The two teams played a goalless draw in the first leg duel at the National Stadium in Dar es Salaam on Saturday and the Belgian tactician promised to come out stronger in the return leg match.
Aussems said the return leg match will be difficult but he is confident that his charges will win and progress to the semi-finals of the premier continental club competition.
He said the Saturday results were not bad to his side, insisting he has taken positives from the game.
The Belgian tactician said he is confident his squad will emerge as winners in Lubumbashi as playing away gives players more freedom.
He said on Saturday, his team was outstanding in all departments as they played strong game, they were matured and much disciplined.
"The Saturday results were not that good to us as we have failed to collect maximum points, but I would say the goalless results are better than 1-1 draw, I am sure we will emerge winners in DRC, we will polish some few problems which saw,” he said.
The Saturday results were the first for Simba in the tournament this season as the Msimbazi Street based side has won all of their games at the National Stadium.
However, considering Simba away games record, especially in the group stage of the tournament’s games in which the team conceded 12 goals without scoring, many are doubting if the squad can post a win in Lubumbashi.
Aussems though said his squad has been improving in all of its games and Lubumbashi will not be exceptional.
"The performance of my team is improving each passing game, I am sure in Lubumbashi the team will do well,” he said.
The coach employed a brave system, which saw his side control possession of the ball for the whole 90 minutes.
During the game, Simba played with passion and purpose as they were more creative going forward, with Meddie Kagere and John Bocco being a thorn in the visitors’ flesh.
Simba are to blame themselves for failing to use numerous scoring opportunities they created, as well as a penalty which skipper Bocco missed on the 58th minute of the game.
One of the visitors’ coaches, David Mwakasu, disclosed in a post-match interview Simba are a good side, but they will face tougher opposition in Lubumbashi.
