Personally I take everything that comes out of either side with a large helping of salt. Main reason? Neither of them speaks English as a first language, GSP's on the record as saying that some of the stuff that comes out in his interviews isn't quite what he meant since he's not quite fluent in the language. Interview him in French and we'll be able to get a much better idea of what he's actually thinking and what he really means.
Anderson's camp, especially Ed Soares have been known to give, how should I put this, less than accurate translations. Until I see a Portugese interview which is translated by a professional I'm going to have a hard time taking it seriously.
