At 30-years-old, Mexican superstar Saul "Canelo" Alvarez is motivated to become the first Mexican boxer to be an undisputed four belt world champion. 

In December, he captured the WBC, WBA super middleweight titles with a domination of Callum Smith for a twelve round decision win.

He's back on Saturday night in Miami, when he faces mandatory world champion Avni Yildirim at Hard Rock Stadium.

If he wins, Canelo will then return to the ring on May 8th in a unification clash with WBO world champion Billy Joe Saunders.

And a win over Saunders might lead to a fall showdown with IBF world champion Caleb Plant.

When his career finally end, Canelo wants to be viewed as one of the best fighters in boxing history.

"When I retire we will see [where I land in history], right now I am making my career, I am making history and we will see where I am positioned when I retire...... yes, you have to look at it based on wins, based on numbers and championships, this is how it has to be done, ” Canelo told Erika Montoya.

In the last few years, Canelo has been under fire by a lot of critics - because they don't believe that he's facing the very best out there.

Canelo disagrees, explaining that he faces the best out there and makes them look ordinary.

“Almost all of the criticisms are unfair. Because when I beat the best they say that the opponent did not look the same as they did in the past. Why does that happen? Because with me they have a opponent who does not allow them do anything, an opponent who cancels them out. [The critics] want to find the weak side for everything, they never give credit. But I'm used to that," Canelo said.
