The Belgian tactician hailed his charges for showing commitment throughout the encounter despite their 4-1 win over the Eswatini outfit in the first leg match held in Tanzania last week.
He pointed out his team's concentration is now on the coming games in the continental tournament.
He said the win has boosted morale in the camp but warned his charges against complacency in the coming games, noting the journey has just started.
The coach said he is happy and proud of his players for displaying a great performance and avoid being carried away despite recording a big win in the first leg.
“We came here for nothing short of a win and we controlled the game well, we never lost focus at any stage of the match," he noted.
"We knew Swallows would open spaces since they wanted to reduce the score line hence we managed to crack their defense."
"We will continue working hard in the next round since our mandate is to reach the group stage of the competition.”
Simba scored through Clatous Chama, who netted a brace on the 27th and 32nd minutes, Emmanuel Okwi and Meddie Kagere, who scored on the 50th and 68th minutes respectively.
The Msimbazi Street side is waiting winners of the preliminary round's duel pitting Nkana of Zambia against Uniao Desportiva do Songo of Mozambique, slated for yesterday in Zambia.
Winners of the game between Nkana and Uniao Desportiva do Songo will play Simba in a two-legged first round match later this month.
Meanwhile, Mbabane Swallows' assistant coach, Musa Manyatsi, is reported to have attributed his squad’s defeat to lapse in concentration.
“We were punished by the opposition after conceding soft goals due to lack of concentration," Manyatsi, speaking on behalf of the squad's acting head coach Kinna Phiri, disclosed.
"We wanted an early goal that could have boosted our morale but the opposition capitalized on our mistakes and punished us.”
He further said: “We will take the positives from this match to prepare for the future.”
The capital city giants were handed an 8-1 aggregate drubbing by Simba, who shattered the former’s dreams of advancing to the first round of the continent’s premier club competition.
