My 10yo DS dreams of being a football manager, and I'd like to get him a book for Christmas that will fuel his interest. I can see a few on Amazon, ranging from tactical guides to autobiographies. I don't have a preference for the type of book - I just want it to be an inspirational read, and suitable for a 10yo. It doesn't have to be specifically aimed at children, but I don't want one that contains colourful language or anecdotes about the steamier side of life as a football manager.
Any suggestions?
