Celestino "Pelenchín" Caballero of Panama has continued the verbal assault on Puerto Rican colleague Juan Manuel López, current world featherweight (126 pounds) champion of the WBO. 

And the fact is, for Caballero, "Juanma" López is nothing more than a coward who built his record (29-0, 26 nocauts) by facing fighters that he could bully in the ring.

"I continue think that López is a chicken. For two years I've been challenging him to a fight and he does not dare to face me because he knows that I am going to knock him out easy," indicated Caballero.

The statements of Caballero were given barely a few hours after López managed to retain his world featherweight title, after knocking out Philippine contender Bernabé Conception in two rounds on night on Saturday in San Juan, Puerto Rico.  Lopez will now face Rafael Marquez on September 18 in Las Vegas.

"Now López calls on Márquez who is already beaten up.  Why doesn't he collide with the 'Tower of the Hell' if is a man?," added Caballero.
