Former cruiserweight and heavyweight boxing world champion David Haye has heaped praise on the current crop of heavyweight fighters, but not before insisting that he could beat them all if he was still active.

The former British boxing star is one of only three boxers in history to have unified the cruiserweight world titles and become a world heavyweight champion.

Having fought the likes of Wladimir Klitschko and Enzo Maccarinelli, Haye enjoyed an incredible career in boxing.

Haye and Maccarinelli met in an all-British world cruiserweight title fight in 2008 as the two heavy hitters went to town, with The Hayemaker hitting harder and finishing the job in just the second round.

Haye had marked the fight to be "the final piece" in his cruiserweight puzzle as he unified the belts and set his sights on his childhood dream of being the heavyweight champion.

He was supposed to get his shot at his first heavyweight belt against Klitschko; the fight was confirmed, but Haye was forced to pull out because of a back injury.

Haye then claimed his first heavyweight title after defeating Nikolay Valuev, having weighed in at almost 100 pounds less than his opponent.

The incredible difference is to this day the biggest "weight-upset" in the history of boxing.

Having recounted only some of his accolades, he is certainly one to hear from when talking about contemporary boxing.

He spoke about the current crop of heavyweight boxers, saying to DAZN: “There’s so many good fighters and even the young crop coming through like Joe Joyce and Daniel Dubois.

"There’s a lot of homegrown talent and at the top of that there’s Tyson Fury, and just behind him is Anthony Joshua.

“I’ve never known a time when there’s been such a depth of quality. Each one of those you could make an argument on why they’ll become a world champion.

"Daniel Dubois’ punch power is through the roof. Joyce can pretty much walk anyone down. There wasn’t that depth that there is now.”

He added: “I’d have loved to see how I’d have got on today.

“In my mind, I would’ve beaten everybody, but we’ll never know.”
