Craig Cunningham has warned Anthony Ogogo he is facing the toughest fight of his professional career on Saturday night.
Cunningham, who won the boxer of the year award at the Midlands Boxing Awards last week, challenges Ogogo for the WBC international middleweight title at the Barclaycard Arena in Birmingham, live on Sky Sports.
Ogogo (11-0 KO7) has never tasted defeat in the professional ranks, but Cunningham (16-1 KO3) insists he has the punch power to trouble the 27-year-old and believes he will pick up a surprise knockout victory.
"This is a huge opportunity for me," Cunningham said. "They might think this is an easy night for them, that all they've got to do is turn up to win the belt.
"It's down to me to prove otherwise. I've had my small hall brawls, now this is something I can really sink my teeth into.
"I don't care about his record and his past achievements, to be honest, and he can't bring that into the ring with him.
"He's got pedigree but this is the pro game now, it's totally different. It's going to be a hard, hard night for him I can promise him that. I'm going to be his toughest fight as a pro and I am a massive underdog so I have got nothing to lose.
"You are going to see a different Craig Cunningham - I'm going to take it to him, get in there and look for the KO. I think I can knock him out because he hasn't been hit by anybody like me.
"The belt is coming home with me, I've had a great camp and I just want to get my hands on him and show everyone what I can do."
