Ben Whittaker faced Liam Cameron at the final press conference ahead of their rematch this Sunday, live on Sky Sports.
Cameron has looked to torment Whittaker since they controversially drew after falling out of the ring in their first fight.
But Whittaker warned him: "I believe that was the best chance to get me and he didn't. Now Sunday it's all fresh and it's all new, so we'll see.

The Olympic silver medallist has brought in a new trainer, Andy Lee, for the rematch with Cameron.
"I've got structure and it's been a great camp. He's a great person to be around. I'm picking up things and learning things," Whittaker said.
The build up to the fight has been overshadowed by an argument over whether the contest would be a 10 or 12-rounder, a dispute which was only resolved on Wednesday.
It will be 10 rounds.
"Last night I got told it was eight!" Whittaker joked, but he added: "We've done many rounds and we'll see."
Cameron still criticised him.
"They paid me an absolute fortune," Cameron declared. "He could have called my bluff. I could have been wanting to do the 10 all this time."

He insisted he was relishing the drama of his rematch with Whittaker and headlining a big arena show.
"I dreamed for these moments. How can I complain? I'm here, I'm ready, I'm in much better shape [than the first fight]. Let the games begin in the ring now," Cameron said.
"I've given myself the best opportunity," he added. "I've put myself in a frame of mind, a mental state, where I'll be scared. I'll be that scared dog in the changing room and that brings the best out of me.
"It's been magical and we're going to put on a big show."

Olympic bronze medallist Frazer Clarke suffered a heavy first-round knockout defeat in his rematch with Fabio Wardley last October and the Burton heavyweight returns at the bp pulse LIVE arena against Ghana's Ebenezer Tetteh, coming off a hard-fought loss to Dillian Whyte.
"I'm here to do what I know I can do," Clarke said. "I have to concentrate on Sunday, going out there and performing.
"There probably is question marks [about me] from weak people, people who aren't really fighters or made of the right stuff. There's no question marks from me. I've been hit before. I've been injured before.
"I'm made of the right stuff. I just want to put a show on and show people there's more to come."

"They will know why they say I'm the next big thing."
Denny was nonplussed. "I've got a good dancing partner," he said. "He is a threat he's going to be game but he's going to be dancing to my song in there.
"I'm going to punch him up the same way. It makes no difference."
