Anthony Joshua admits he studies unified world lightweight champion Katie Taylor due how refined her skill and technique are.
The world heavyweight champion is close with his fellow Matchroom stablemate, who is also pursuing the undisputed champion at her weight class.
The Irishwoman can add another world title by defeat Rose Volante in Philelphia on Friday, with Joshua impressed by Taylor's preparation.
"When I watch her, I learn from her as well," Joshua told Sky Sports.
"Even as a champion, I watch her and think I need to do something like that. She has her skills and technique down to a tee.
"I think for Katie and anyone who is fighting, it's just important to be yourself. She's definitely going to become undisputed champ.
"She's very calming, which is working for her, she's a beast in the ring, and just keep on doing what you're doing.
"Some people talk a good game on the outside, but they don't fight like it on the inside."
