Vingegaard would be slaughtered, he's relatively bad at even the most mountanious monuments. Theres a reason he basically gave up on the classics. No chance.
I doubt Remco can ever do what Pogacar did today as well.
First, nobody can do what Pogacar did today... especially his output sitting down on sharp climbs is remarkable.
Secondly, not sure you are right on Vingegaard.
He's fine in the fight for position, he didn't have any real problem on the cobbled sectors of the Tour (the problems occurred on tarmac), he's explosive enough on short climbs (though not quite Pogacar's level), and is clearly strong enough... but Jumbo has not yet cracked the code of him performing in 1-day races.
They say they are working towards it though, so I wouldn't write him off quite yet, as all the pieces of the puzzle seem to be there.
