Neither have the principles that have made the facility one of the most feted in recent boxing history thanks to the work of Abel Sanchez.

It is now approaching two years since Filip Hrgovic, the Croatian heavyweight contender, joined the long roll call of fighters to have called the place home. He has fought and won three times since, which has set up his first attempt at the world heavyweight title.

Hrgovic faces undefeated 21-year-old "phenom" Moses Itauma, a staggering 8-1 favorite, at The O2 in London for the IBF title vacated by Oleksandr Usyk earlier this year. The 34-year-old has already been widely written off as little more than a footnote in the story of Itauma’s rise to the top, and that narrative has not gone unnoticed up in Big Bear.

“He has a chip on his shoulder because of that,” Sanchez tells The Ring. “He is already one of the most disciplined fighters I’ve ever had, right up there with Gennadiy [Golovkin], but I think the difference between him and Triple-G is that chip on his shoulder.

“He has never gotten the accolades or the respect he deserves, but he has never stopped pushing. He’s from a country with 3.5 million people or something. If he was from the U.S., Mexico or even the UK, he would have got far more opportunities.

"He’s got this chip on his shoulder because he feels he has never had the accolades or respect that he feels he deserves. That manifests in his discipline.”

Discipline is a requisite quality at The Summit, where Sanchez relies on strict, old-school, almost military-style methods to ensure all his fighters are capable of relentless output should they need it.

“I've had the opportunity to work with a lot of young men that gave me the chance to mold them,” he says, "mold them in a style, because if you notice, all my fighters fight in similar ways, and that’s as a result of the system I structured more than 40 years ago.

“Filip does all of that. He still runs the miles, still does the sprints. He still does all the exercises in the gym that you saw Gennadiy do. I've been doing that for 40 years, which goes way back to the Terry Norris days.

“Filip is kind of like the leader in the gym now, and if he's doing it, everybody's trying to run with him. For a coach, it's a great thing.”

In his first two fights after joining Sanchez in Big Bear, Hrgovic showed his ability to go long with back-to-back unanimous decision victories in 10-round fights. But, given the fact that all but two of Itauma’s 12 knockouts have come inside two rounds, the prevailing wisdom is that Hrgovic will look to take Saturday’s fight into the later rounds and then attempt to take over.

“That’s not necessarily how I see it,” Sanchez says. “I think Filip will take Moses somewhere he has never been before, but that could be in the second or third round. He's in there with a bigger man, a big, taller man that's got the experience to be able to do damage to him that nobody else has been able to do.”

Indeed, over the course of Itauma’s 31 professional rounds to date, nobody has managed to land a meaningful shot, much less put him in any trouble. Should he win the title on Saturday night, Itauma will become history’s second youngest world heavyweight champion and Britain’s youngest world champion at any weight.

“What is it they say?” Sanchez asks, without waiting for the answer. “Youth is wasted on the young. If you look at a lot of sports, not just boxing, when does it actually work out for these young phenoms?

“It's not the boxing career part of it; it's the private life more than the boxing part of it. ... Mike Tyson was successful for a long, long time, but his personal life was falling apart. Same thing like a lot of these guys that all of a sudden come up really hyped and something falls apart. Maybe they lose because of the outside life.

“I don't want to see that for [Itauma], of course. I want him to have a great, successful career win, lose, or draw this fight. But for me it just feels like Filip has arrived at a place where he is ready to win the world title.”

The same for Sanchez, now 77, who would tick off one of the last remaining boxes on his list of career achievements should he steer Hrgovic to victory.

“I’ve never had a heavyweight champion, so that would be a big thing,” he says with a smile. “Winning it would be like the crowning achievement in my career because everybody feels like the heavyweights ... are the special ones.

“Triple-G’s record is something that is very special to me, Terry Norris beating Ray Leonard is very special to me, but to have the world heavyweight champion would be something special too. Victory on Saturday would sit alongside all of that.”
