Floyd Mayweather took to Instagram Wednesday to launch the latest salvo in his rivalry with Manny Pacquiao. The undefeated world champion posted a video of the moment that Juan Manuel Marquez knocked out Pacquiao during their fight in 2012.

Set to Queen’s “Another One Bites The Dust,” Mayweather’s Instagram video featured a loop of Marquez knocking down Pacquiao, shot from various angles. By late Wednesday morning, the video had already garnered more than 60,000 likes. Mayweather captioned the footage with a link to his “Money Team” faction’s website.

Mayweather and Pacquiao regularly trade barbs on social media. Pacquiao questioned his rival’s desire to fight in September, which prompted Mayweather to post photos of an unconscious Pacquiao to his Twitter account. “Miss Pac Man is broke and desperate for a pay day. Your Pay-Per-View numbers are a joke,” Mayweather wrote. In response, Pacquiao dissed the insults and said Mayweather should “fear God.”

“I’m not affected by it,” Pacquiao told a TV station in the Philippines at the time, according to Agence France-Presse. “I pity him and I pray that someday he would change his ways.”

Pacquiao earned a convincing victory over previously undefeated challenger Chris Algieri on Nov. 22, knocking his opponent down six times en route to a win by unanimous decision. A week before that result, the WBO world welterweight champion reiterated his desire to fight Mayweather.

"I do have one specific goal, and that is to give the boxing fans the fight they have always asked for," Pacquiao said, according to ESPN. "I want that fight too."

The prospective fight may hinge on whether Pacquiao is willing to commit to a rematch clause. “My understanding is that Floyd is insisting on the rematch if Manny beats him, which I believe he will. That’s okay with us,” trainer Freddie Roach said, according to the Daily Mail.

Pacquiao has spent years angling for a fight against Mayweather. A match nearly took place in 2009, but negotiations fell apart over disagreements concerning revenue shares and drug testing. Mayweather’s camp has insisted that Pacquiao submit to a drug test before any fight, while Pacquiao’s camp has resisted that stipulation.
