It's notable only in the USA, the nation where american football and baseball are the most followed sports and soccer is a second-tier sport. The Cosmos were the most expansive club in the world? Because thay took out Pelè from retirement? I doubt it. Perhaps the most expansive in the States, not in the entire world. I'm not here to offend anyone, I'm just here to open your eyes: outside of the USA nobody is going to care much about the Cosmos, face it.
