Ethiopia coach Sewnet Bishaw believes they must face their last encounter against Nigeria with a hunger for goals if they are to go through to the quarter-finals.
The Walya Antelopes were defeated 4-0 by 10-man Burkina Faso in their second match in Group C.
"We didn't expect this result from the very beginning. We hoped that we would play again like the first game and take a point against Burkina Faso," said Bishaw.
The Antelopes still have a mathematical chance of qualifying for the last eight when they play against the Super Eagles and Bishaw is determined for his side not to go out on a whimper.
He added: "We're not going to the field to defend, because defending will only give you one point. Now we must try to play against Nigeria to score goals to have three points.
"If we get three points, in total we'll have four, and may qualify for the next stage.
"Not only will we just score one or two goals, we need to score lots of goals, otherwise, it is a matter of dignity for our boys."
