Nadal has been (perhaps allowed himself to be) overmanaged by the PR machine. He is just an insecure, uneducated kid.
He might pull an Agassi later in his life: kicks Toni off his life, leaves his GF, shaves his head and returns to the tour and wins a few matches, takes some writing classes and writes another book on his own.
