Newport Gwent Dragons say Taulupe Faletau’s decision to join Bath at the end of the season is “the worst possible” outcome to his transfer saga.
Faletau, 25, has rejected an offer of a national dual contract (NDC) with the Dragons and the Welsh Rugby Union.
Dragons chief executive Stuart Davies said he is “extremely disappointed” by the decision and questioned the WRU’s handling of the negotiating process.
The WRU say it liaised with the Dragons “on all developments” during the talks.
But Davies said: “I want to fully review how the negotiation was handled. I need to understand it for my own piece of mind.
“And in a wider context I’m tired of Toby and the Dragons being a test case for these policies, procedures and documents.”
Faletau had been set to join Bath in October but a move was blocked by Wales head coach Warren Gatland.
The proposed transfer would have involved a fee because the number eight was under contract, but he will now join the English Premiership side for free when his deal ends at the end of the season.
“It’s the worst possible scenario for the Dragons as an outcome,” said Davies.
“The value of the transfer was significant. Some of the figures I’ve seen bandied around didn’t do justice to what it meant to us in terms of a figure.
“And obviously the NDC not going through now is the knockout follow-up.”
