Keith Thurman sure has a lot to say against Manny Pacquiao ahead of their welterweight fight in Las Vegas. And while Thurman has been saying a lot smack, Pacquiao plans to let his fists do the talking and show Thurman that he is biting off more than he can chew.  

In a recent interview, Pacquiao said in his native language that he is motivated for his next fight because his opponent decides to be chatty and all that, adding that bragging isn't exactly his thing.  

Thurman, who has so far been undefeated happens to be a decade younger, and has already vowed to send the Filipino fighter into retirement, similar to how Pacquiao forced Oscar De La Hoya to call it quits.  

Pacquiao has no plans of slowing down. He has been on a roll in his last two fights, defeating Lucas Matthysse in the seventh round and reigned over Adrien Broner in a 12-round fight. He admits the upcoming fight is a big challenge, considering he is fighting someone 10 years younger, but Pacman wants to prove that he still has it.  

Meanwhile, Hall of Fame trainer Freddie Roach is eager to make Pacquiao hit his second half of training camp sooner. Roach wants the Pacman to arrive at the Wild Card Boxing Club in Hollywood at least six weeks before his next scheduled fight.  

Meanwhile, Hall of Fame trainer Freddie Roach wants Manny Pacquiao to hit his second half of training camp much earlier. "I would like to see him earlier, like six weeks before," said Roach to the Manila Bulletin. 

Conditioning coach Justin Fortune is already on his way to Manila, Philippines to start working with Pacquiao, and notes that they have less than eight weeks of camp to prepare. According to Roach, he has about eight sparring partners all set for the July 20 fight. 

Earlier this week, the two boxers were involved in a two-city media tour in the United States. In their recent US press tour, Thurman was 21 pounds overweight, and proceeds to claim that he has "a bit of a sweet tooth." He's still adamant on retiring Pacquiao from the sport and calls the Filipino boxing champ a "T-Rex," and that "he loves to quote the Bible and he is getting crucified." 

Thurman sure has a lot of fan trash-talking Pacquaio but the latter plans to make him pay.  

"I will have him eat his words," Pacquiao said.
