Canelo Alvarez scored one of the biggest paydays in the history of sports when he signed a deal with sports streaming service DAZN for 11 fights over the next five years.
The broadcast deal is the richest contract signed by an athlete since New York Yankees outfielder Giancarlo Stanton.
Boxing legend Floyd Mayweather Jr has stunningly attacked MMA star Conor McGregor as well as boxers Saul "Canelo" Alvarez and Oscar De La Hoya, giving the trio derogatory nicknames such as "Conor McQuitter" and "Golden Girl".
He successfully walked down Gennady Golovkin in their heated rematch last month en route to a unanimous victory over his rival, exorcising his detractors who wondered if he could defeat "GGG" clean.
Alvarez's first fight on DAZN will be against British challenger and WBA (Regular) champion Rocky Fielding on 15 December.More news: Donald Trump applauds Republican congressman Greg Gianforte for 'body-slamming' reporter
Lionel Messi, who earned $111 million a year ago, is likely to be his main competition for the highest-earning athlete title, but reports indicate that Alvarez could have earned upwards of $120 million for 2018 by the time of his debut fight with DAZN.
It will offer fans a monthly subscription service to watch the fights rather than having to pay hefty pay-per-view fees.
Mayweather is one potential opponent and, although the American has talked up a clash with UFC star Khabib Nurmagomedov, Alvarez would encourage the undefeated star to consider a repeat of their 2013 Las Vegas bout. "They're the two most important fighters in the world", DAZN executive chairman John Skipper said. "I always like giving the fans what they want to see, so if they want that third fight then we'll see about that".
"It's very important for me to finish this year off strong", he told SN. "We are committed to making this sport as accessible as possible and at an affordable price for all the fans". DAZN is charging its subscribers $9.99 per month, which - over time - translates to substantially less than the $85 pay-per-views to which boxing fans have become accustomed. "We'd like to bring that atmosphere back to this country, where every week there's good fights happening in Chicago, Boston, Los Angeles, Miami, Detroit or Madison Square Garden and people are excited about boxing".
