Former Manchester United manager Sir Alex Ferguson has reportedly been forced to move his press conference in London due to a royal family event.

The Scotsman was due to speak to the media ahead of the release of his second autobiography at the Institute of Directors in Pall Mall on October 23.

However, due to the christening of Prince George at St James's Palace, Ferguson's event has been moved to the day before, according to the Daily Mail.

Ferguson's autobiography is being released following his decision to retire as United manager after 26 years at Old Trafford.
