Ryan said: “You’ve got a lot of people saying it’s 50/50. I respect Terri, really nice girl, but I’m very confident.

“I don’t see it being 50/50, so this is where I can make a statement.

“[This is a] fight that will give me more recognition, build my name and reputation.”

Ryan has overhauled her coaching team, and her life, since the draw against McCaskill. She has sparred with two-weight undisputed champions Katie Taylor and Claressa Shields and relocated her training camp to Las Vegas.

Ireland’s Taylor specially thanked Ryan for helping her overcome Chantelle Cameron in their rematch last November.

“That says a lot in itself,” Ryan says. “Katie doesn’t talk a lot so for her to say that, I’m grateful.”

Cameron might have been undisputed light-welterweight champion before she fought Taylor, but beating the pound-for-pound star in Dublin propelled the Northampton fighter to the main stage of boxing.

Ryan wants the rematch with McCaskill, who is now scheduled to fight Lauren Price on 11 May in Cardiff.

Keen to have her own big moment, Ryan hasn’t seen much of the famous Strip in her eight weeks in the States, instead “locking” herself away in training, inviting Shields to Vegas to spar.

“I don’t really know other females who have sparred them both,” Ryan says of Taylor and Shields.
