American rapper 50 Cent has waded into the debate over Canelo Alvarez, with the Mexican fighter having signed a $278 million deal with streaming service DAZN.
The Mexican secured the contract, which agrees the scheduling of 11 fights, after his win over Gennady Golovkin last month.
By achieving victory at the T-Mobile Arena, in Paradise, Nevada, Alvarez became the holder of the unified WBA-WBC middleweight title. He was previously the WBO light middleweight champion between 2016 and 2017.
Although BoxRec ranks the 28-year-old as the best middleweight fighter in the world, his reputation has been increasingly damaged by a failed drug test in March of this year.
A subsequent five-month ban meant his clash with Golovkin had to be pushed back over four months from its original date of May 5.
Many are dissatisfied that Alvarez has been rewarded with such a lucrative deal despite his connection to clenbuterol, a banned substance.
However, with the contract now formally announced, there are questions over who the Mexican will face in his upcoming bouts.
Floyd Mayweather has widely been suggested as a possible opponent, with the American inflicting Alvarez's only career defeat back in 2013.
The 28-year-old has suggested that Mayweather wouldn't fight him again, which 'Money' quickly responded to, calling Alvarez a 'cheating ass', and describing their fight a the 'easiest of his career', in an Instagram post.
He also claimed that he made in one fight what Alvarez will over his five-year agreement with DAZN, with the 41-year-old valuing his earnings from the clash in Las Vegas at over $300 million.
After his confident rebuttal, Mayweather will have been somewhat surprised at criticism from rap icon 50 Cent.
50 Cent also used Instagram to voice his opinions, arguing that Mayweather is angry at those who are 'on the way up' in the sport, and that the 41-year-old 'can't be the only winner'.
The pair have long endured icy relations, with a monetary dispute back in 2012 at the heart of their clashes.
They have regularly used social media platforms to exchange insults, with the boxer belittling the new series of 50 Cent's show Power earlier this summer.
Despite Mayweather previously showing a willingness to end the feud, this latest round of drama is sure to prolong the disagreement.
Regardless of how Mayweather chooses to respond to this latest attack, if he wishes to maintain his status as one of the sport's greatest, as 50 cent suggests, surely a rematch with Alvarez, a multiple world champion, would be a good starting place.
He is yet to respond directly to Alvarez's invitation for a rematch, with the Mexican having claimed that Mayweather would refuse to meet him in the ring again.
