Anthony Joshua insisted he would cherish the memories of his remarkable defeat of Wladimir Klitschko - but that victory did not top winning his Olympic gold medal.

The 27-year-old added the WBA, IBO heavyweight titles to his IBF belt after recovering from the first knockdown of his career to eventually stop Klitschko in 11 rounds at Wembley Stadium.

In only his 19th professional fight Joshua also established himself as the world's leading heavyweight, overcame one of the finest in history and fought in front of a post-war record British boxing crowd of 90,000.

However, despite also revealing the exhaustion he had to overcome to win such a defining and entertaining fight, he insisted it did not represent his peak.

"The memories, the experiences last forever, and when it's all said and done these things (the belts) slowly disappear," Joshua said.

"The experience I've gained is more important than the belts.

"Sugar Ray Leonard: all the skill, ability he had, said there are times when you have to show character and go to the trenches. Without that you'll never go on and do great things in the sport.

"I never want to be in those type of fights, but if I have to be I don't want to crumble."

Asked if it topped winning Olympic gold, he said: "No. It is what it is: there's one winner and one loser.

"I'm a champion outside the ring, first and foremost. The fighting is fun. I don't box just for the belt, for the money, and I just enjoy it, the discipline.

"How am I feeling at the minute? Like I did before I won this fight. I'm happy, if anything, that it was a great fight, because there was a lot of hype, a lot of attention around the fight, and I'm glad it lived up to expectations; that's it.

"I'm going to pop round to my family's house. I want to catch up with family and go back to normal living.

"(I learnt) that I can knock out anyone. If I can keep on improving on the things I do well, I can definitely knock out any opponent.

"To get knocked down, hurt someone, get hurt, take someone out in the championship rounds where I've never been before, it's testament to what training's about."
