Let me be very clear, this was a football decision, not some dark-side innuendo or whatever.
"Andy has gone because he failed on the football side.
“To me the second half against Bury, abjectly losing two points from a position of strength, was a symptom of an underlying problem that we had aimed to correct during the summer and that progression hadn’t happened.
“It was another data point suggesting we’d gone from a pattern to a deep-set trend.
"And we had to break that trend – insanity, as defined by Einstein, is to do the same thing over and over again and expect a different result.
“We employ a manager, a head coach, whatever you want to call him, who puts out the players who he thinks are in the right state of mind, the right state of fitness.
“At the end of last season we sat down and Andy made a presentation along the lines of ‘if I get what I want then this will change.’
“He told us that he needed Richard Shaw and thought we should bring Lee Carsley up. He gave us a list of players which Steve Waggott delivered.
“You’ve changed nine resources – not one, not two, not seven but nine – and you get the same result! You’re given all the tools and we don’t see any change.
“With a trend you’ve got to extrapolate. We did that and we felt as a management team, as a board and as an owner that we didn’t have the confidence Andy would be able to take on all the resources that he had chosen and be able to actually get it over the line.
“You’ve got the tip of the iceberg which is the 90 minutes on the pitch – the rest of the iceberg is Ryton, all the practices, all the training that is going on there, all the discussions between manager, development director, assistant managers.
