true.
well, we can now say "We know Sastre worked with Riis at one point, at least"
jokes aside, you're right of course, Sastre is an interesting case and has done remarkably well to keep his name out of the gossips.
What makes Sastre so puzzling, IMO, is that we largely know who was taking care of the doping at his teams, and yet his name has never popped up anywhere. He wasn't in Puerto as far as we know, which would be a likely way to get caught for a CSC rider (after being paged to Fuentes by Cecchini or Riis; but he's never been linked to Cecchini either).
About the only high-profile name I can think of is Terrados, who was ONCE's doctor when Sastre turned pro with them in 1998. But as far as I know, there's never been any indication that Terrados freelanced later on.
Sastre strikes me as the kind of guy who would stick to the logistical minimum* (EPO/blood bags, testosterone, and little else), going by previous experience of what he felt worked for him rather than by whatever the latest doping theories said. If that's the case, perhaps he didn't
need to have a doping doctor after literal time-wide doping became a thing of the past. But still, that would work for EPO, but presumably not for transfusions. It's hard to imagine the Carlos Sastre from
Overcoming dealing with anything more complicated than a syringe or some pills.
*Just to be clear, I don't mean he'd necessarily be getting only a minor boost, just that he'd want to keep things simple.
