Tyson Fury insists he can be even better than the boxer who destroyed Deontay Wilder in their heavyweight title fight.
The Briton, 31, dominated from the opening bell until Wilder's corner finally called a halt to proceedings in the seventh round with American looking in danger of being seriously hurt having been put down twice already in the bout.
Fury had promised to go for the knockout before the fight and made good on that with a performance at odds with his usual approach of fighting on the outside.
With the WBC title secured and his pick of lucrative fights against either Anthony Joshua or another rematch with Wilder to follow, Fury says that working with SugarHill Steward is going to turn him into an even more accomplished fighter.
"I'm my own worst critic and even though it was a fantastic performance and I got a great win, I know I can do better," Fury said.
"I've only just started with my new trainer, SugarHill Steward. We only had seven weeks to perfect a Kronk Gym style. But I'm a quick learner and I aim to get back to the gym straightaway, to work on balance and straight punches."
Wilder, who had dispatched 41 of his previous 43 opponents by way of knockout, had mocked Fury's power in the build-up to the Las Vegas showdown, saying the Englishman had "pillow fists".
That theory soon went out the window at the MGM Grand Garden though with Fury flooring Wilder with a right hand in the third and a left hook to the body in the fifth.
Blood poured from Wilder's left ear and he was taken to hospital after the fight ended.
"I'm going to be putting people to sleep left, right and centre," Fury said. "Don't forget when I came here people said I can't punch. Wilder himself said I've got 'pillow fists' in the past.
"Well it didn't do badly for an old fat guy who can't punch, did I?"
Victory over Wilder was the 21st stoppage for Fury in 31 fights. Asked whether he believes he is the biggest puncher in the heavyweight division, Fury said: "No ... I'm an old feather duster who can't break an egg, aren't I?
"With this weight and technique we can knock out anybody. When I jumped on the scales people thought I hadn't come for a fight, that I'd underestimated Wilder, come for a payday. When I got in there I felt like a beast. This is my weight."
Fury has now held all of the major world titles in the division, having outclassed Wladimir Klitschko in 2015 to win the WBA, WBO and IBF belts before spiralling into a spell of depression and inactivity that saw him stripped of his titles.
Fury - who socialised with fans in Vegas in the wake of his win - still believes a third match with Wilder could happen, while Joshua's promoter Eddie Hearn is pushing hard for a unification bout - Joshua holds the WBA, IBF, WBO and IBO belts - with his client later this year, with Saudi Arabia emerging as a potential venue.
For Fury's dad, John, who was not part of his entourage in Nevada for the Wilder victory because of visa issues, retirement should be an option for his son.
"I want my son to retire now, that's just my opinion. He's done enough, he's got no more to prove. He's proved he's been a worthy champion from this country. He's been 13 years as a pro and he's always been the opponent, wherever he's gone to, it's been an uphill battle for him," he told Good Morning Britain.
"He's got a young family, and I do believe his children deserve a father - and he's done enough. That's my opinion. I want him to pack it in now, I've said that to him."
