The 37-year-old trainer insisted he needs to treat each of his fighters differently as some respond better to “the stick” and others “the stroke”.

He told Boxing News magazine: “In psychology, there’s either the stick or the stroke. Certain people need a stroke of encouragement, whereas others need a stick to crack them into position, meaning they respond better to authority.

“It’s just about figuring out that particular individual and working on a way to get through to them – giving them confidence without gassing them up too much.

“This is a dangerous sport, so you can’t just focus on making fighters feel good all the time.

“They have to go through all different emotions in camp and overcome a lot of obstacles to be able to succeed in this horrible game.

“But there’ll also be days when everything just fits, so it’s about taking that same energy into fight week and making sure that, mentally, they’re in a strong place.

“This game is all mental at the top end, so the way you talk to a fighter is the most important thing [as a coach].”

Shane also believes a trusting relationship between a boxer and their coach is vital.

He said: “Nobody is a perfect coach but you’ve got to build a relationship – that element of trust – with your fighter.”
