Heavyweight legend Mike Tyson has heaped praise on Anthony Joshua and likened the Briton to George Foreman ahead of his fight with Wladimir Klitschko.
IBF belt-holder Joshua faces Klitschko at Wembley on Saturday in a much-anticipated showdown that will take place in front of 90,000 spectators, with the vacant WBA title also on the line.
Despite his considerable success in the heavyweight ranks, including an 11-year unbeaten streak prior to his November 2015 loss to Tyson Fury, Klitschko is viewed as the underdog at the age of 41.
And former undisputed world champion Tyson is expecting Joshua to put on a show.
Tyson told Sky Sports pundit Johnny Nelson: "I am looking forward to this one. I'm excited we are going to get to see Joshua. He is just a beast. A big beast.
"Joshua reminds me of a young George Foreman. He is just wrecking anyone that's in front of him to get to the top. He is demolishing everyone."
Although Tyson believes Joshua is likely to prevail, he refused to write off the vastly experienced Klitschko.
He added: "In my mind, it's got to be Joshua early on - and I hope he does it - but if it goes late it could be Klitschko."
