It’s been three years since Taylor became undisputed light-welterweight champion with victory over Jose Ramirez in Las Vegas.
That was arguably the last time the Tartan Tornado performed anywhere near his best, but the Scot is adamant he is still in his prime.
“I know what I can do,” he said. “I’ve had a stellar career and I’ve got a great bunch of people around me as well.
“They would be the first to say to me, ‘Look, you’ve done it, you’re not performing the same’. But the way I’m performing in the gym, the sparring sessions I’ve been putting in, the running, my body’s coping well with everything.
“So yeah, I’m still in the prime of my life. I’ll continue to box and after I take care of business on Saturday, it’s only big fights again, back on the chase and getting titles back.”
Meanwhile, Catterall predicts he will knock Taylor out between rounds six and nine and says “it will be a relief” to finally put their bitter rivalry to bed.
The Chorley fighter told BBC Scotland: “It’s a fight that’s been talked about way before the first fight and then two years in the aftermath, so our names have been linked.
“In a round about way, it’s good for boxing and it’s good for us, the rivalry we’ve created. But to win convincingly, draw a line under it and move on with my career, that’ll be good.”
