Mexican superstar Saul "Canelo" Alvarez aims to turn the tables on knockout artist Edgar Berlanga on Saturday, saying he'll be looking for a knockout himself as he defends his three super middleweight world boxing titles in Las Vegas.

"It's easy to say you'll knock me out, but it's much more difficult to do it," said Alvarez, who puts his World Boxing Association, World Boxing Council and World Boxing Organization belts on the line against the top rated WBA contender in the 168-pound division.

Alvarez was stripped of his International Boxing Federation belt in July when he opted to take on Berlanga rather than IBF mandatory challenger William Scull.
