Mexico vs. Mexico is the best rivalry in boxing.

This is the correct answer

Black on black

I agree. Alot of boxing biggest fights have been black vs. black.

the way mesicans fight against pinoys, it isn't much of a rivalry. it's more like a tsunami

mexicans have the better end of pinoys historically two pinoys won't change that especially when one of those two only faced one good mexican fighter in montiel

[lx!!]

I can't pinoys actually think they have better boxers than MEXICO. It takes more than a one roid user & nonito to even compare your selves to the best.

in regards to PRO boxing, mexico, puerto rico, usa and philipine are SUBDIVISIONS within gbp and top rank.
