This has been a dream of mine since I was a kid... I'm passionate about being a world champion, believe me.

I'm actually a mummy's boy.

I've gone from the top of the world to the bottom of the ocean.

If I can't beat DeLuca, how can I say I want to fight the elite of the sport, rematch Errol Spence or fight Terence Crawford? There's no point and I don't have the right to call for world titles. No - I have to win.

I've got all the attributes. I've got the sharpness. I've got everything you need to be a top fighter.

I saw Bob Arum out in America, I saw him walking through the lobby in the MGM Grand. I basically went over and said: 'You're running out of opponents for Crawford and I'm the guy to beat him. I'm here.' I saw Terence Crawford, he said he was ready for it, so everybody is on the same page. Everyone wants to make the fight.

Looking out the window and seeing the MGM and Floyd Mayweather takes me back to when I was a kid. Those were the places you'd hear about, the ones that staged big fights and top fighters. You always want to one day fight there yourself.

It's depression. You can't put it into words. You get stuck and time passes by. I'm stood there on the edge of a cliff, can't go back and can't go forward. Days go by. I'm still in the same place. Everyone else's life goes on, but you're stuck. You try and try and try and I don't know how, but you came out of it eventually.

Small things make me smile.

It is frustrating, but all I can do is just keep winning, and hopefully, people will stand up and take notice eventually.

I never went through an easy fight. Every fight has been hard fought.

I would have loved to have met Roger Federer.

It's great for my confidence getting a letter saying 'All I want from life, Katie, is you and health.'

Don't call me famous, but it's hard to be out with my friends now.

Going to the cinema or a meal can be difficult, with people asking for pictures or autographs.

It's important to have a healthy balanced diet but not to get too bogged down about it. It's important to enjoy your food, too.

I can enjoy myself and express myself in the ring.

I always come into these competitions hoping to come away with a gold medal. I won't relax until I have the gold medal around my neck.

After I came back from London with a gold medal, my focus straight away was to defend it four years on.

It's so great to be able to inspire these young women today to get involved in male-dominated subjects.

Anything other than a gold medal will be disappointing.

Mental strength is something you either have or you haven't.

I do a good job of staying positive and just moving on.

It's such a shame, really, because we were known for our country of saints and scholars, and we grew up with such a great tradition with St. Patrick, and he is the one who brought Christianity to Ireland, and we celebrate St. Patrick's day every single year, but there's very few practising Catholics or practising Christians.
