Neumann is one of two Wales wings who are the pride of St Davids, Pembrokeshire, with Jasmine Joyce currently enjoying success on the World Sevens Series with Great Britain.
She is the oldest of triplets, and credits her “sporty” family for the support they have shown throughout her career.
And Neumann beamed of pride when asked about the success of her sister at the recent Welsh Rugby Union National Cup Finals, which took place at the Principality Stadium on the same day Wales beat Scotland in Edinburgh.
Jana Neumann was named player of the match as Haverfordwest Ladies (Lisa’s former club) beat Merched Clwb Rygbi Cymry Caerdydd 20-17 to win the Bowl.
“It was incredible, she is doing so well,” Neumann added.
“She did an interview because she got player of the match, and she still speaks about me and my rugby journey.
“It’s amazing that my family was there in the stadium to support her.
“Whatever we put our mind to we just go out and achieve, I guess.”
The Neumanns will no doubt be among the 8,000 ticket holders on Saturday, where Wales will be looking to upset the odds and beat England for the first time since 2015.
