Audley Harrison's trainer believes his charge is fully motivated ahead of the make-or-break domestic match with Matt Skelton in London on 9 December.
Harrison won gold at the 2000 Sydney Olympics
Thel Torrence is back in the London heavyweight's corner having been sacked after Harrison's dismal losses to Danny Williams and American Dominick Guinn.
"Audley's psychologically right for this fight," Torrence told BBC Sport.
"His attitude's right, his eyes are open, he's motivated and he's learning new things. Our heads are together."
Torrence added: "He's back to where he was when I first started working with him, and that's what motivated me.
"I've got to have 100% of a fighter's co-operation - if he's motivated, I'm motivated."
Harrison dismissed Torrence after being outpointed by Guinn in April, asserting that he was spending too much time with then world heavyweight champion Hasim Rahman.
Boxing's not a street fight, it's about skill and technique
Prior to that encounter, Harrison was booed from the ring after dropping a split decision to fellow Londoner Williams last December.
He hired top trainer Buddy McGirt for his comeback win against Andrew Greeley, but now insists Torrence is the right man to deliver him a world title.
"I decided I needed to prepare for this fight at Big Bear [boxing camp, California], because that's where I've had my best camp," said Harrison.
"Buddy McGirt was unable to come there as he's set up at Vero Beach [Florida].
"There's never been any animosity between me and Thell. He's a world-class trainer and he's good enough to get the job done."
As for Skelton, Harrison reckons he will have too much boxing ability for the Bedford brawler in their Commonwealth title clash.
"Matt Skelton is a tough guy and comes into the ring with a lot of spirit," said Harrison.
"He's going to come forward, throw a lot of punches and try and rough me up, so it's about using my skills and technique.
"Boxing's not a street fight, it's about skill and technique. I'm a boxer, an Olympic gold medallist, and that's who's turning up on the night."
