Ron Atkinson was sacked as manager of Manchester United on November 6, 1986 after an abysmal showing in the league.
A League cup exit at the hands of Southampton was all that was needed for Atkinson to get the boot.
Ferguson has accomplished what no other manager has; he has kept United at the pinnacle despite being in transition between players, staff and board.
Time and again, from Eric Cantona to Nemanja Vidic, he has made astute dealings which has allowed him to form a blend of youth and experience who have, despite the harshest circumstances, claimed glory.
This slideshow pays homage to this great persona, recounting the 25 years he has been in charge of Manchester United.
