His results since winning the NC:
DNF Tour de France (fatigue)
18th Olympics ITT
23th Olympics RR
10th Renewi Tour
20th GP Quebec
DNF GP Montreal
He's lucky Italy lacks options for the WC road race.
I'll let him off a bit due to him having just moved teams, but his recent results should of course affect the role and freedom he will have during the WC. Still, he's had one of his more consistent seasons this year, so even if there had been depth among the Italians, he'd probably still be selected.
