Former undisputed heavyweight champion Mike Tyson has given the names of his favorite fighters in the sport - and two-time heavyweight champion Anthony Joshua is not one of them.

Tyson is a big fan of the big men like Tyson Fury, Deontay Wilder, Andy Ruiz - and he likes the smaller fighters like Vasiliy Lomachenko and Gervonta Davis.

"I respect Tyson Fury, I respect Deontay Wilder, I respect all of those guys," Tyson explained on his own podcast, Hotboxin'.

"Andy Ruiz also, this guy named Lomachenko - he's a f--king animal, man. He's a master, it's like he's dancing. There's also Gervonta Davis, there's quite a few guys that are good fighters."

Tyson has been all over the boxing headlines as of late, after revealing that he's very interested, at the advanced age of 53-years-old, to step in the ring again.

Retired since 2005, Tyson has been training to get himself in top form. He would like to take part in exhibition fights to help raise money for charity.

When discussing the current state of the sport, Tyson believes the top promoters are not allowing their best fighters to face each other.

The sport would get a tremendous boost, says Tyson, if promoters allow the best to fight the best.

"The situation is whether they will fight each other. Promoters are not allowing them to fight each other. I’d love to see them fight each other but the promoters don't want to do it," Tyson said.

"It (boxing) is very political now. That's why I think in the next couple months or so you're going to find that there are some new players in the game and it's going to get really serious."

The top promoters are aligned with rival platforms, which makes it difficult to set up the top fights. Top Rank is exclusive with ESPN, while Premier Boxing Champions works with Fox Sports and Showtime, and streaming service DAZN has deals with Golden Boy Promotions and Matchroom Sport.
