Taylor has done little wrong in her professional career, winning the world title in her seventh bout to extend an unbeaten record, but McCaskill insists she has spotted vulnerabilities in the Olympic gold medallist.

"I think the best advantage I've had in a lot of my fights, is that I'm the underdog," McCaskill told Sky Sports.

"Usually my opponents have had titles, or they've had more fights, or they have been the rounds before that I haven't been.

Katie Taylor, I see a lot of mistakes, and I just want to be able to take advantage of those situations.

"This is my first 10-round fight, and I think we over prepare, and we anticipate the worst situation. We prepare very well for these things.

"Katie Taylor, I see a lot of mistakes, and I just want to be able to take advantage of those situations."

Promoter Eddie Hearn has issued words of caution to Taylor, pointing out that she cannot afford to neglect her defences against the American.

"It's a dangerous fight," said Hearn. "McCaskill is a big puncher.

"Katie Taylor took too many shots in that fight at the Millennium Stadium when she won her world title. She wasn't 100 per cent in camp, she is now, no excuses, and I think you're going to see a great performance.

"You're going to see a great fight and a great end to a wonderful 2017."
