Following an unconvincing run of fixtures for Chelsea, with back-to-back draws before Sunday's narrow victory over Tottenham, this was exactly the display Bompastor would have wished for.
While opposition low blocks have often stymied the final-third spaces in which Chelsea would usually flourish, they remained resolute in their attacking efforts and seized chances once the momentum shifted.
Thompson stole the show before being brought off in the 56th minute as her blistering pace proved too much for the visitors to handle.
Impressive, too, was the quality of her display when she evidently is yet to have fully adjusted to her new surroundings.
At times, a lack of connection was apparent as runs were misjudged or team-mates failed to switch on to her movement, but even an imperfect Thompson was enough to significantly trouble Paris.
The change with which Thompson departed highlighted another element crucial to Chelsea being able to deal with dogged defences - she was one of three who went off as Kerr, Reiten and Maika Hamano came on, all substantial attacking threats.
Bompastor later brought on England full-back Lucy Bronze, who had a cameo at the weekend in her first game since the Euro 2025 final and revealing she had played the entire tournament with a broken leg.
Bronze is just one important player who is returning to fitness. Lauren James is still sidelined following an ankle injury at the Euros and her strengths could have helped Chelsea to do even better against the compact backline as - before Paris' collapse - the Blues missed her ability to pick passes and weave through defences.
Another commanding victory shows how Bompastor has shaped a relentless side who can grind out games in Europe.
