The Dockers were seeking for revenge against Ingwe having gone down by a similar margin in the first leg played in Mombasa.
But a strike from Abdalla Hassan was enough to earn revenge that has left the former Tusker coach smiling.
“There is nothing sweeter in football as avenging defeat and I am happy we have beaten them. They surprised us in Mombasa in a match we had expected to win, so this victory is enjoyable," Nkata told KPL website.
Ingwe coach Robert Matano was left frustrated after his side squandered a number of scoring chances. “This is a very bad feeling for me because we had a share of good chances but wasted them."
The win left Bandari on 5th position with 29 points while AFC Leopards are lying 13th after collecting 20 from 19 matches.
