Fabian Hurzeler has called on Albion to complete their European mission when they return to English soil.
The head coach acknowledged his side struggled to find their flow during the goalless encounter in Norway.
Brighton controlled the ball for large periods and tested the opposition defence with numerous efforts and crosses into the penalty area.
Despite their dominance, they could not break the deadlock in the opening leg of the Conference League play-off tie.
The visitors were almost made to pay on the counter-attack, with Bart Verbruggen producing an excellent stop to deny leading scorer Heine Asen Larsen, while Isak Vadebu also passed up a clear scoring opportunity when clean through on goal.
When questioned about what he could take from the stalemate in Scandinavia, Hurzeler told The Argus that his team had kept an clean sheet and crafted openings.
He acknowledged that Tromso created two significant chances on the break.
Ultimately, he believed his players were not operating at their usual tempo.
He explained that it marked the season opener and the team was still finding its rhythm.
The squad generated opportunities, though not the highest quality ones.
He also praised Tromso’s defensive organisation, noting they were a strong side who had anticipated the challenge.
The positive takeaway, he suggested, was that their destiny remained in their own hands.
While not the outcome they had desired, the return leg would be played in front of their own supporters, presenting a significant chance to progress.
His immediate focus would be on the Villa match before preparing for the crucial second leg and qualification for the Conference League.
Brighton made the journey straight back and were expected at their Lancing training ground on Friday, ahead of their Premier League curtain-raiser against Aston Villa on Sunday.
