FIFA says it received "a claim from FC Nantes against Cardiff City in connection with the transfer." Sala, an Argentine forward, was killed last month before ever playing a match in the Premier League. The single-engine aircraft with Sala and pilot David Ibbotson on board crashed in the English Channel while flying from Nantes to Cardiff.
Nantes and Cardiff are in a dispute over the 15 million pound (about $20 million) transfer fee the Premier League club agreed to pay for its record signing. Cardiff officials have said they are "gathering information" on the circumstances of the accident.
