Former Manchester United manager Sir Alex Ferguson is planning to launch a new book focused on leadership.

The 73-year-old, who released his second autobiography in 2013, has joined together with author Sir Michael Moritz to detail the "key philosophies" used in his 38 years of football management.

"The process behind creating this book began many years ago following my first meeting with Mike, which immediately created a mutual respect for each other's achievements," the Daily Mail quotes Ferguson as saying.

"Over the past year, we have spent many hours together as we have worked our way through my life in order to draw out and discuss the key philosophies I applied during my career."

The book, which is titled Leading, will be released in autumn.
