Sam Warburton's agent has said that despite the flanker's eagerness to stay at Cardiff, the Blues cannot offer him a deal due to the European saga.
The Wales captain, whose contract runs out at the end of the season, helped lead the British and Irish Lions to glory in Australia earlier this year.
But his agent, former international Derwyn Jones, has revealed that the Blues have not been able to make a new offer due to an uncertain budget.
"Sam Warburton has told Cardiff Blues that he wants to stay in Wales next season," Jones told Y Clwb Rygbi.
"But the region aren't able to offer him a contract at the moment because of the mess that exists in Europe.
"They don't know how much money they will have next year."
He added: "Five weeks ago we said to the WRU and Cardiff Blues that Warburton wants to stay in Wales, but there is no contract offer on the table because of what is happening in Europe."
"There is only so much time that guys like Warburton, Leigh Halfpenny and Adam Jones can wait until there is a contract offer, so the WRU and the regions must get together and do whatever they can for the good of Welsh rugby.
"[There must not be] the kind of power struggle that has gone on in the past [between the WRU and the regions] and they must do it now.
"If they don't do it now then these players will be going."
