Sono was compelled to manage his own club in 1994, when they were relegated to
the second division.
Under his tutelage, Cosmos made a swift return to the premier league. But he has never won a trophy as a coach.
In last November's League Cup final in
Johannesburg, his club handed an embarrassing 5-0 defeat to Kaizer Chiefs.
Sono is currently the longest serving coach in the premier league and sits on the Premier Soccer League board.
He had a reputation for uncovering young stars and turning them into international players.
But his club lacked the financial wherewithal to hold onto them and build a side that could rival Kaizer Chiefs or Orlando Pirates.
Instead, Sono has sold more than 20 South African footballers to European clubs over the last five years.
His most recent sale involves his own son, Bamuza, who flew for trials at St Gallen in Switzerland last week.
Sono has been a vocal critic of the South African officials, who have tried to keep him quiet by appointing him to positions within the South African FA.
In 1998, Sono was appointed as caretaker coach of Bafana Bafana, following the
resignation of Clive Barker.
His first match in charge saw the country embarrassed in a 3-2 defeat by lowly
Namibia in the Cosafa Castle Cup.
But Sono and his players restored national pride, by reaching the finals of the Nations Cup in Burkina Faso.
