The service will be held on Saturday, with Nantes defender Nicolas Pallois also reported to be attending. Warnock and Choo will form part of a Cardiff delegation at the funeral, which will be held in the town of Progreso in the Argentinian province of Santa Fe. Sala's body will be brought back to Argentina on Friday.
Cardiff have promised to continue working with authorities to establish how the plane crash happened. Cardiff chairman Vincent Tan released a statement last week which said: "Cardiff City will continue to work with the AAIB and investigators to find out how the crash happened and to assist Emiliano's family.
"We have offered to them to arrange to take Emiliano back to rest with his family in Argentina. Even though he will be there his soul will always be in our hearts. We feel a tremendous loss but the biggest loss is borne by Sala's family."
