Uganda coach Bobby Williamson says he wants to deliver a first Africa Cup of Nations qualification in 33 years 'for the Ugandan people'.
The Cranes need just a point from their penultimate Group J qualifier in Angola to reach their first finals since 1978.
"I don't want to let them down - nor the president and technical committee of the Ugandan FA," the Scot told BBC Sport.
"They have worked very hard to get to this situation and to this point.
"I want to be successful for the Ugandan people."
"It won't be an easy task in Angola and I'm sure that come the day I will be a bit nervous."
Williamson, who has been in charge since 2008, welcomes back Cranes captain Ibrahim Sekadjya, who plays his club football in Austria, for Sunday's match in Luanda.
In the past, the Scot has spoken of the need to dampen down expectations back home in football-mad Uganda.
Losing finalists to champions Ghana in 1978, the Cranes have never been back to the finals since.
And Williamson believes an ability to focus on the match will be key to his side's chances of success.
"If our players are focussed, disciplined and remember what's asked of them and do the best they can, we will get the result we are looking for," said the 50-year-old.
"It's always difficult playing away from home in Africa, but we're confident without being over-confident.
"Hopefully, we will get the luck and breaks to get the point we need."
Should Williamson's charges fail to earn the point they need, they will have one final chance at home to Kenya in their final Nations Cup qualifier in October.
The Cranes lead Group J with ten points, four more than Angola while Kenya have four and Guinea-Bissau three.
In the group's other game this weekend, Kenya host Guinea-Bissau on Saturday.
