For Bjarne Riis and Oleg Tinkov the past is never a different country but always present. Frenemies who have the sharps to build something good in cycling but who seem to spend much of their time tearing it down.
We know them well. Riis won the 1996 Tour de France as "Mr. 60 percent", doped up to the eyeballs as he made a mockery of the sport on the road. Tinkov doing the same but for different reasons - team owner more interested in being the centre of attention and a bigger star than the riders he employed.
Our dynamic duo, one a usually taciturn Dane, the other a bombastic oligarchic Russian capitalist, has spent the past week or so throwing punches at each other over the now defunct Tinkoff (formerly Tinkoff-Saxo), in which they both once had a legacy.
"Many times I have asked myself about what happened. I have no answer, and it no longer means anything to me. I have long since moved on," Riis told Ekstra Bladet in an interview (translated by Cyclingnews) showing that he hadn't really moved on.
Riis suggested that Tinkov was filled with envy over the respect he is usually given by many within the sport despite his doping past.
"I think it was envy," he said. "I enjoyed the respect of the riders and the other employees. Respect is something you have to deserve. It's something you build up over years. It is not something you buy."
Of course, there was no way Tinkov was going to let that one go. In typical style, Tinkov shot back.
"I guess it is hard to understand the nature of capitalism, growing up in socialistic Denmark," he told Cyclingnews.
"I never said that before, but if he opens up the discussion, I should say that people like Riis, (Johan) Bruyneel and (Jonathan) Vaughters must be banned out of cycling for life.
"They not only highly promoted doping but also materially benefit from it. I see this as a crime, actually. Pity that such a people are getting back into my sport."
Professional wrestling has nothing on these two. Sadly, both are likely to be back running WorldTour teams sometime in the future and judging on career form, probably in partnership. They deserve each other.
