Kevin Barry is confident that he is better equipped to handle the pressures of a major world title fight - after being days away from another chance to get himself a unified heavyweight champion.
The 58-year-old veteran trainer, was the boxing brains behind David Tua when he lost a twelve round unanimous decision to then IBF, IBO, WBC world champion Lennox Lewis in 2000.
He worked with Tua until 2003 - but then they parted ways on a sour note and a lawsuit erupted between the two.
Barry was able to guide Tua to the world title shot, after a very strong run together in the 1990s.
Tua would lose the bout convincingly, as he was unable to deal with Lewis vast advantage in height and reach.
17 years later, Barry gets another chance at glory on Saturday night, when he heads the corner of WBO champion Joseph Parker as he faces IBF, IBO, WBA champion Anthony Joshua before a crowd of 80,000 at Principality Stadium in Cardiff, Wales.
Speaking to Brendan Telfer on Saturday Sport, Barry said - "I'd like to think that over the last 17 years my style of coaching and my way of doing things has developed and evolved. I think I'm a much wiser guy than I was in November of 2000. I think I'm far calmer and more mature and I look at things a lot differently.
"You can see with what I've done with Joseph over the last five years, when we've made big strides for a young guy. That comes from experiences that I've had over that period of time.
"I know that Joe has a lot more skill than Anthony Joshua; I've always believed that. But if he's going to win this fight, he needs to draw down on all that skill and he needs to produce a career-defining fight by fighting his best performance."
