A customer has been refunded the cost of purchasing Sir Alex Ferguson's autobiography after complaining about the number of factual errors in the book.

The reader is said to have spotted up to 45 mistakes in the memoirs of the former Manchester United manager.

The Mirror quotes publishers Hodder and Stoughton as writing to the customer in an email: "We did in fact go through several stages of fact-checking with this book, with a reading from within Manchester United as well as from a specialist football fact-checker.

"Although a very large number of corrections were made, we plainly did not pick up everything.

"I am sorry that you feel that your expenditure on the book was not worthwhile. If you would like to send the book to me at our head office address, stating where you bought the book and at what price, we will refund your expenditure and postage."

In the book, Ferguson says that the procedure to fit his pacemaker took place in April 2002, when the actual date was March 2004.

It is also claimed that Ryan Giggs made his debut for the club aged 16, when he was actually 17 at the time of his first appearance.
