The Amakhosi came from behind to defeat Usuthu 2-1 in their Absa Premiership encounter at the Moses Mabhida stadium, courtesy of a George Lebese brace after the interval.
AmaZulu found the net through Bafana Bafana target man Bongani Ndulula.
Despite Usuthu giving the Phefeni Glamour Boys a good run for their money, the 32-year-old playmaker said they kept believing they would walk away with maximum points after 90 minutes - and their optimism worked in the closing stages.
“It was a tough one,” said Letsholonyane.
“They didn’t give us enough room to play our normal football.
“Obviously they were parking the bus.
“Our coach (Baxter) said at half-time that we are playing too much in the middle where they are.
“He told us to make use of our wing play and try by all means to put early crosses for our strikers and we managed to score.
“We tried by all means to keep our penetrations, believing in ourselves that we will win the game.
“And fortunately Shabba (Simphiwe Tshabalala) ‘s free-kick went back to George (Lebese) to finish from a rebound.
“And we managed to get the three points.”
Chiefs’ triumph extended their lead to 11 points over second-placed Chippa United in the standings.
Chiefs' next league game will be against Mamelodi Sundowns on Saturday, November 22.
