Oh please. It was always secondary. The lower teams have gotten better and you don’t see as many beatings or a few teams run the entire show anymore.
There’s so much wrong on your post I don’t even know where to start but let me try...
No, it wasn’t secondary. The World Cup used to be the icing on the football cake, the most glorious and sought after trophy of them all. It was that way until the 00’s. If you think otherwise you’re simply too young to understand why. If you haven’t lived through the 70’s, 80’s and 90’s and watched how full of talent all the big nations were during those decades and I mean REAL talent not the fucking overrated Pogbas and Dybalas of the world you’d know.
And btw, lesser teams didn’t get better, they got more physical, they became better athletes. And that took a hit on the big teams as well as they had to keep up physically while compromising their technique and skills.
