Faouzi Benzarti was sacked as Tunisia coach on Saturday, just four days after leading the 'Carthage Eagles' to the 2019 Africa Cup of Nations finals.
Benzarti, 68, only took over at the end of July, succeeding Nabil Maaloul who had quit following Tunisia's World Cup campaign in Russia where they beat Panama but lost to England and Belgium.
Benzarti's two assistants, Maher Kanzari and Mourad Okbi will take interim charge of the national team "until a new coach is named in 2019," said Tunisian football federation spokesman Kais Reguez.
Tunisia made sure of their place at the 2019 Africa Cup of Nations to be played in Cameroon by beating Niger 2-1 on Tuesday, their fourth win in four group games.
Egypt, who are second in Group J of the 2019 AFCON qualifiers with nine points, are set to face the group's leaders Tunisia in the 5th round on 16 November.
