Jenny Murphy believes Irish women's rugby has not developed enough in the time period since the senior team's historic Grand Slam win in 2013 and feels more support is needed.

Speaking on RTÉ 2fm's Game On as she reminisced about that first ever Six Nations triumph seven years ago, the Grand Slam winner described that relative lack of progress as "really disappointing".

"Playing numbers have gone up and there has been some amazing talent that has come through the squad but can the team do better? I think they can because they've got the talent there," she said.

"I just don't think that they are supported enough.

"They've had their Six Nations games last year [and then] no summer tests; one game in November. You need more matches the better.

"We need and Under-20s squad - we don't have that. I think we're the only women's Six Nations squad to not have an Under-20s side.

"Hopefully that's changing soon but you would just like to see more support because teams in the past have done well and you constantly want to build and drive on instead of going with the motions and 'ah sure, it's good enough'.

"I just think you're letting down a side that, at the moment, has a serious amount of potential."

Murphy contrasted the structures in Ireland to the professional pathways in England and feels that the pathways on this island are "not as clear".

"I know that there is a better way of doing things than what's currently happening at the moment," she added.
