Katie Taylor enjoyed unparalleled success as an amateur boxer, winning five world championships, as well as securing the Olympic gold medal at the London Games in 2012.

Since moving into the professional ranks, the Irish boxing sensation has gone 20 fights undefeated, en route to becoming the undisputed lightweight champion of the world.

And yet, ahead of the biggest women's boxing match in history of the sport, as Taylor takes on Amanda Serrano at Madison Square Garden, the Bray native is convinced that she would not have made it this far had it not been for the disappointment of the 2016 Olympics in Brazil.

Champion at the inaugural event in 2012, where women’s boxing was introduced for the very first time, Taylor set about defending her title in Rio four years later.

But Katie would come unstuck at the first hurdle in Brazil, resulting in an illustrious amateur career coming to a close in very unfamiliar circumstances.

Taylor would attempt to put the disappointment of Rio out of her mind as she embarked on a professional career in the sport, working alongside renowned promoter Eddie Hearn.

Twenty fights later and four world title belts in her possession, Taylor is now the talk of the sporting world this weekend, as she puts her undisputed title on the line against Puerto Rican New Yorker Serrano.

But for Taylor, she looks back on that disappointing Olympic campaign in 2016 and is convinced that the disappointment of the quarter-final defeat to Mira Potkonen had led her on the path to glory in the professional ranks

"There definitely is," said Katie, when asked whether she felt that Saturday’s fight somewhat mirrors the gold medal fight in 2012.

"Obviously the biggest moment of my amateur career was the Olympic gold in London and now here I am as a pro, involved in the biggest fight of my career on Saturday night about to make history again."

Saturday’s fight also brings an Olympic element to the contest as the biggest fight in Taylor’s professional career mirrors that road to London glory in many ways.

Taylor has almost singlehandedly pushed women’s professional boxing into the mainstream over the past five years, and it was the same in the amateur ranks as she first brought women’s boxing into the public’s imagination, before doing the difficult task of convincing the IOC to include the sport in the 2012 Games.

"I definitely would not be here right now if I had of won gold in Rio," said Katie. "It's amazing how it all turned out really.

"My biggest disappointment in Rio has turned out to be the springboard to my greatest comeback, I guess.

"And that’s an amazing thing, the huge setback that I had has put me in this position. I never thought that I would be in this position, headlining Madison Square Garden.

"I experienced both at the Olympic Games, the highs and the lows, and I’m definitely very grateful that I’m in this position now and I was able to come back from that huge disappointment."

As for the fight, Katie appears relaxed and ready to shine once again on the biggest stage, and while the similarities to the London gold medal bout exist, the champion admitted that she is glad that she does not feel the same pressure that came with that London experience where she felt she was carrying the expectation of the entire country.

"I don’t think anything can compare to the pressure I was feeling going into the London Olympics," said Katie, when asked whether she felt extra pressure coming into the New York fight.

"My whole childhood was based around this Olympic dream and I felt like the whole weight of a nation was on my shoulders during that competition.

"So this seems like a piece of cake in comparison to the pressure I was feeling at the London Olympics to be quite honest."
