Former unified welterweight world champion Keith Thurman posted a series of rants involving Top Rank CEO Bob Arum and two prominent professional boxers: former lightweight and welterweight titlist champion Danny Garcia and eight-division world champion Manny Pacquiao.

Thurman Slams Bob Arum

In an Instagram post, Keith Thurman criticized Top Rank promoter Bob Arum. He slammed Arum for being one of the "worst promoters in the game."

"Bob, you're a piece of sh*t. You're one of the worst f*cking promoters in the game. All of your great fighters left your ass. Crawford, he about to leave your ass, " Thurman criticized Arum's lowball offers, in a report by Fight Sports.

The 32-year-old ranted that the Premium Boxing Champions (PBC), the same promoter of Errol Spence, could not close the deal with Arum. Thurman added that the Top Rank founder could not afford his price after his bout with Spence got canceled last year.

Earlier this month, Arum reported that someone from Thurman's camp talked to him about a possible fight with Terrence Crawford.

Barbershop Conversation's Frederick Hawthorne spoke to Arum about the possible $10 million-fight requested by Thurman's camp. The 89-year-old businessman had no direct response. But he said that it would not be easy to grant that amount of money for the Thurman-Crawford bout.

Thurman Shoves Danny Garcia

In a report by SB Nation, Thurman has been making waves with the fans after showing his new haircut to the public. In a live stream, he read a comment from a viewer who said that Thurman could be handled by Danny Garcia when they meet in a rematch.

Afterward, Thurman released a youtube video about Garcia. He told Garcia to stop lying because Danny could barely throw his punches. Moreover, Thurman, whose nickname is "One Time," called the Philadelphia resident a "timid" fighter who cannot pull a trigger.

Here's video posted by Fight Hub TV.

Thurman Warns Pacquiao over Spence

According to Boxing News 24/7, Thurman wanted to stage a rematch showdown with pound-for-pound king Manny Pacquiao. "One Time" said that the second bout would guarantee the Filipino boxer a different twist as he had learned his mistakes in their last fight.

Thurman lost his WBA 147-pound title to "Pacman" in July 2019 via a split decision.

It seems that Thurman has not yet moved on as he warned Pacquiao over his preferred fight against current IBF welterweight titleholder Errol Spence Jr.

Thurman said that the Spence he witnessed during their "Danny Garcia fight" will not be the same anymore for Pacquiao. He added that the 30-year-old American boxer would only "get better" as the arrangement nears.

"I want to fight Manny Pacquiao when I was 25 years old so I rushed because I'm living a dream. I got to make my dreams come true and it's the decision that I wanted, but I want to side it, man.. a once-in-a-lifetime opportunity, a once-in-a-lifetime experience, baby. I feel great about it even though I knew the stake," Thurman said in the opening of the video.
