"It is recognised the world over, so why would the family even consider a change?"
And to suggest the position of Sir Alex, who will complete 19 years in the job in November, would come under scrutiny has horrified the Glazers.
The source said: "The Glazers are determined to ensure continuity and success prevails at Manchester United and Sir Alex is a key player in those plans. Suggestions that his position is under threat are way off the mark.
"Sir Alex has a future at the club for as long as wishes."
As for Sir Bobby Charlton, the source added: "Those particular claims have horrified the family, who hold Sir Bobby in the highest esteem possible.
"In all likelihood he will have a more active role because the family recognise that Sir Bobby is a historical and respected figure at Manchester United the world over.
"As far as the Glazers are concerned, like Sir Alex, Sir Bobby has a guarantee of life employment by the club's new owners."
