It is Monday afternoon and the towering duo of Ismet and Endrit Ademi are sitting side by side in front of a mobile phone.

The brothers are speaking to The Ring via Zoom and have to squeeze in next to each other so they are both visible in the frame. Without thinking, 24-year-old Ismet drapes his arm around his younger brother Endrit, 21, so they can fit in the shot.

Earlier this month, it was announced they have both signed “multi-fight, multi-year” agreements with Ringside Zone after flawless starts to their lives as professional fighters. Young Endrit is 2-0 with two KOs while Ismet is 1-0, with his debut ending inside 110 seconds.

The brothers from Aachen, Germany were the subject of interest from promoters across Europe and America but decided on Ringside Zone in a bid to build their legacy from the ground up in their home country rather than chance their hand abroad at this stage.

And it is a good time to be doing so, given that one of the four world heavyweight champions, Agit Kabayel, is also from Germany. In fact, in Kabayel, Filip Hrgovic, Daniel Dubois and Murat Gassiev, the heavyweight division has a very European flavor as it stands.

An obvious interview question for hot prospects is one about what they hope to achieve in a sport which they are about to dedicate another 10 or 15 years to. The answer is often very similar but these two have little doubt that they are heading right to the very top.

“We know we will take all the belts at heavyweight,” says Endrit, who does most of the talking for the pair. “We know this already so this is not a question for us.

“But first of all, we want to ensure we have our health, I hope, because this is the most important thing. I would not be happy to have the world title but my brother is in the hospital and he’s not in good health. That is the most important thing for us.”

It is one of many examples of their close bond throughout the interview. They do not have any other siblings and were both introduced to boxing by their father, who decided the best course of action was to hang a heavy bag in the middle of their bedroom. “I would wake up,” Endrit says. “And the first thing I’d see is a boxing bag.”

He was just five years old at the time while Ismet was seven. Their father, Lavdim, decided it would be best if his two boys learned how to defend themselves early on. It worked.

“We were just like the other kids,” Endrit says. “We would go out and play and whatever but my father would be at the window saying ‘hey, come in and train.’

“So from an early age we had to train, we had to be like men.”

It would be the start of their journey toward much amateur success, which spanned around 80 bouts combined. Ismet claimed three national titles while Endrit won four as well as a medal at the European games.

The younger brother would also cross paths with Itauma as an amateur and became one of the few men to last the distance with the southpaw phenom. “That was the year when he became European Championships by stopping all of his opponents in the first round,” he says.

“But after our fight went the distance, the whole team came over to me and asked who I was because I’m a great fighter. I just told them ‘hey, I’m a great fighter too!’

“My brother also sparred him so we know all about him now. I know when the time comes I will repeat this story with Itauma but it will have a different ending. In my country, we don’t like unfinished business.”

The Klitschko comparison is an easy one for Florian Winter, the founder of Ringside Zone, to make, but the Germany-based Ukrainians have long been an inspiration to the Ademis. Wladimir and Vitali, who won multiple world titles between them, were both dominant champions but with very different styles. Vitali, the elder of the two, was more unorthodox while Wladimir built most of his success behind long, straight punches.

And, while the Ademis were both brought up on the same videos put on by their father, they have also developed very different styles. “I am more of a blend of styles,” Endrit says. “A more technical fighter who spots what my opponent is doing wrong.

“But for me, I love Mike Tyson,” Ismet cuts in. “I like knockout fighters, I just love knockouts. I’m a puncher who wants to knock you out and get out of the ring.”

Between July 2011 and December 2013, the Klitschko brothers had a complete stranglehold on the division as Wladimir held WBA, IBF and WBO belts while Vitali had the WBC. No two brothers had done that before and none have since.

The question that followed them throughout that period was whether they would ever fight each other in order to crown an undisputed heavyweight king. The pair, of course, refused.

“Look, I don’t even like pushing him for a joke,” Ismet says. “He is my little brother, how could I punch him in the face? We have never ever even sparred, my mother would fight us for this.

“We just push each other every day and that won’t stop until we reach the top.”

Alongside them every step of the way will be Lavdim, who inspired them to box by hanging that bag in their bedroom and inspiring them to study the greats on film.

“My father and the whole family support us every step of the way,” Endrit says.

“On one hand this is pressure for us, but on the other it’s motivation because we know we don’t have any other way. It’s boxing or nothing for us.”
