This past Saturday night, Anthony Joshua (20-0, 20 KOs) retained his WBA, IBO and IBF world heavyweight titles with a tenth round stoppage win over Carlos Takam before a crowd of 78,000 at Principality Stadium in Cardiff.

There has been a lot of critics over Joshua's performance and the fight itself.

Joshua appeared to be winded in the later rounds, and the majority of the crowd was unhappy with the stoppage - which saw referee Phil Edwards jump in way too soon to wave off the contest as the two boxers were trading punches.

Promoter Frank Warren was far from impressed.

He felt Joshua, at 254-pounds of muscle, was far too heavy

Warren was offended when Takam was being compared to heavyweight legend Evander Holyfield. And Warren let out a belly laugh was he discussed how some people have compared Joshua to another heavyweight legend, Muhammad Ali.

“He was very heavy,” Warren said to The Express.  “It is what it is. You expect him to beat a 36-year-old, who was coming in as a last-minute replacement substitute.

“But to compare him, Takam, to Evander Holyfield’s style, come on, if he’d [Joshua] been in there with Evander Holyfield, he would have come out with the belt. He would have caught him. If he would have caught him, he would have known about it. He must get embarrassed, AJ, that people compare him to [Muhammad] Ali.

“Let’s be realistic. He’s a great young fighter, Anthony Joshua, but he ain’t no Muhammad Ali. Muhammad Ali was around for a long, long time, not [just] 3 fights. Muhammad Ali was considered a good fighter after beating Sonny Liston twice.

“They all thought he was nothing. So, don’t compare him with that. The one thing he hasn’t got, which Muhammad Ali had, is one of those [Warren points to his chin], because he gets caught. It’s being disingenuous to Anthony.

“These guys need to calm themselves down. You got eyeballs; watch what you see. He beat Charles Martin. Charles who? For a belt the IF nicked off of Tyson Fury, and he had an exciting fight against Klitschko.

“But let’s get it right. Klitschko, 18 months before, was taken to school by Tyson Fury; you look at that. You look at Dillian Whyte, who banged him on the whiskers. You can see there’s chinks there.”
