Former world heavyweight champion Larry Holmes believes Anthony Joshua can become one of the greatest fighters of all time if he can maintain his current level.

British ace Joshua currently holds the WBA, IBF and IBO world heavyweight titles and he has won all 19 of his professional fights to date by knockout, including his success against Wladimir Klitschko in April.

Next up for Joshua is a clash with Bulgarian Kubrat Pulev at Cardiff’s Principality Stadium on October 28 and former champ Holmes believes the 27-year-old has all the credentials to become one of the all-time great boxers.

“I got to be heavyweight champion of the world when I was 30 years old and this guy (Joshua) is just at 27,” Holmes said.

“I think he has a great opportunity to make himself known as one of the greatest fighters of all time.

“You’ve always got to think you are better than the next guy. If he keeps going I think he’ll be strong and I that’s what’s going to make him a great fighter.”

Holmes is hopeful Joshua will fight WBC champion Deontay Wilder in the near future, as he believes a fight between those two will be too close to call.

“I’d flip a coin because both guys are big and punch very well,” Holmes added. “That’s one fight I really don’t want to call. Wilder’s got a good punch, which they both do, and they can both take a punch.”

Joshua must first focus on beating Pulev later this month and he is priced at 1.04 to achieve that feat, while the Bulgarian is available at 13.00 and the draw is on offer at 26.00.
