I don't think in the past that the nationality based DPs have brought out the demographics they are intended to. Winning brings out fans. I think chicharito would only have the value that his high quality play brings. Are Slovakians flocking to YS?Thinking back to the Chicharito to OCSC rumors, what about one of the bigger Mexican stars playing in NY? Mexicans come out like few others to cheer on their own. Would you hand over $10 mil for Dos Santos as a third DP? Or $6 mil for Hecor Moreno at center back? They'd probably pay for themselves in ticket sales alone.
ETA: As an avid USMNT supporter, it does make me sick to cheer for them, but they'd be incredibly valuable in the New York market.
