Yes. Federer dominated tennis for at least four years, 2004-2007. But after that he was overwhelmed by Nadal and then Djokovic.
In the end, statistically, Federer became the third best tennis player in the Open Era, behind Nadal at number two and Djokovic at number one.
History will record, if Pogi will be like Federer, then who will be Nadal and Djokovic
Federer wasn’t as popular during the years when he absolutely dominated — his popularity rose with Nadal’s arrival, because their styles were diametrically opposed. His popularity increased even more because of the French Open, which he couldn’t win due to Nadal. In the end, both Federer and Nadal became even more extremely popular (especially Nadal), because people started romanticizing their rivalry in contrast to Novak’s domination.
I don’t see any current parallel in tennis to Federer — unless something happens where Pogi fails to win Paris–Roubaix or Milan–San Remo due to a new young rider who races those two Monuments defensively and regularly beats him in one of them, while Pogi no longer competes in Grand Tours but only in classics.
Van der Poel doesn’t fit into that category because he also rides in an attractive/aggressive way. Overall, Pogačar gained popularity when Jonas beat him at the Tour, especially the second time. Likewise, even people who don’t like him are still excited about Tadej at MSR or P-R, because he doesn’t win but makes the race better.
