The former Manchester United manager is in the hot seat again, appearing as a guest contestant on the last live edition of ITV's quiz programme Who Wants To Be A Millionaire? tomorrow.
But instead of inviting his former players, whom he criticised in his autobiography, Sir Alex will team up with United supporter and This Morning presenter Eamonn Holmes.
Holmes will appear alongside the Scot, who is a student of the American civil war. The pair will appear in the celebrity edition nine years after they first took part in the show together.
Holmes won £32,000 last time with Sir Alex, who was given the BBC Sports Personality of the Year's Lifetime Achievement award at the weekend.
The presenter said: "It will be a chance to see if Sir Alex still possesses his winning ways and if we can get the better of Chris Tarrant with our mind games. Although it's a tremendous honour to be invited back, the pressure is on to see if we can better our winnings."
