I think it would be a good idea, that way we'll know any news we get is 'official' because we'll hear from the man himself.
but do you genuinely think he would update a site with news himself?!
i mean look how private the guy is
he doesnt talk about his love life, his family life (rarely!) and hes dodgy with his football life
theres only so many questions you can ask him about football before he starts repeating himself
not to mention, he wont be able to properly explain situations about his tranfer situations
it would be good for him to have an official site
but this one, and the pt.vu site are the best sites youre gonna find on him
but the pt.vu is more concise, but even those people who run that site and know cristianos family themselves are picky about what information they choose to publicise and what information they choose to withhold
