British heavyweight Anthony Joshua has predicted that Wladimir Klitschko will knock out Tyson Fury in Saturday's showdown in Dusseldorf.
Klitschko became world heavyweight champion in 2006 and since then has successfully defended his title 23 times.
Fury, who is undefeated in 24 bouts, is hoping to take the Ukrainian's WBA, IBF and WBA belts this weekend.
However, Joshua believes that Klitschko's experience will guide him to victory in the ring.
"How great would it be if Fury won? But I'm picking Klitschko, in round five or six," Joshua told BBC Sport. "Fury will come out fighting, the adrenalin will get to him, take over his body.
"He throws a lot of punches and moves a lot for a big guy but Klitschko has got so much experience, he's been defending his heavyweight title for 10 years, and it only takes one shot."
Klitschko has 64 wins from 67 fights with 53 knockouts.
