Robinson, now coach of Edinburgh, left his position last November after a run of eight defeats in nine games.

"One of the things that upset me more than anything was the way that I was routinely portrayed as a bad coach," Robinson told the Guardian.

"I'm not a bad coach. A lot of people made comments which were out of order. They don't know me. They haven't seen me working with players.

"They made judgments which ignored the context of my position with England and the difficulties we faced."

Robinson had been in charge since World Cup-winning coach Sir Clive Woodward stepped down in 2004.

Problems continued after he left with England struggling in the early stages of this years World Cup before rallying to reach the final.

The Rugby Football Union are now undertaking a structural review which could lead to changes Robinson would have liked to have seen himself.

"I wanted a manager to work alongside me but I was too dumb to insist upon it," Robinson said.

"The plan we tried to put in place for England in 2004 will finally emerge in 2008. The guys in charge next year will basically get exactly what I wanted.

"It's great for them and for England rugby because, finally, the international team can move forward. But, yeah, it's frustrating for me."
