Stuck? If anything his performance has declined!!!!
Back in 2011 both his climbing and his time trialing where way better. Right now machado doesn't make the top 30 of any GT and should work for kiserlovski who showed he has great climbing legs at the moment. And lets be honest, the time trial only matters for those fighting for a podium place. For the rest the mountains will be the ones deciding.
Also stop saying nonsense iZnoGouD, Costa has never been good on the high mountains so he has no chance of ever winning a GT. He reminds me of Kim Kirchen, possible low top 10 placings on a GT and good for 1 week races and 1 day races.
Tony back to his best this year (or at least very close to it surely). It's difficult to imagine anyone beating him in this form. Wiggins is the only one with a slight chance but the only likely match up will be at the Tour when Wiggo probably won't be at his best.
