Roche forced his preparations upon his injuries in the spring, and that is why he couldn´t perform as expected in the Giro, there wasn´t enough time. I would expect him to be in absolutely perfect condition when the tour starts, like the rest of the bunch, and if this goes down to be a battle of the best team, I have no doubt whatsoever that Tinkoff will win the battle, and with a big margin.
I have no illusions that AC should be able to follow Froome in the TT, the only way he can win is by dropping Froome, and I think he will be able to in the 3rd week. It will be a long and hard battle in every aspect, but with the best team and the best fighter and the best tactician in the car behind, I´m confident they can pull it off.
