I don't see what's so wrong with bringing out a book in Spanish of his life so people in Spain know Cristiano more?? as alot of people in Spain can't speak English so wouldn't of understood his previous book, plus it will probably be updated to include his "dream" of joining Real Madrid. Besides, it's Cristiano's success/story too, not just "United's success" he was the main part of that team been so successful so he has a right to tell his story and make money off of it like all players do.
If you don't want to read it don't buy it, but you don't need to ruin it for everyone else. Not everything is so cynical you get what I mean?? how about reading the book first before judging it?? plus theres going to be alot of books about other players too, not just Cristiano, it's a series of books by the journalist.
The people who want to buy it will find the money to buy it (like everything they buy), and the people who don't won't, it's a simple as that, I'm sure Cristiano doesn't mind, but I will buy Cristiano's book as I try to support him as much as possible (not that people who don't buy his book don't support him, they probably can't afford it, or have a genuine reason they don't want to buy it etc, it's up to the person which I'm sure Cristiano respects).
