Culiacan, Sin. The undefeated Mexican boxer, Julio Cesar Chavez Jr., said he was surprised by the comments made by Oscar De La Hoya on his personal twitter, where he voiced his criticism about Julio's last fight against Billy Lyell from last Saturday.

Chavez Jr. (42-0-1, 30 KOs) picked up a unanimous decision win over Lyell before ten thousand people in a packed stadium in Culiacán Sinaloa, and he scored a record audience at Fox Sports in America and TV Azteca with millions of viewers following their battle.

De la Hoya wrote on his personal twitter that saw the fight Chavez Jr. and believes Julio has nothing, no power in his fists and wished him the best.

"I'm surprised that De La Hoya could see two fights at the same time, mine and the Bradley-Alexander, but I am grateful to have contributed to that. I've broken the record audience number on Fox Sports for those who tuned in to see my fight," said Julio Cesar Chavez from his home in Culiacan, Sinaloa.

Chávez, the son of the best Mexican fighter of all-time, said that he recalled that when De La Hoya was developed his boxing career, neither he nor his father criticized him when unknown rivals such as "Chicho" Valenzuela sent him to the canvas.

"Nor did we criticize the knockout to [Bernard] Hopkins, who after the fight became a partner in his company, let alone when he sat on his stool against Manny Pacquiao," Chavez recalled

And then Chavez launched a challenge.

"I call on Oscar De La Hoya to pick up the gloves and lets fight at middleweight in September. And to give De La Hoya more motivation - I bet my purse that I'm going to send him to his final retreat from boxing. And then I'll wish him well in his career as a promoter," concluded the official challenger for the WBC world title at middleweight.
