All four Welsh regions have offered their full support to joining the breakaway Rugby Champions Cup with English and French clubs.
The Blues, Ospreys, Scarlets and Dragons have released a joint statement through their umbrella organisation, Regional Rugby Wales, confirming their desire to join the new European competition.
Meetings regarding the future of the European Cup are set to take place in Dublin on Wednesday and Thursday to save the competition, but the Welsh regions have now nailed their colours to the mast.
The news gives the Anglo-French alliance crucial support in their bid to build a new tournament, featuring 20 teams and run by the clubs as opposed to the unions.
Teams from Wales, Scotland, Italy and Ireland have all been invited to join.
"Regional Rugby Wales, on behalf of the four Welsh regions, confirms its full support for the proposed new Rugby Champions Cup competitions," read a statement.
"Whilst there remain elements of detail to be confirmed, it is now clear that there are a number of significant advantages to the new competitions in equality of governance, format, qualification and distribution across the individual participating clubs.
"Consequently, RRW looks forward to working with the WRU (Welsh Rugby Union) to support their efforts and positive engagement in striving to ensure our teams are involved in strong, valuable European clubs competitions in time for next season."
