Yanga will be out to reclaim the bragging rights, having beaten Simba 1-0 in a Premier League tie at Benjamin Mkapa Stadium in Dar es Salaam.
Hassan Bumbuli, Yanga's information officer, said with Simba having lost the Premier League's clash to his outfit, the Sunday encounter will be a payback.
He said Yanga understood the vengeful mood in their rivals’ camp.
Bumbuli revealed: “They will be out for revenge, but we won’t give them room. It is not only about trophy but also pride and superiority.''
“The last time we played them we won, they will be playing under pressure to please their fans. I am confident we will win taking into account the preparations we had,” he said.
He also said winning is the other motivating factor in the camp, seeking to give the team's supporters something to smile at.
"We are ready for them, the players and everyone at our club are ready, we will beat them at Lake Tanganyika Stadium, this year we did not win the Premier League so winning the ASFC top honour is a must to us, we want to give our supporters something to smile on," he said.
Bumbuli said the morale in his camp is high as all players are in good shape and they are enjoying full support from the team's management and supporters.
"Everything is going on very well, the management is fully supporting the team, we are having good support from our supporters, the situation is just very good," he said.
Simba SC information officer, Haji Manara, said it will be payback time on Sunday.
Manara pointed out: "After our last Premier League's tie against Namungo FC, the players were given some time to rest, but now they have started the preparations, we are going to win at all costs.''
“It is true Yanga have had an edge over us in the past game because we made some mistakes in that game, but the coach and his backroom staff have worked on the shortfalls and the boys are raring to go,'' he said.
