The veteran boxer and heavyweight champion Wladimir Klitschko is expecting a tough fight against unbeaten challenger Tyson Fury.

The Klitschko vs Fury fight is set on Nov. 28 at the Esprit Arena in Dusseldorf, Germany, per BoxRec. "Dr. Steelhammer" already anticipates a difficult match for him, Boxing Scene noted.

The boxer, who holds the World Boxing Association, International Boxing Organization, World Boxing Organization and International Boxing Federation crowns, explained why he has a reason to dub it as "one of the hardest fights" in his entire career.

"This time the opponent will be taller, heavier, with very long arms, and he is also younger and has great ambitions. This guy really wants to prove himself in the ring and confirm what he keeps telling everyone, that he's the best in the world," Klitschko said.

The seasoned fighter also shared that Fury's style and some "physical conditions" will also add to the challenge.

Yet, even though he perceives that this bout is something that will challenge him, he can still a great thing out of it. The heavyweight fighter believes it is a match that will be worth seeing and that they will not be "bored."

Although "Dr. Steelhammer" said that it will be hard on him, he also hinted that it would also be difficult for Fury to beat him. Recently, a separate Boxing Scene article noted that the Kazakhstan-born boxer even posted images on his social media account with a quote that reads: "Look what I found! Fury in the Slaughterhouse, one of my favorite bands. At camp I'm working on my own cover version."

Fury to retire if he wins?

The mandatory challenger, who posts a 24-0 win-loss record, per BoxRec, is even considering to retire if he successfully beats the heavyweight champion this month, another article from the site noted.

"I'm not really planning beyond this. This could be the end. My ultimate ambition was to be the best fighter in the world. Beating Klitschko will cement my place as the best fighter in the world," Fury told BBC Radio 5 Live Afternoon Edition.

The 27-year-old fighter even stated that by doing so, he would be able to create history, as he will be doing "something that's never ever been done."

If he wins their bout on Nov. 28, he will be able to capture the four championship heavyweight titles from WBA, IBO, WBO and IBF in just one spectacular moment. Will he really not attempt to defend these crowns even for just one time?
