A World Cup crowns you king of the world for your nation. Five Champions Leagues are club flexes that can't touch that legacy.
You can buy a Champions League squad with enough cash, but you can't buy a national team. Carrying your actual homeland every four years is a completely different pressure.
World Cup glory is universal trust for a nation; global sponsors, fans, and markets bend toward it. Five Champions Leagues stay club wealth, not the same worldwide claim.
Imagine the World Cup as a single shared heartbeat for a nation; five Champions Leagues are bright orbits, yet only the World Cup reverberates through history.
