Two years ago on Ventoux, Tour was already finished so UAE (they were weak too) didn't care about WVA.
Last year, UAE was really weak. People seem to forget that half of the team didn't finish the Tour. Pogacar was a lot of times, completly alone so UAE couldn't respond to WVA's attacks.
This year, they really have a strong team (at least on paper). WVA will not get more than 2 minutes before the start of Aspin and Soler/Majka/Yates can bring back WVA very easily even on Aspin.
I'm not saying Vingegaard will not attack in this stage. I'm just saying if he wants to attack on Toumalet, he needs to drop Pogi and do a 50 km solo.
