He's Spanish
Has a big nose.
Doesn't speak English.
Didn't discover weightloss before winning today.
Didn't suffer a disease before winning today.
Isn't Australian or British, nor does he ride for BMC, Garmin, Sky or HCT - all of whom are completely and utterly anti-doping teams and who would never ever, ever think about doping. None of their performances are ever suspicious so when someone beats them it must be because they are on drugs.
His dodgy DS is an Italian dodgy DS, which is different to those riders with dodgy German, Belgian, Danish or British DSs.
Clean riders normally have a chin that looks like an ****, or have ripped of their looks from ageing rockers, or look like an extra from Lord of the Rings.
Also, the new level playing field thanks to the biopassport means that the likes of Wiggins, Froome, Evans and Cavendish are able to compete and win clean, hence and therefore, when these clean riders are being beaten it must be because the riders who are winning are doped.
