The legendary Julio Cesar Chavez Sr. believes his attendance record would be broken if a deal is finalized between his son, Julio Cesar Chavez Jr. (49-2-1, 32KOs), and Saul 'Canelo' Alvarez (48-1-1, 34KOs).

The two sides are in serious negotiations for a pay-per-view fight on May 6th and a catch-weight of 165-pounds. Chavez, who competes at super middleweight, would have to move down by three pounds. And Canelo - who holds the WBO junior middleweight title - would have to go up by eleven.

Chavez Jr. returned to the ring last Saturday night and won a hard-fought ten round unanimous decision over Germany's Dominik Britsch (32-3-1, 11KOs) in Monterrey, Mexico.

In September of 1993, there were 59,000 fans who came to the Alamodome in San Antonio for the clash between Chavez Sr. and Pernell Whitaker for the welterweight title of the World Boxing Council.

"They're in discussions to see if they can reach an agreement and the talks are progressing. Let's see what happens," Chavez Sr. told ESPN Deportes.

"It would be great [if a deal was finalized], something for all of the Mexicans who have waited for this fight for a long time. I think that fight would break my attendance record at the Alamodome or wherever they want to do it. The attendance record would be broken in a closed stadium, not in an open stadium."

At the moment there appears to be no issues with the catch-weight, but the exact terms of the money is the real issue being worked out at the moment. Chavez Jr. received an initial offer for the fight and issued back a counter-offer. The two sides will continue their negotiations over the next couple of weeks.

The locations being considered are Las Vegas, Los Angele and Texas. In the state of Texas, Canelo has done some very big business with 51,000 fans for Liam Smith, 31,000 with James Kirkland and 40,000 with Austin Trout.
