Who's the greatest Mexican boxer of all-time?? It ain't Julio Cesar Chavez or Oscar De La Hoya ... boxing star Ryan Garcia tells TMZ Sports it's "without a doubt" Canelo Alvarez.
We talked to the 23-year-old, undefeated Garcia on the way out of the Canelo fight ... and we asked the Mexican American fighter whether 31-year-old Alvarez (57-1-2) should now be considered the best Mexican fighter of all-time.
"Oh yeah, without a doubt. He's the best," Ryan says.
If you know boxing, you know Mexico has been the birthplace of some of the greatest pugilists to ever lace up a pair of gloves.
