Wladimir Klitschko told Ringside that British hopefuls David Price and Tyson Fury are both on his radar.
The world champion has only ever fought one British fighter during his professional career - a comprehensive points win over David Haye last July - but expects one of the country's rising stars to one day challenge him or his brother, Vitali.
He says 28-year-old Price and 24-year-old Fury currently lack the experience to fight at world level, but is tipping at least one of them to step up to the top of the sport.
He said: "I will mention that here in Great Britain you have two fighters that are young and are true heavyweights.
"That's David Price, obviously, and Tyson Fury. I think they're both very talented. I think they will belong, in a certain period of time, at the top. They will become champions at certain times.
"I think they have to gain experience, of course, and I would say that probably one of them is going to end up as an opponent of the Klitshcko brothers.
"It's great. It's always been like that in the history of boxing that young generations change the older generations of boxers.
"I'm not saying we are going to lose, but I'm saying eventually they will come up and will fight for the title and they're obviously going to become, one day, champions."
Wladimir was in the UK to promote the new 'Klitschko' movie, which tells the story of his and his brother's careers in the ring.
But while the film offers a retrospective on two glittering careers, he insists he is preparing for his mandatory fight with Tony Thompson on July 7 and has no plans to hang up his gloves any time soon.
"It makes me feel kind of sad when you say that," he added. "It makes me really upset because I don't feel this way. I can speak for myself, I cannot speak for my brother who is obviously older.
"There is two things that can change; health and motivation, but so far I feel - knock on wood - great. I'm ambitious and hungry for success and my motivation hasn't disappeared yet.
"I'm very, very motivated in what I'm doing, especially when I have so much support from the fans around the world. It gives you so much energy to perform."
