Walsh is part of a boxing brotherhood.
His twin brother Liam was a former British and Commonwealth super-featherweight title holder and challenged for a world crown in 2017, while older sibling Michael had an unbeaten record of 14 wins with 13 knockouts to his name.
Following his win against Mould, Walsh celebrated with his arms outstretched and told BBC Radio Norfolk that it was a tribute to his brother Liam.
“My brother Liam did that celebration before and I think it’s a moment thing,” he said.
“After I’d taken the moment to really soak it in and enjoy it, I was saying to Liam ‘a lion doesn’t celebrate when it catches its prey’ and that’s what I felt like the second he (Mould) was walking to that ring.”
The two boxers traded personal insults at the weigh-in before the fight, so there was an added friction to proceedings.
Walsh continued: “I was just excited. I told him (Mould) the day before: ‘I can’t wait to get my hands on you’. I was genuinely really happy to put my hands on him after the things he’d said.”
Walsh, known as ‘Iron’ Ryan, said he is ready to step up to a bigger stage and possibly compete in the current home of big-money prizefights, Saudi Arabia.
“If the money stops tomorrow and we don’t need it any more, I’m still in the gym, I’m still hoping someone wants to fight me,” he added.
“It’s never been because of the financial gains why I love this and that’s why I’ve had the longevity that I’ve had.
“Although, it is nice if you can have a few bonuses as I’m only going to spend it on a few holidays with the kids and my girlfriend,” Walsh said.
“[The win over Mould] was definitely up there with one of the best moments and best memories, this ‘Riyadh season’ can stretch that financially and for the moments.”
