Cardiff City could launch a negligence claim against Nantes as soon as next week if an official report finds Emiliano Sala was flown to his death by a pilot who did not have the correct licence, according to Britain's Sunday Telegraph.
Premier League side Cardiff already find themselves involved in a legal dispute with French side Nantes over whether they are contractually obliged to pay a transfer fee for the Argentine striker, who died without playing a game for the Welsh side.
Sala had signed for Cardiff for a club record £15 million (US$19 million) and was flying to his new team from former side Nantes in France when his plane went missing over the Channel on January 21.
The wreckage was located on the seabed. Sala's body was recovered but pilot David Ibbotson is still missing. The aircraft remains under the sea.
Details of how Sala died, and who was responsible, could be clarified in the coming days by Britain's Air Accidents Investigations Bureau, which had previously said it intended to publish an interim report into the crash within a month of it occurring.
Sala was buried in his hometown of Progreso in Argentina on Saturday, with Cardiff manager Neil Warnock and club executive Ken Choo among the mourners.
"It was important for us to come and pay the respect to the family," Warnock told AFP. "People tell me: 'He never played for you,' but he was my player, I signed him, we had two or three conversations and he told me he would score the goals to keep Cardiff in the Premier League."
