Anthony Joshua's professional record could hardly be better -- but he believes he will only improve now Rob McCracken is his full-time head coach.
The IBF world heavyweight champion will have McCracken in his corner for the first time in the paid ranks on Saturday when he makes a second title defence against Eric Molina at the Manchester Arena.
Joshua has stopped all 17 opponents as a professional since winning a gold medal at the London 2012 Olympics, when McCracken was his head coach as part of Team GB.
McCracken will still combine his work training 'A.J.' with Team GB's amateur boxing team in Sheffield and Tony Sims, who has coached Joshua so far in the pro ranks, will still be the lead second in the corner.
The 48-year-old coach trained British super-middleweight Carl Froch to three reigns as world champion and Joshua hopes his experience will benefit him with bigger tests looming in 2017.
"Rob brings amounts of experience," Joshua told ESPN.
"You can tell by the people he brings in for sparring. He has been a mentor for so many years.
"He's just a good geezer and it helps a lot having people in your corner that you can trust.
"He brings world championship-level experience and he's got a bag of fighters who want to work with him and connections.
"He's just well respected and I like to work with people who have been in the game and know what I'm going through rather than someone you can just hold. He has just been in the game so that speaks volumes to me.
"That's why I don't go to press conferences running my mouth off, I try to conduct myself in the right way. It's because I have a good mentor alongside me, he's a good asset."
Joshua, who is from Finchley in north London, is being lined up to face Wladimir Klitschko in April, either at Wembley Stadium in London or the Principality Stadium in Cardiff.
The winner of David Haye-Tony Bellew on March 4 is a possibility for a summer showdown for Joshua, or even rival world champion Deontay Wilder, the American who holds the WBC title.
But Joshua is not allowing himself to be distracted from the task in hand, 34-year-old American Molina (25-3, 19 KOs), who was knocked out in the ninth round by Wilder in June last year.
"When I hear David Haye talking it's like, 'You're not really relevant right now'," said Joshua.
"Everyone has their journey set out and I have mine set out, so I'm not really worried about him because if I beat Molina, I've got Klitschko.
"All fighters that come in are probably 10 percent better than what we have seen from them before because there's a chance they could become the champ.
"If I want to fight Haye, I'll fight Haye. Whether he beats Tony Bellew or not it doesn't matter because boxing is not just about who you beat, it's about if it makes sense and if it makes sense I'll fight him. After his fight he'll look at his situation and if he wants to come for me, no problem.
"Tyson Fury isn't contributing to the heavyweight division now so he can't really comment. I don't see anything wrong with the division, boxing is thriving, everything is on track."
