What i hold against Van Aert is going along in the rhetoric of him being absolute leader months in advance as if he were invincible. Then the fact that he knew during the race that it wasn't going to be his day, and yet he asked Evenepoel to work and waited until Evenepoel was smoked to inform Stuyven that he could ride his own race.
Welcome to the reality of TJV.
This is the same rider who already laid down a marker in the press before the Tour de France this year claiming he wouldn't ride in support of Roglic in the mountains "like last year". Before riding even harder to win his own stage in the Ventoux (once Roglic had crashed out). He also recently made more claims in the press about going for green next year (& needing support in the team for that).
I like 80% of what I see with WvA, but there's this other side which quite honestly often comes across as selfish & arrogant which I don't find helps anyone (himself included).
