Since forming two years ago, the Ospreys have quickly established themselves as Wales' pre-eminent region, blending the traditional Neath-Swansea rivalries into a brand new side which has attracted a remarkable number of core supporters from both teams.
As Roger Blyth, Joint Managing Director of the Ospreys explains, "Over the last two years, we've worked extremely hard to establish a truly regional rugby side. We have a superb set of core supporters from Neath and Swansea and now we really want to reach out to the rest of the region. It is vital for the future of Welsh rugby that all the other professional sides take regional rugby as seriously as we do."
Mike Cuddy, Joint Managing Director, adds, "We've merged two great clubs with differing ideals and visions into one of the most exciting teams Europe. In renaming ourselves as the Ospreys we're showing the whole area, and the whole of Wales, just how committed we are to regional rugby. Furthermore, expanding our fanbase is a vital step if we are to maintain our position as the best team in Wales and it also provides a huge springboard in our quest to win the Heineken Cup."
