Ok. I seem to remember at the 2002 WC the Asians going pretty berserk about Beckham and Beckham was a galactic for Real Madrid and an international model dating a spice girl so I’d argue Beckham was a bigger global brand than Son is.
If Beckham in 2002 had also been korean it wouldve been x100000 as big as whatever it is that youre referring to.
Beckham was a bigger international brand sure because more of the globe were "fans" but he didnt mean anything close to what Son means to korea.
