Deep in a valley where Peru's snow-capped Andes melt into Amazon jungle, Wilder Diaz Angulo cuts open a football-sized cocoa pod and separates precious brown beans from their fleshy white placentas.

In the 1999/2000 edition Valencia CF blew Barcelona away in the first leg with a 4-1 home win, with Miguel ángel Angulo, Gaizka Mendieta and Claudio López scoring in a devastating performance.

It's unlikely that Cintron, who is used to being the hunter in the ring, will run from Angulo.
