It felt a matter of when - not if - Chelsea would qualify for the quarter-finals after such a strong start to their campaign, and they did so efficiently.
Knowing they needed just a point before kick-off, Chelsea could have been forgiven for playing it safe, but they went on the attack immediately and Bronze's goal put them on the front foot.
Celtic, who proved hard to break down last week having caused a stir when they went 1-0 up, had barely settled when Chelsea doubled their lead and seemingly put the game to bed.
Not even half an hour had been played and Celtic's task was a tall one, needing nothing less than victory to keep their slim European hopes alive.
They worked tirelessly to try to win the ball back but did not have the space or numbers up front when they did, or the composure to keep possession.
Manager Sadiku acknowledged this week that Celtic are "learning" in the competition, but this was always going to be one of the toughest lessons - and they struggled to find answers.
Chelsea captain Millie Bright, returning to the side after being rested last week, dictated most of the play from the back, switching possession as the hosts looked for a way through.
In the end, it was from two set-pieces and the penalty spot that Chelsea scored the goals they needed to progress in a fairly routine group-stage campaign.
Bompastor was cautious in the build-up to the match this week, reminding her players to "keep their heads on their shoulders" and continue to improve, despite an unbeaten start to the season.
But the ease with which Chelsea have qualified for Europe's last eight will have not gone unnoticed by their rivals - they are a team building impressive momentum.
