No way, Kiserlovski is far worse, he managed top ten in Giro ONLY because of escape where he took lot of minutes. Last year he was poor, this year better but 11th overall in Basque Tour is nothing showing that he could do well in GC. Kessiakoff is maybe better, but too fragile as you say and that's something you don't need on GT. And this year totally lost until now. So Roman is the best of Astana.
Today he told us something about if his TT ability got worse...doesn't looked like that at all

And he isn't in top shape although. Rides different way than he used to, attacking, active...signs of good form. If Romandie has only one reasonable climb, he could do better that sixth overall. Today he said he felt good, same as yesterday, getting better day by day since ilness and antibiotics taking (stopped in wednesday).
