Anthony Joshua says that the sparring he did in training was vital for him to overcome Wladimir Klitschko in their heavyweight clash last April.
Joshua admits that he felt he had Klitschko beaten as early as the fifth round, saying that there was a specific way of knocking someone down that he didn't do.
"I have watched the fight. It's still entertaining. It was interesting", Joshua told ESPN, "I thought I had won in the fifth.
"That is the worst thing. There is a way you can knock someone out when they are hurt. All you have to do is trap them and just tap one here, tap one there. At the time I was hitting him with big right hands, you know what I mean?"
The 28-year-old then goes on to explain how important sparring was for him, having gone into training heavy and working 15-rounds to ensure he was in the best possible condition.
He added: "The best thing I could have done is I came in a bit heavy for the training camp. Rob knew. So in sparring, we were doing 15 rounds sparring and it's not like it was a slow pace. I am sparring with amateurs, sparring with pros.
"They [his sparring partners] are rotating. They are coming in fresh. Honestly in the spars, probably at round seven or eight, or round nine, eight, nine, ten I was tired in the spar and I would take a bit of time off. I would take a few.
"What I learned in the spars there is how to survive in tough times when I am tired and I still have 'X' amount of rounds left. We are not doing 12 rounds, we are doing 15 rounds.
"That is what got me through -- the tough times in training got me through that tough time in the fight. I just knew how to survive in dangerous times.
"When it got to round nine, and Rob was like 'there are only a few more rounds left', I knew that is when I would have my last three or four rounds in my 15 round spar. When the next sparring partner comes in and does his four rounds, I know I can batter him in them four rounds because I have got my energy back after that rest. I knew. I just reflected back to training camp."
With Klitschko retired and Tyson Fury not able to compete, Joshua's most anticipated potential fight remains a unification clash with American Deontay Wilder.
Wilder, the WBC Heavyweight Champion, has made no secret of his desire for a highly lucrative fight with Joshua - and the Briton was more than happy to tease it.
"You know what, you have to be careful of the quiet ones. That is why I am not going to say much. This is why this fight with Takam is important because it does set up the questions for next year. What is he [Wilder] going to do? Imagine if that fight did come off in 2018..."
