I wouldn't count on Jonas or Roglic for Liege. (Roglic prefers stage races, and Jonas hasn't proven one yota in a hilly classic and he has ridden a few which suite him more than Liege).

Regarding the WC ITT, i think its of the same measure. Pog is also almost unbeatable in the tour TT, but he has never been close to even a podium in the worlds.
Last year should have suited Pogacar and he was 6th (40 seconds away from podium). So i think for Vingegaard the same will be true, they need to rely on fatigue or a very tailor made parcour to go for podium.
For the RR, Pog is more versatile than Vingegaard, so I understand him not being a pick for the win. ( but given his engine, he can work for some other Denmarkians who are capable of going for the win. I think helping his country can be done without needing to win it.).
