Ferguson has taken issue with Hansen's comments about his team this season.
It is believed club officials have contacted the BBC to point out Hansen's offending words, including the phrase: "By their own standards, United have been woeful for the past 18 months. I can't recall Sir Alex Ferguson's team being so bad for two successive seasons."
And Ferguson himself followed up on Friday morning.
"He tried to change it [what he said] by saying it was about our away form," said the United boss.
"I have read the transcript of what he said and he said we were woeful for the last year and a half. He didn't mention away games.
"He's dug himself a grave really."
Ferguson is convinced Hansen made his comments in a direct attempt to rile United ahead of last week's FA Cup tie with Liverpool at Anfield last weekend.
And he is adamant the facts do not bear out Hansen's words.
"He's got a responsible position in the role he has in football," said Ferguson.
"That's no problem with me.
"He's maybe tried to shake things up a bit but he should be more responsible really.
"When you think about it we won the league by nine points last season, made it to a European final and were in the FA Cup semi-final - we couldn't have been that woeful."
