Wladimir Klitschko has taunted Tony Thompson ahead of their world title showdown in Switzerland on Saturday night.
Thompson claimed that injury had hindered his performance in the duo's first encounter in 2008, but Klitschko insists that he remains confused by Thompson's revelations after being stopped by the Ukrainian in the eleventh round.
Klitschko said: "We sat here four years ago and you said you were going to beat me. You said you were going to knock me out.
"But after you lost the fight, you said you were injured. I don't understand why you said this after the fight."
Thompson responded to Klitschko's remarks and he insisted that he is ready to "try and crash the party" on Saturday night.
Klitschko will take his unbeaten run to 16 matches if he is successful in Berne.
