"I'm a natural lefty, so yes, he will keep an eye on my left uppercut," Bute told a conference call Thursday in advance of the fight on May 26. "But he should also pay attention to my right hook. For sure, I'll surprise him."
Bute (30-0) is putting the belt he won in 2007 on the line. He's defended it nine times in Froch's hometown of Nottingham to face the brawling Englishman (28-2) before a hostile crowd.
The native of Romania, who became a Canadian citizen this year, wants to leave no doubt he can beat a tough contender far away from Montreal or Quebec City, where most of his bouts are held.
Bute has been training in Britain since last weekend and said he's getting used to the time change and his new environment.
Froch didn't shy away from trash-talking his opponent during the call as he acknowledged his close loss to Andre Ward in the Super Six final on Dec. 17.
"I don't think he's as good as Ward and I'm not sure he's as good as (Mikkel) Kessler or Andre Dirrell or Jermain Taylor."
Froch has downed Dirrel and Taylor and lost by a unanimous decision against Kessler. He said Bute's record only had two names that stood out — Glen Johnson and Brian Magee.
"I'm confident, I'm switched on, I'm not licking my wounds," he said. "I'm not feeling sorry for myself because I lost my last fight. I'm really not. I'm taking confidence from that loss. I know what I need to do to put it right."
He added he's not saying that Bute's not a good boxer, just that that question will be answered in 10 days when the duo face off.
Bute countered it's not the first time he's heard stuff like that from Froch and said he'll have his answer when they trade punches.
