Lyon, the eight-time European champions and current holders of the Women's Champions League title, had never conceded more than four goals at home before this week.
On Wednesday, Arsenal came along and not only smashed that record, but also inflicted a biggest-ever defeat in this competition on the side that has dominated it for so long by winning 5-1 in France.
It was the headline result from the first round of group stage fixtures in this 2022-23 season, which wasn't without incident elsewhere, either.
Whether it was Barcelona hitting Benfica for nine, Chelsea leaving Paris with three huge points or Roma getting their first ever win in the Champions League proper, there was plenty going on across matchday one.
