The AAIB says the pilot of the Argentine's plane was exposed to the poisonous gas before a fatal crash in January
Cardiff City are "concerned" by the results of the latest report from the Air Accidents Investigation Branch (AAIB) into the death of footballer Emiliano Sala.
The striker, along with pilot David Ibbotson, went missing when their plane crashed over the English Channel in January, days after his move to the Premier League club from Nantes was announced.
Sala's body was later recovered from the wreckage, but Ibbotson has not been found.
