Obviously, road cycling is the most important discipline in cycling, so it makes no sense to suggest that 10 cyclocross riders could win a world championship and don't even try.
Only four of them can achieve it: Van der Poel, Van Aert, Pidcock, and Nys. And everything indicates that Vaert may retire without winning one, despite having had opportunities like Alaphilippe's World Championships, which were also races that suited him well.
I never thought I'd read that for undervaluing Pogacar, the same year he finished Paris-Roubaix ahead of Van Aert

. If Pogacar beat Van Aert in Paris-Roubaix, are we really supposed to believe that riders like Vandeputte could win a road world championship against him?
That last statement makes no sense. Not even Pidcock can beat Pogacar at Strade Bianche, so how are seven other cyclocross riders going to beat him in any road world championship?
Those riders wouldn't even beat Ben Healy in a road world championship. They're not good on the road; otherwise, they'd already be winning there.
The bottom line is that no matter what Pogacar does, some people live in a dichotomy.
If he wins, they obsess over his "clinical" performance, but on the other hand, they find fault with him, saying he's not that good. They have this constant need to find the negative side of everything, to the point of contradicting themselves. It's either he's not that good or it's all just "clinical."
This happens to all the greats of his generation. The example I gave of Messi is very clear. Before, they demanded the World Cup from him; now those same people say the World Cup isn't so important anymore, and they'll always find some excuse or complaint. Jordan is also criticized for not winning more rings than Chamberlain or for some statistic that LeBron has. And if the debate shifts to the positive side, they'll talk about "clinical" performance or controversial refereeing decisions. It's very boring.
It is the cyclocross cyclists who usually want to prove that they can compete and win on the road.
Pogacar doesn't have to prove anything in cyclocross.
