Floyd Mayweather and Manny Pacquiao weighed in as 11,500 fans watched on ahead of the most lucrative fight in history in Las Vegas on Saturday. Entry to the weigh-in at the MGM Grand Garden Arena on Friday was $10 (£6.60), although tickets were changing hands on the resale market for $800 (£530). The fight is set to generate an estimated $400m (£265m). American Mayweather scaled 146lb – one pound under the welterweight limit – and Pacquiao of the Philippines 145lb. The pair will fight for the WBC, WBA and WBO welterweight titles. “I believe that with my skills, I’m going to be victorious,” said the 38-year-old Mayweather, who is unbeaten in 47 professional fights. “I don’t take anything away from Manny Pacquiao, he’s a solid fighter and it will be an intriguing match-up. “But after Saturday, I’ll still be ‘TBE’ [The Best Ever].” Pacquiao, who has 57 wins and five defeats from 64 pro fights, said: “It’s a great responsibility for me to give enjoyment to the fans. The fans deserve to have a good fight, whether they are a fan of Mayweather or Pacquiao. “The Lord will always be with me and strengthen me and deliver him into my hands.” Asked about the difference in size – Mayweather is 5ft 8ins and Pacquiao 5ft 6½ins with a reach difference of five inches in favour of the American – the Filipino southpaw added: “I’ve been fighting bigger guys – Oscar De La Hoya, Antonio Margarito… it doesn’t matter to me.” The MGM Grand was abuzz the day before the fight, with people queuing to get into the Garden Arena hours before Mayweather and Pacquiao, 36, stepped on the scales. It was the first time tickets had been sold for a weigh-in, with proceeds going to charity, and those that bought them were given a two-hour show. Mayweather and Pacquiao have won world titles in five and six different weight divisions respectively. Whoever wins this weekend will be able to claim they are the best fighter of their era.
