Andreu doubts Lance confession
Betsy Andreu, who testified against Lance Armstrong, feels the American will only confess to doping during his cycling career if it suits him.
A recent report in the New York Times suggested Armstrong was considering admitting to using performance-enhancing drugs and blood transfusions during his career so doping officials would reduce his ban, allowing him to then take part in triathlons and running races.
Andreu - whose husband Frankie rode alongside the Texan for the US Postal Team - feels that any admission would have to include naming all those involved.
"Anything Lance does is to benefit Lance and Lance alone," she told Sky Sports. "He doesn't do anything without weighing the benefits to himself.
"If Lance were to confess, and I think that's just a huge hypothetical, he would have to tell everything about everybody, about how he was able to get away with it and the people involved.
"That would mean talking about so many people that he would be the only man standing in a room left without anybody, anybody at all. I don't think it's within him to do that."
Both Betsy and Frankie Andreu testified against Armstrong, who won the Tour de France in seven consecutive years from 1999 to 2005, as part of the 1,000-page report from the United States Anti-Doping Agency (USADA).
The dossier was later sanctioned by the International Cycling Union (ICU), who effectively erased the cyclist from the sport's history by stripping him of his titles.
