Portuguese rider Sergio Paulinho is changing to Discover Channel next year, although he was one of the riders apparently implicated in the doping affair around Madrid-based doctor Fuentes. But team manager Johan Bruyneel does not think that there is a problem according to Belgian Sporza. "He doesn't have to do anything with the case at all," Bruyneel said. "He has a certificate from the Portuguese federation which clearly states that he has been linked wrongly to the case. In these matters, I don't take any risks."
