Also note that Martinez spent a long time in Europe as well so that would explain his deftness in the Spanish language. As for him beating Chavez I'd say that Chavez is made for him, a guy who comes forward, leans forward, no upper body movement, and no jabs.

Moreover since Chavez is a body puncher and Martinez fights in a semi crouching style its going to be very hard for Chavez to find the body of a smaller man fighting even smaller. I only do have one apprehension and that is the weight of Chavez, this wouldn't make me nervous if in boxing we still would insist on same day weighting.
