Former heavyweight world champion Mike Tyson hailed "invincible" Floyd Mayweather after his dominant points victory over Manny Pacquiao at the MGM Grand in Las Vegas.
Mayweather was too classy for his Filipino opponent, with the scorecards of 118-110, 116-112, 116-112 showing how good the American was.
And Tyson, the former undisputed world champion, believes Mayweather is untouchable in the welterweight division.
"I think he (Mayweather) won the fight, he was pop-shoting Manny. Manny had a good beginning but he (Mayweather) controlled it," Tyson told Sky Box Office.
"He controlled the fight, he has great endurance (and) he did a real good job.
"It's his era, his time. He is in invincible mode now - no-one can stand with him at this particular moment."

Kell Brook has set his sights on a welterweight unification bout against the winner of Saturday night's long-anticipated fight between Floyd Mayweather and Manny Pacquiao.
After years of wrangling, the sport's two biggest names will finally get in the ring in Las Vegas where Mayweather's WBA and WBC straps will be on the line alongside Pacquiao's WBO belt.
Brook holds the IBF version of the welterweight title and, provided he successfully defends that against domestic rival Frankie Gavin later this month, the Sheffield fighter would relish a shot at unifying the division.
"I'm going to take care of Frankie Gavin on May 30," he told Sky Sports News.
"We've got pencilled in a fight in August but if the fight comes for September, I'd absolutely grab it with both hands - a unification fight with the winner.
"They're getting on, Pacquiao and Mayweather, so I'd love to lock horns with them before their time is out.
"I'm open to a unification."
Floyd Mayweather has warned Manny Pacquiao that his 'reckless' style could get him knocked out.
The American boxing welterweight made the claim hours before the two meet for what is being called the 'Fight of the Century' in Las Vegas on Saturday night.
"This is going to be an exciting fight," said Mayweather, who has a perfect 47-0 record with 26 knockouts and is acknowledged as the world's best pound-for-pound boxer.
"Our styles are totally different. He is very, very reckless. Every move I make is calculated. I'm always 5-10 steps ahead of my opponent.
"Pacquiao would be a better fighter if he wasn't so reckless. It's a gift and a curse. He's won a lot of fights by being reckless but being reckless can get you knocked out."
Floyd Mayweather and Manny Pacquiao have squared up to each other for the last time before their multi-million dollar contest in Las Vegas.
In front of a packed crowd at the MGM grand Garden Arena the two boxers weighed in ahead of Saturday's highly anticipated welterweight showdown.
Pacquiao tipped the scales at 145 pounds while Mayweather registered 146 pounds for what is being billed as the 'Fight of the Century'.
Dressed in a bright red track suit, Pacquiao waved and raised his fists into the air as he slowly made his way to the stage in contrast to Mayweather who was serious and focused, rarely looking up from under the brim of his 'Money Team' baseball cap.
After the weigh-in, the two welterweights moved to the front of the stage for the traditional stare down, the smaller Pacquiao looking up at Mayweather with a challenging smile while the stone-faced American stared straight-ahead unmoved.
"I have been fighting bigger guys like [Antonio] Margarito and [Oscar] De La Hoya," said the Filipino.
"It doesn't matter to me. I feel tomorrow that the Lord is always with me and gives me strength."
The showdown between the two best boxers of their generation has been more than five years in the making and at more than $400 million is expected to be the biggest-grossing prize fight of all time,
