Michael Koncz, the advisor of Manny Pacquiao, has insisted that Floyd Mayweather Jr won't be the most dangerous fight of the Filipino's career.
The two biggest stars of boxing will collide in Las Vegas on Saturday night, but Koncz believes that Pacquiao's offensive style will end the 47-fight unbeaten streak of the American.
Koncz told BBC Sport: "It's a very difficult fight, but not the most dangerous fight.
"When it comes to the boxing ring, we respect Mayweather greatly. He's one of the great defensive fighters, but he hasn't fought anybody with the speed of Manny.
"I don't care how good the defence is, if it's throwing 10 punches and stopping nine-and-a-half. But throwing 80 punches means nobody can have a 90% ratio of stopping them."
Pacquiao will be defending his WBO welterweight crown, while Mayweather's WBC and WBA titles will be on the line.
