FIRED-UP Denise Castle insists she has the capability to end Momo Koseki’s dominance of atomweight boxing ahead of Saturday’s showdown in Tokyo.

The 42-year-old East Cliff puncher will hope to complete the fastest-ever route to a world title when she takes on the 14-time champion in her own back yard.

Previously a global champ in muaythai, Castle has been fast-tracked up the boxing ladder since taking up the sport earlier this year.

She beat two Thai opponents in April, which was enough to convince the World Boxing Council (WBC) that she was worthy of a shot at Japan’s Koseki.

And following a punishing 10-week training camp, the mum-of- two believes she is ready to defeat the Far East legend, who is unbeaten in seven years.

Castle told the Daily Echo: “I’m feeling probably the best I’ve felt in a long time. I’ve really got the hunger for it.

“I really want to win and I think that’s a key part. I’m going to go for it from the bell, I’m not going to wait.

“I have had a lot of support which has really helped. It has really carried me along and given me belief, and I just really don’t want to disappoint people.

“I want to bring the title back and in fact, I will be really disappointed if I don’t. One of the reasons I want it so much is that I know I’m capable of it.

“I’m not the favourite to win but in my eyes I have the ability to do it. I’m just going to go in and give it my all.”

Trained by her husband Lorne, the diminutive but powerful Castle has put in long hours of training for a fight that she has labelled as the biggest of her life.

And Lorne has backed his partner to get the better of her southpaw opponent, who has a record of 18 wins, two losses and one draw.

He said: “Denise has had one of the best training camps we’ve ever done. Physically, she’s the strongest she’s ever been.

“Pound-for-pound, I don’t think Momo would have faced as hard a hitter as Denise, so that’s in our favour.

“Denise’s best fights in muaythai were when she hit hard and went forward. She had pure aggression and that’s what we have to do on the day.”
