Publishers of Sir Alex Ferguson's autobiography have agreed to refund a customer after multiple inaccuracies were found in the book.

According to the Mirror, the former Manchester United manager’s second account of his life, entitled My Autobiography, became the UK's fastest-selling non-fiction book since records began, shifting 115,547 copies in its first week on sale. However, eagle-eyed readers have spotted as many as 45 factual errors in the 402-page account, which has prompted publishers Hodder and Stoughton to offer to reimburse one disgruntled customer, the report said.

Hodder and Stoughton CEO Jamie Hodder-Williams is said to have replied by email to the customer in question, offering a full refund in exchange for the return of Ferguson's autobiography, the report added.

Among the inaccuracies in Ferguson's account of the latter half of his 26-year Old Trafford reign are his claim United had 11 years out of former captain Roy Keane, when it was actually 12, the report further said.
