NANTES, France (AFP) - French club Nantes have referred their dispute with Cardiff City over the transfer fee of Emiliano Sala to Fifa, football's governing body confirmed on Wednesday (Feb 27).
The clubs are wrangling over payment of the fee following the tragic death of Argentinian Sala in an airplane accident in January.
Nantes referred the matter to the sport's global body after the Welsh side declined to pay an initial €6 million (S$9.2 million) of the €17 million total fee.
"We can confirm that we have received yesterday evening (Tuesday) a claim from FC Nantes against Cardiff City in connection with the transfer of Emiliano Sala," a Fifa spokesman said.
"We are looking into the matter and consequently we have no further comments at this stage."
Cardiff were due to pay the initial €6 million once the transfer had been registered but the club said they wanted to wait for the results of the investigation into the accident before transferring any funds.
"Cardiff City remains committed to ensuring fairness and accountability with respect to the agreement between Cardiff City and FC Nantes, but first and foremost the relevant authorities must be allowed to determine the facts surrounding this tragedy. It is inappropriate to comment further at this stage," Cardiff said in a statement.
According to the French club, the 28-year-old's move from France had been completed and an International Transfer Certificate (ITC) issued.
As the ITC had been registered and Sala had been confirmed as a Cardiff player, according to Nantes the Welsh club were obligated to pay for the transfer.
However, Cardiff are concerned about possible irregularities involving the flight from Nantes to Cardiff which resulted in Sala's death.
Pilot David Ibbotson, 59, was flying Sala to the Premier League outfit on Jan 21 when the accident happened.
Britain's Air Accidents Investigation Branch (AAIB) said on Monday the plane carrying Sala did not have a commercial licence.
But it said the journey would have been allowed as a "private" flight in which costs are shared between pilot and passenger.
It added that the basis on which Sala was a passenger had not been established.
Football agent Mark McKay had a mandate from Nantes to negotiate the transfer of the professional contract between the two clubs.
Nantes has said that the mandate had expired by the time Sala boarded the flight as he had already signed for Cardiff City.
The investigators also said that since the pilot's logbook and licence were not recovered, it was unclear whether Ibbotson was authorised to fly at night.
Ibbotson's body has not been found.
