Genuine question, have you even read the book?
I have and it's not a big juicy kiss and tell like the media would have you believe, also all players were asked about being in the book, and the book is for charity so of course some benefit has come from it, but if you haven't read it already then I recommend it as a good read!
I have read similar books with the last being AVBs they are all much of muchness. I just object the principle of them, no good ever comes from them and it is often a sign of manager buying into their own hype. It may not been a huge kiss and tell but small aspects like disclosing Ali is learning Spanish demonstrates real naivety on his part.The charity aspect is admirable but I think there was a far better means of achieving that.
