Potential Floyd Mayweather Jr opponent Karim Mayfield has raised eyebrows after claiming he "whooped" both Amir Khan and Manny Pacquiao in sparring.
The unbeaten Mayweather casued a huge stir after his victory over Pacquiao by naming Mayfield and Andre Berto as those leading the chase to fight him next and Mayfield (19-2-1-KO11) believes he is the man most deserving of a shot at 'Money'.
The 34-year-old said: "No disrespect to Andre Berto, he's a good fighter and we have a mutual respect for one another, but he's not as durable as I am. Berto has two losses against opponent's Floyd has already defeated.
"I've never been dropped, battered or bruised in any of my fights. I bring a rough style to this fight, a style the fans want to see Floyd up against. In addition, I'm confident we can bring a big crowd to Las Vegas. It's only an hour fight away.
"Every time I sparred Amir Khan at Virgil Hunter's gym, I put hands on him. So bad that Virgil had to stop the sparring sessions. Khan has also been brutally knocked out twice by Prescott and Garcia. The man has no chin and he wouldn't last 12 rounds with Money Mayweather. He's definitely the safer route.
"I've been the ring with everyone. I soundly beat Herrera, I whooped Pacquiao and Khan in sparring. Shawn Porter refused to step in the ring when he had the choice to fight me or Erick Bone with only one day notice. A lot of fighters have ducked me because I'm a serious threat to anyone."
Californian Mayfield was beaten twice in 2014, suffering points defeats to Emmanuel Taylor and Thomas Dulorme.
Khan has been particularly vocal in expressing his desire to fight the 38-year-old Mayweather, while current welterweight world champions Kell Brook and Keith Thurman have also confirmed their interest.
