Mayweather blasts Pacquiao after talks collapse

Floyd Mayweather Jr. launched a verbal jab at Filipino WBO welterweight champion Manny Pacquiao after talks to revive their planned mega-fight collapsed.

"Throughout this whole process I have remained patient, but at this point I am thoroughly disgusted that Pacquiao and his representatives are trying to blame me for the fight not happening when clearly the blame is on them," Mayweather said.

"First and foremost, not only do I want to fight Manny Pacquiao, I want to whip his punk behind."

A World Boxing Organisation welterweight title bout slated for March 13 against Mayweather in Las Vegas was expected to be among boxing's biggest revenue-producing fights.

The bout, considered to have matched the best pound-for-pound boxers in the world, was called off in midweek when Mayweather's demand for Olympic-style dope testing was rejected by Pacquiao.

Mayweather said he offered a compromise but Pacquiao refused to bend.

"Before the mediation, my team proposed a 14-day, no blood testing window leading up to the fight. But it was rejected," said Mayweather.
