Andre Ward says he has heard enough talk and wants to get down to the business of proving he is the best pound-for-pound fighter on the planet.
The American will challenge Sergey Kovalev for his WBO, WBA Super and IBF titles in Las Vegas on Saturday night and many experts think the winner will be entitled to claim they are the pound-for-pound king.
Both fighters are unbeaten and their bout will be one of the most eagerly awaited fights of recent years.
And Ward says that, while he is enjoying the trash talk coming from the Russian's camp, he is focused on delivering a tour de force in the ring.
"It's interesting that the ones who are not getting in that ring are the ones that are doing the most talking," said Ward at Thursday's news conference.
"They are not feeling those punches.
"That [the talk] is what a big fight is all about, we are not supposed to like each other. His side has been doing a lot of talking and that's fine, we love it, it's not our first rodeo.
"We don't always respond right away and sometimes our silence is misinterpreted as we don't understand or we don't get it.
"We get it, we watch, we take notes but, in the meantime we keep working, and then we produce come fight night, that is what we specialise in.
"All the talking is great, I love it but, know one thing, I am not taking no mess come Saturday night."
Kovalev says the nerves are jangling a little ahead of such a huge fight but regards that as normal.
"If you are never nervous, it is not good," he said.
"I am in the best shape right now for this fight.
"This fight is a great opportunity for both of us to show the boxing world who is the best pound-for-pound.
"It's going to be a war between us."
Ward is adamant that the bout will be more than just a clash between his renowned elusiveness and the fearsome raw power of Kovalev.
"I have never won big fights just doing one thing, being one-dimensional," said Ward.
"I typically do the opposite of what people think I am going to do.
"We have a game plan and the bottom line is making the necessary adjustments. You have to be able to adjust on the fly and that is what the great ones do."
