“It is unsettling for the players . . . especially our top players who are maybe being attracted to other clubs in England and France because there's more certainty of where they'll be playing next year. ”

The deal would tie the regions into playing in the Pro12 and Heineken Cup and making players available for international matches, while setting out the funding coming from the WRU for the next five years.
RRW, which represents the regions, has urged the WRU to ensure the four teams' future funding can match the finances available to their English, French, Scottish and Irish counterparts.
The regions stated: "A solution must be reached by the end of January 2014.
"Should this not be possible, the regions will have no choice but to pursue further competition options immediately."
RRW added: "It continues to be the absolute intent and strong desire of RRW and the regions to work with the WRU in progressing such a positive position for the next five years of professional rugby in Wales, or indeed to discuss any proposals WRU themselves may have that could provide an even stronger platform for sustainable and competitive professional rugby across Wales.
"Without change, professional rugby in Wales will fall further and further behind the rest of the European game."
The WRU has a legally binding obligation to enter four Welsh teams into the Pro12 and Heineken Cup next season and without the regions, it would have to develop new sides capable of competing in those tournaments.
Reacting to the regions' statement, the WRU said Welsh "teams" would play in the Heineken Cup and the Pro12 next season, and any cross-border competition would need to be approved by the relevant unions.
The WRU will now draw up a new participation agreement "focused on recognising and rewarding regions which identify, develop and retain players capable of challenging for international honours with Wales".
