Pound for pound king Manny Pacquiao isn’t prepared to stoop down to the level of Floyd Mayweather Jr., who challenged Pacquiao to face him on May 5 by telling him via his twitter account - “Pacquiao I’m calling you out. Let’s fight May 5 and give the world what they want to see. My jail sentence was pushed back because the date was locked in. Step up punk.”

Pacquiao and his adviser Michael Koncz said the “Fighter of the Decade” will gladly fight Mayweather at the end of May emphasizing - “We are not ducking the fight. From a business perspective we are not going to throw away an additional $30-$40 million. Be a man (Floyd) and step up to the plate. Fight at the end of May and the fight is done.”

Top Rank's CEO Bob Arum, who promotes Pacquiao, is looking to construct a temporary outdoor venue on the Las Vegas strip to maximize the revenue for a Mayweather fight. The venue would hold 45,000 to 50,000 people and provide and additional $30-40 million for the event, but the earliest time period to complete construction is late May. The MGM Grand, where Mayweather is scheduled to fight on May 5th, holds 16,500.

"If we do it on May 5, we would be limited pretty much to the MGM Grand, and we would probably do a gate of $20 million, a record gate. If we did it in this new temporary arena for 45,000 people, we would do a gate of around $60 million. The difference is a minimum of $40 million. It's an extra $20 million for each fighter... That's still a lot of money," Arum told ABS-CBN.
