"He's very delusional." Iron Mike Tyson is very pissed at Floyd Mayweather Jr.'s latest claim. According to the undisputed welterweight king, he's the best fighter in the history of boxing and quipped that he's even better than Muhammad Ali. 

Mayweather said that he had beat more world champions than any fighter in history. He added that no boxer has "accomplished what I accomplished at all." 

Tyson isn't a big fan of his statements. He said that if he's near the skill and ability of Ali, "he'd be able to take his kids to school by himself." 

The former heavyweight champ also reiterated that "greatness is not guarding yourself against the people; it's being accepted by the people." 

Iron Mike didn't stop there, "he can't take his kids to school by himself, and he's talking about he's great?" Quipped an irritated Tyson as he finds Mayweather's comments unacceptable. 

"He's a little scared man. He's a very small, scared man." The 53-year-old boxing Hall-of-Famer was unquestionably speaking for fans that are defending Muhammad Ali's legacy.

Mayweather, on the other hand, said that he respects the legendary boxers but insisted that his achievements in the ring cement him as the best. 

He even challenged his fans to "go back as far as you want to go back." Referring to former fighters that can equal his boxing resume. 

Mayweather also added that Sugar Ray Robinson, Sugar Ray Leonard and Joe Louis are not better than him. Bold statements like these are what irks most of Floyd's staunchest critics. 

Floyd Mayweather is rumored to fight an unknown opponent in China next year. The South China Morning Post reports that a press conference will announce details of the scheduled fight next year. 

Rumors of him fighting Manny Pacquiao has surfaced in the past months. However, his camp has strongly emphasized that Floyd is not interested in fighting the Filipino pugilist.
