David Meek, who helped write Sir Alex Fergusonâ€™s autobiography and also writes his Old Trafford programme notes, made the suggestion on talkSPORT yesterday.
Meek said: "I canâ€™t honestly say Iâ€™m aware of anything. We never hear anything from the Glazers but theyâ€™re in charge. There is the scenario that he was blissfully intending to carry on for another season, true to his programme notes, but then there was a top summit meeting and the suggestion was made (that he retired). I donâ€™t think it had to be made forcefully. If he felt the owners no longer had 100 per cent confidence in him, I donâ€™t think heâ€™d hesitate [to go].
When pushed if he thought that was realistic, he replied: "Well yeah... Iâ€™d love to know. Thatâ€™s the next chapter to the story. Did he go or was he pushed?"
He added: "I knew something was afoot when I rang him [on Tuesday] at his home and I said â€˜shall I come in tomorrow morning?â€™ He said â€˜no, I shall be too busy.â€™ Thatâ€™s all he said."
