Wladimir Klitschko says his training camp is going to plan despite difficulty finding sparring partners to replicate Tyson Fury's threat.
Klitschko's delayed fight with Fury goes ahead in Dusseldorf on November 28, when the champion's WBA, WBO and IBF heavyweight titles will be up for grabs.
The calf injury that forced a five-week postponement is now "100 per cent healed", according to the Ukrainian, who had a public workout in front of the cameras at his Austrian training camp on Tuesday.
And Klitschko says his biggest problem has been unearthing anyone who can mimic Fury's size and switch-hitting skills in sparring.
"It's always challenging to find sparring partners simulating your opponents size-wise, weight-wise and style-wise," he told Sky Sports.
"It's very difficult to find somebody who's 6ft 9in, who can fight in a southpaw and regular stance with the same capability of movement.
"It's challenging, but so far so good. We've got good guys and I'm happy. You cannot be always satisfied, you can always dream about something else, but so far so good. We're in a good way."
