Julio Cesar Chavez Jr. believes the rivalry with Saul "Canelo" Alvarez has lingered on because Canelo is jealous.

Chavez Jr.'s father, former world champion and Hall of Famer Julio Cesar Chavez Sr., is regarded by most as the greatest Mexican fighter of all-time.

Because of his famous father, Chavez Jr. was an immediate attraction with the Mexican audience - which is why Chavez Jr. feels Canelo never liked him.

Chavez Jr. and Canelo will settle their differences on Cinco De Mayo weekend, May 6th, when they collide at the T-Mobile Arena in Las Vegas.

The HBO Pay-Per-View fight takes place at a catch-weight of 164.5-pounds.

"I think he's jealous because I'm Julio Cesar Chavez's son, but I'm guilty of having been born at the top, I did not ask to be the son of Julio Cesar Chavez," said Chavez Jr.

A few days ago, Chavez Jr. took some harsh digs at his rival - because Canelo stated that Chavez Jr.'s fan base was inherited from his father. 

"Well, I can only tell you that my wife is real, and his girlfriend is really not.. the one that Televisa gave to him," said Chavez Jr., referring to Canelo's ex Marisol González.

Chavez Sr. is surprised at how well his son has adapted to a tough training camp at the Otomí Ceremonial Center with Hall of Fame coach Nacho Beristain.

"The truth is Don Nacho Beristáin has been a very important factor in this camp, for the discipline that he's imposed on Julio. I do not know how Julio has endured [this tough camp], seriously, my son has surprised me, because Julio is difficult," Chavez Sr. said.

"I respect what Julio says, I respect what Canelo says but I do not agree with him. It's a dispute between them and they should fix it inside the ring."
