The Tanzania football big guns' Head of Information and Communication Department, Haji Manara, said the team is in perfect frame of mind ahead of the clash against the Mozambique side.
Manara did not issue more details of the team's trip to Mozambique only saying they are well prepared for the game.
"The team is to jet off to Mozambique tomorrow to play against Uniao Desportiva do Songo on Sunday, the team is in perfect frame and we are confident of doing well," he said.
However, unconfirmed reports say the team depart without three players, keeper Aishi Manula, midfielder Ibrahim Ajibu and defender Wilker Henrique da Silva.
The two teams will play on Sunday before the return leg, slated for two weeks later at the National Stadium in Dar es Salaam.
Aggregate winners of Simba SC against Uniao Desportiva do Songo clash will face aggregate winners of the game pitting FC Platinum of Zimbabwe against Nyasa Bullets of Malawi to seek qualification for group stage of the continental competition.
Simba's head coach Patrick Aussems is reported to have said he is optimistic of good results in Mozambique.
The coach issued the comments on Tuesday after his side had cruised to 3-1 win over Power Dynamos of Zambia in an international friendly at the National Stadium.
Aussems said the team will strive to get good results away from home on Sunday.
“We don’t know the team [UD Songo] well, I have not seen them play, but we will do our best and get a convincing result to take back home,” he said.
On paper, UD Songo seem pushovers, but they are not a side people should underrate as the club posted victory over DRC big guns TP Mazembe two years ago.
