Anthony Joshua is ready to raise his level when he faces Eric Molina in the second defence of his IBF world heavyweight title next month.
The Brit will face the veteran at the Manchester Arena on December 10 and will be looking to extend his undefeated streak to 18 fights.
"We're competing for a championship belt so everyone ups their levels by 50-60 per cent," the 27-year-old told.
"The people I've seen time and time again are not the people I am going to face. So I have to put [Wladimir] Klitschko or David Price or whoever was in the pecking order aside, and focus on what is in front of me.
"When I look at it, I thought he was the toughest out of the few so that's a good challenge for myself. That's the one I have to focus on. I always knew I was going to have someone who was game."
Meanwhile, Molina, who is coming off a win over Tomasz Adamek to win the vacant IBF inter-continental title, is confident his experience will pull him through against the talented Joshua.
"I've been in these fights before, you know what I mean?" said the 34-year-old.
"I have no amateur experience but I'm learning on the job. Look at the job I've been doing, and it's been getting better in every fight.
"I'll fight with everything I've got – if I'm hurt, if I'm conscious, I'm coming to fight. I can win the fight with one punch at any given moment."
