Katie Taylor has told her rivals they have "a responsibility as professional fighters to fight the best" as she looks to scale every possible height in 2019.

The Bray lightweight world champions was supreme last weekend as she outclassed Eva Wahlstrom at the iconic Madison Square Garden on the undercard of Canelo Alvarez's world title fight with Rocky Fielding.

Taylor is 12-0 in the paid ranks, and already has the WBA and IBF straps safely secured, joining Ryan Burnett and Carl Frampton as the third Irish boxer to accomplish the feat of unifying her division.

She has had Brazil's WBO world champ Rose Volante and the WBC belt holder Delfine Persoon on her radar for months in a quest to become the undisputed champion of the world but has been left frustrated as a showdown with either has failed to materialise.

Speaking to RTÉ Sport's Evanne Ní Chuilinn, Taylor was forthright about her desire to hunt down the two incumbents.

"Eva came to win, to give her best, which got the best out of me I think," she said of last Saturday's win in New York.

"To have the chance to fight at Madison Square Garden, the most iconic arena in the world, it was an absolutely incredible experience.

"A couple of years ago, after the Rio Olympics, I never thought I'd be in this situation, where I'm actually boxing in these stadiums.

"I was on the Canelo undercard as well, one of the biggest fighters in the world right now. I think I got all the Mexicans on my side by the end of the night! 

"I'd say I get frustrated by girls not taking the fights more than anything else. The fights are definitely out there for me but they have to step up the plate and actually fight as well.

"To call themselves world champions, they have to fight the best. It's their responsibility as professional fighters to fight the best.

"[Rose] Valente has a WBO belt and Delfine Persoon has a WBC belt. The only fights that really make sense for me is one of them next. I want to become the undisputed champion.

"Why not make those fights happen? It's great for the sport, it's great for women's boxing. They are the fights everyone wants to see."

What's more likely is a meeting with Puerto Rican Amanda Serrano, who is one of just three boxers to win titles in six weight divisions. Oscar de la Hoya and Manny Pacquiao are the others.

In October, Taylor retained her WBA and IBF belts with a convincing defeat of Amanda's sister Cindy Serrano. 

"I think the fight with Amanda Serrano [above] is the biggest fight in women's boxing at the moment," added Taylor.

"That's huge. That fight is going to happen some time next year. She is signed up with Eddie Hearn now as well so that fight is very easy to make. 

"When I first sat down with Eddie that was my plan all along to have three or four fights every year. The fights are getting bigger and bigger. The tests are getting tougher and tougher. It's going to be an exciting year."

The 2012 Olympic gold medallist has achieved so much in the game but still her to-do list is lengthy.

A homecoming fight would be "a dream", with glory her only driving force.

"A huge fight in Dublin would be a dream. I hope that can happen some time soon.

"Money doesn't motivate me at all. The moment money is my motivation, that's a dangerous thing. I find it a distraction more than a motivation. I just want to fight the best. I want to make history in the sport. I want to leave a great legacy behind me. That's all I'm targeting. 

"I want to be the best I can. I want to be the best of all time."
