He coming to the giro to win it. And will be in top shape for sure. He is not like Pogacar that can win the giro on 90%
What I fear is that he can’t hold that from to the Tour. Because he have no history of keeping form over that long. He always bad in the second grand tour.
He has done 2 back-to-back GT's only once in 2018. And if I remember correctly, he was a good helper for his brother.
Don't think we have any history to suggest that he's bad in hs second GT. Besides he only needs to be good for 2-3 stages in the second half of the race.
