Don't know what he is doing. I thought after the Coppi he can go to Dwars door and De Ronde, maybe Roubaix, amstel, Liege. He had decent legs and Astana sponsors could have done with him at those races.
If he's doing the Giro, he needs an altitude camp. So if he races Sicilia, that means no Liege if he wants to be in the best condition for Giro. Alternatively, he does the ardennes after Sicilia and the Giro is a parade for him.
Astana is a total shambles right now without Lutsenko. Superman comes back for Trentino in 2 weeks and they need him desperately. I don't understand the Vicnenzo participation at the Giro. If he wants a parade, he can do it next year (already last year he did it).
Or come back from altitude for Liege and skip Sicilia
After doing some digging since Astana seems to be very secretive with their training camps, found a random Spanish photographer who posted on instagram a picture with Nibali, Feline and another Astana rider on the roads on Teide five days ago. So altitude is checked.
As we all know the long stop caused by illnesses messed up all his programme so the only reasonable goal remains the Giro for now. Sicily is a good idea, low profile, familiar roads, Etna stage with the same finish as in the Giro. I think he will ride LBL like every year.
