Astana should have been kicked off the World Tour but other teams are just as bad. How about Tinkoff-Saxo, formerly owned and run by Bjarne Riis? The Danish Anti-Doping Agency made more serious allegations recently.
Steven De Jongh, key member of Sky's managerial team, confessed to doping in 2012. After leaving Sky, he joined Tinkoff-Saxo.
Btw, do you think that Sky, who employed Dr Geert Lenders (life ban for doping riders) in 2012, is a clean team?
