Jack Catterall is pleased with the way his new life in America has started.

It is a less than a month since the 32-year-old from Chorley made the difficult decision to trade Jamie Moore’s gym in Manchester for life under Derek "Bozy" Ennis in Philadelphia.

Catterall (31-2, 13 KOs) is a devoted family man but decided that he needed an entirely new approach ahead of his November 15 welterweight fight with Ekow Essuman (22-1, 8 KOs).

Catterall is a master at controlling the pace, range and tempo of a fight but has attracted criticism for not running though the gears once he has taken a contest by the scruff of the neck.

On his way through the ranks, Catterall was renowned for his predatory instincts and his thudding, accurate counterpunching. He has matured and his style has evolved since those days, but he believes that relocating to Philadelphia will extract something extra from him at a crucial stage of his career.

“I don't think, at 32 years old, you’re going to see a complete different fighter. I think it's going to be more the environment I'm in and the pressure to perform,” he said on Matchroom’s Flash Knockdown show.

“There's a lot of stuff. I'm not going to sit here and dissect each and every training session and what we're doing, maybe that's not a thing that they do over here, but I’m certainly working on things.

“They’re studying previous fights of mine. They've watched me spar over [last] weekend, so I'm getting instructions and I'm getting a lot of good work in the gym.”

That sparring came against his new gym mate, Jaron Ennis (34-0, 30 KOs).

The former unified welterweight champion is just a week away from making his junior middleweight debut against Uisma Lima (14-1, 10 KOs), an Angolan southpaw. DAZN will broadcast the event from Philadelphia’s Wells Fargo Center on October 11.

Catterall’s arrival gave him the chance to get in some work against a high-class southpaw and also allowed "Bozy" to see how his new recruit would fare against his son, one of the best fighters in the world.

“It was difficult, but I held it together,” Catterall said.

“I think it just reiterated the people that I've chosen to come and train with, the respect in that gym. I've come out here off my own back, dropped in a gym with a load of new faces and I think I earned the respect last Saturday.

“I helped him out and did what was asked of me in the ring. I learned a hell of a lot, surrounded myself with new coaches and new fighters. So, I would say up until now it's been a success.”

Earlier in his career, Catterall made numerous trips across the Atlantic and shared the ring with Floyd Mayweather and Canelo Alvarez. Those early sparring sessions gave him a glimpse of what it would take to reach the very top of the sport.

Since then, he has developed into one of the leading junior welterweights in the world and has boxed top-class operators such as Josh Taylor, Regis Prograis and Jorge Linares.

After seeing and feeling what Ennis is capable of, Catterall has no hesitation in putting him in the same bracket as those fighters.

“I think he's a complete fighter,” he said. “Certainly one of the best fighters I have been in the gym with and I’ve been in the gym with a lot of good fighters over the the last 10-15 years. He's right up there.

“The aggressiveness, the defence, the skills, the speed. He’s the full package.”
