Negotiations for an all Mexican mega-fight between WBO super welterweight champion Canelo Alvarez and former middleweight champion Julio César Chávez Jr. have been on going for several weeks.

If the fight is consummated it will take place on May 6th at a catchweight of 165 pounds. With the weight agreed upon, the biggest stumbling block is money.

Canelo took to his Twitter account this evening to tell Chavez to sign the contract and make the fight happen.

"Don't let them treat you like a kid.  Your people have had the contract since yesterday. Sign it so we can make the fight happen," Alvarez said in a Tweet that was translated from Spanish and directed to Chavez's account.

Chávez has a different account of the negotiations and believes that the offer from Canelo's team is for less than he is entitled. 

The son of the legendary Julio César Chávez Sr. went as far as to say that Canelo isn't in any position to make outrageous demands after dropping his WBC middleweight title instead of facing Gennady Golovkin as mandated by the sanctioning body.

The current plan is for Canelo and Golovkin to fight in September but that fight isn't set in stone and some people are skeptical that the fight actually happens especially since that bout has been put off on more than one occasion.

"The people know that what you are trying to do to a fighter you never intended on fighting (Golovkin) isn't fair. You should be humble Canelo," Chávez responded in a tweet translated from Spanish over the social network.

With Canelo's promoter Golden Boy Promotions and Chavez's adviser Al Haymon embroiled in a lawsuit, an agreement for Golden Boy's top fighter to face one of Haymon's highest paid clients would certainly be noteworthy.

Golden Boy CEO Oscar De La Hoya, who promotes Canelo, also took to the social networks to apply pressure on Chavez Jr. 

“Junior, we gave you the opportunity to fight Canelo. Your manager has the contract. Stop tweeting lies, go sign and we’ll be on for May 6,” tweeted De La Hoya.
