Cardiff City say they are to sue Nantes for damages over the Emiliano Sala tragedy with immediate effect in a move set to run into multi-millions.
It comes after Swiss authorities ruled they were unable to overturn a decision by the Court of Arbitration for Sport which had previously rejected Cardiff's appeal against FIFA's demand for the first instalment of the £15million Sala transfer fee to be paid.
Cardiff say the judgement by the Swiss Federal Tribunal is not an unexpected one, but they feel a need to go through the thorough legal process step by step. CAS are based in Lausanne and subject to Swiss law.
