As most of you know, Rafa went to the big soccer clash between Real Madrid and FC Barcelona (sitting next to Roger Federer) last Sunday.
There was a HUGE
banner with the text:
Estirpe Española. Caballero Madridista'
Apparently, it means something like:
man of Spain, knight of Madrid.
Cabellero means "knight" or "gentleman"
