The elder brother of Wladimir Klitschko ex-world heavyweight champion Vitali Klitschko is confident that his younger brother will be able to regain titles and win Joshua by knockout.

"The fight will be very exciting for the whole world of boxing. Two Olympic Champions. One of them is older than the other, but I saw my brother in training. Nobody's perfect. Each has its own strengths and weaknesses. My brother's weakness is concentration. Vladimir was not 100 percent concentrated in the fight with Fury. That's why he lost.

He knows that now he is ready for this fight very well. I've never seen my brother so focused during preparation.

And I know that Vladimir has an excellent technique, perfect condition, high speed and, what is most important in life and in sports, a lot of experience and a great championship experience. If Vladimir will be concentrated in the fight, Joshua will not have any chance. I'm more than confident that Vladimir knocked out Joshua for ten rounds, "- said Vladimir.

Recall, April 29 at the London arena, "Wembley" will fight Klitschko junior with the British Anthony Joshua.

At stake will be the champion titles WBA Super, IBO and IBF.
