Caroline Dubois splits from trainer Shane McGuigan ahead of lightweight title defence vs Amelia Moore

Caroline Dubois has parted ways with trainer Shane McGuigan before she bids to defend her WBC and WBO lightweight titles against Amelia Moore in Birmingham on August 29, live on Sky Sports.

McGuigan, who has established himself as one of the world's best boxing trainers, began working with Dubois in 2021.

Together, the pair have enjoyed some great success, with McGuigan guiding Dubois to victories over Maira Moneo, Bo Mi Re Shin, and the 25-year-old's title-unifying victory against Terri Harper in April.

In 2023, McGuigan backed Dubois to "capture all of the belts", adding "she is the best lightweight in the world".

"Even though the lightweight division is probably the most highly contested division in female boxing, she's blitzing everybody," he told Sky Sports.

McGuigan also said he expected the 25-year-old to become an undisputed champion across multiple weight classes.

"I genuinely believe she can do it at lightweight, super-lightweight and welterweight. She's still developing. She's getting much better all the time."

Scotney: Sometimes you have to make a change

Former undisputed world champion Ellie Scotney told Sky Sports:

"Caroline is a generational talent and I think she's just scratching the surface.

"It's one of those where she has to follow if there's something new that she wants to align.

"Nothing was going wrong for her to make that move. But sometimes you just have to make a change, and I think she's at that place."

Dubois wants more belts

Dubois and Moore will fight at 135lbs over 10 two-minute rounds at the bp pulse LIVE Arena, with Mikaela Mayer and Chantelle Cameron set to headline the event, which is entirely composed of bouts between UK and USA female fighters.

But the English fighter is "frustrated" by having to defend her titles, rather than unify the belts. She had sought out a fight to challenge IBF lightweight champion Elif Nur Turhan, but was left disappointed when her team's proposals were pushed back.

"From what I hear and from what my promotions are telling me and my team is telling me, they made her [Turhan] an offer and she asked for such an astronomical, ridiculous amount. It was absurd. It was crazy," Dubois said.

"The amount she asked for, it wasn't even a laugh out of the room. It was just so ridiculous.

"She isn't about it. She thinks that she is something that she isn't and I'm really disappointed in her and how she's moving because it's all good to talk online. She asked for the most ridiculous number that, even if I told you, you would think I'm lying.

"So she just isn't about it. She's a joker and what you do with jokers, you just leave them alone. That's retirement money. That's never-fight-again type of money."

Dubois believes the fight with Turhan will happen eventually but is also eyeing up a meeting with WBA lightweight title holder Stephanie Han.

Earlier this year, the British fighter also called out Alycia Baumgardner, saying their much-anticipated bout "has to happen sooner rather than later".

"She's got no opponents," Dubois said. "She wanted the Katie Taylor fight, but that's not happening. She wanted the Amanda Serrano fight, but that's not happening, so who's she going to fight? Absolutely nobody.

"There's no one she can step into the ring with that's on my level. I say that with respect, but I know I'm her biggest challenger."
