The Son Heung-min Effect Begins

When Son Heung-min joined LAFC in August 2025, few expected an immediate seismic shift. Yet within days, his jersey became the second best-selling in MLS history, trailing only Lionel Messi .

The impact extended beyond LA: MLS viewership surged 29% to 3.7 million weekly, with Son and Messi credited as key drivers . Even Tottenham reportedly faces $80 million in lost revenue .

The numbers reflect a deeper truth: Son brought more than goals. He brought identity. As one fan noted, 'I wasn’t an MLS watcher, but now I tune in for LAFC' . His presence reshaped fan demographics, drawing in Korean families, celebrities, and casual viewers alike. The league responded with a dedicated 'fancam' broadcast for Korean fans, ensuring every Son moment was captured . This blend of global appeal and local resonance turned a transfer into a movement .

On-Field Brilliance and Team Transformation
