Tunisia, aiming to qualify for their first World Cup finals since 2006, have sacked their coach Henryk Kasperczak, the country's football federation announced on Saturday.
The 70-year-old Pole, who guided Tunisia to the final of the 1996 Africa Cup of Nations, returned for a second spell in charge in 2015.
Tunisia were beaten quarterfinalists at the 2017 edition in Gabon, and friendly defeats since to Cameroon and Morocco spelt the end of the road for the well travelled manager.
"The decision was made yesterday (Friday)," federation spokesman Kais Reuez told AFP.
A successor will be named "by the end of the month," he added.
Tunisia face home and away 2018 World Cup qualifiers against the Democratic Republic of Congo in August-September.
