“He was saying how obsessed he was with becoming heavyweight champion of the world again," said Joshua."If you fail at the first hurdle, you go again - [he] knew from my side I was ready for a rematch, making it clear that if he wants to go again, we'll go again. With Klitschko, we weren't hearing too much, so I just thought he was 50-50, but I had a feeling he might not fight again."
When asked how much of a disappointment Klitschko's retirement was, Joshua replied: "Massive. It was probably even a disappointment for his management, his trainer."
Wladimir Klichko is a two-time world heavyweight champion, who has held the WBA (Super), IBF and WBO titles, as well as the IBO, Ring magazine, and lineal titles. Klitschko is considered to be one of the greatest heavyweight champions of all time.
The boxer announced the end of his career, at the age of 41.
