He had several allies the first time around, and that group probably goes all the way to the line if Pedersen had not punctured a few minutes earlier, causing him to miss the split and forcing Skjelmose to close to gap.I don't think so. First time up was too soon and even if he had dropped Van Aert, he'd have been caught again. He needed a strong ally, and I think his best bet was to lean on and cooperate with Belgium to control the race with a defensive posture on the first laps, marking Evenepoel's attacks. Then drop the hammer on the last ascent or when the moment is right on the lap until it. It's not like he'd risk Van Aert countering such an attack by Evenepoel.
Anyway, it doesn't really matter. The point was that he had the form and legs to win (according to himself), and his preperation was not half-assed.
