Katie Taylor has said it feels "absolutely incredible" to be crowned the undisputed lightweight champion of the world.

The Bray boxer was speaking after defeating Belgium’s Delfine Persoon last night at New York’s Madison Square Garden. 

"This is what I’ve dreamed of since turning pro," she said.

"This was always my ultimate goal. To have all five belts and to make history in my sport, this is what it’s all about."

"This is why I sacrifice so much, why I train so hard," she said.

It was a tough fight for Katie and she won by the narrowest of margins.

Her opponent stormed out of the arena when the result was announced, clearly annoyed at the judges’ decision. 

The close call has led to speculation about a rematch something which Katie Taylor says she’d be open to but added that she has other fights planned.

"Ye definitely, were definitely very open to a rematch, we’ll see what happens down the line. There’s a lot of big fights out there for me, so I guess we can talk about that later on," she said.

She said she knew the fight against Delfine Persoon would be tough and that it was very close. 

Katie praised her opponent, describing her as a great champion. 

"I knew it was going to be a very very tough fight. It was exactly how I see it really, it was a very close fight but we knew we stole some of the earlier rounds and we knew we definitely won the fight"

"Persoon has been a great champion she’s been a long reigning champion for a long time.

"But that’s what happens when a champion is in against another champion, it’s the best against the best," she said.

She added: "It was a genuine 50/50 fight and we saw that tonight".
