As previously said, Menchov is hardly taking a huge dump all over Cadel in terms of talent, but by targeting the right races and racing sensibly, Menchov has put together three Grand Tour wins. It's quite clear that that duck egg next to his Grand Tour win column is a major monkey on Evans' back, and so he'd be an idiot to put all of his eggs (sorry) in the Tour basket. So he won't. But if he's still going to have half an eye on the Tour because he can't let it go, he'll sabotage his own Giro chances. But then, if he stakes everything on the Giro, even if he wins he may not have enough in the tank for the Tour (Menchov was about 65th overall in 2009!) and, when the team are invited solely on the back of him, that will reflect poorly on the team and perhaps annoy the ASO. It's a difficult balancing act for him to carry off, especially if commentators are (implicitly) suggesting that he could do the double, because even auscyclefan94 knows that's not going to happen.
